1 General Description

The AIM-9440, Analog Input Module (AIM) provides the interface between the external system analog signals (such as currents from a transducer) and ePAQ- 9410/ePAQ-9420 Multifunction Gateway units (ePAQ).

The AIM can accept up to 32 input signals in the form of low-level voltage or current loops. Each input is equipped with a scaling resistor to convert current from transducers to dc voltages (i.e., 5.0 volts full scale).

Using specialized A/D circuitry and a micro-processor based sub-system, the AIM scans the analog signals and communicates the data back to the ePAQ via one of its’ two RS422 communications ports.

Each AIM contains two RS422 ports for communications. The two ports are provided for use with redundancy applications where it may be desirable to have two ePAQ units communicating with the AIM. Each communication port consists of two RJ45 connectors, for daisy chaining the communications line from one AIM to the next.

Each AIM is addressable via on-board dip switches. Up to 256 addresses are available.

The AIM includes various LEDs for diagnostics. Two LEDs for each communications port provide TX and RX indication. An LED is provided to indicate microprocessor health (heartbeat, or HBT) and power supply condition (PWR). A good AIM will show the heartbeat LED blinking at a 1 second duty cycle, and the power LED will be on. If a failure occurs, the power LED may be off, and/or the heartbeat LED may not blink.

Standard analog input scaling in the ranges of +/-5Vdc, +/-10Vdc, +/-0 to 1 mA, and +/-4 to 20 mA are available as an option (see ordering information).

Each AIM is equipped with pluggable terminal blocks for field wiring of the analog inputs.

AIM modules are designed for 19 inch x 4U typical rack mount applications.

2.3 Addressing / System Capacity

Each AIM Module is addressable via 8 dip switches labeled “Address” on the front panel (SW2 on the circuit board). Up to 256 individual AIM module addresses are available. 256 modules x 32 analog points per module = up to 8192 hardware analog points available. Note: The specific ePAQ protocol in use determines the actual number of analog points supported.

2.4 Configuration

Configuration for the AIM modules is accomplished through the hosting device (such as ePAQ, etc.) using CGA’s ConfigWiz 2.0 software. Configuration can be accomplished either locally or remotely.

Consult the CGA ConfigWiz 2.0 User Manual (UM-2018) for additional information.

2.10 Physical Dimensions

19.0” L x 6.6” W in x 2.25” D (not including external wiring and connections).

2.11 Weight

4.50 lb.

3 Address Description

AIM-9440 modules are addressable. The address is configured using a set of 8 dip switches labeled “Address” on the front panel (SW2 on the circuit board). Up to 256 unique addresses (0 thru 255) are settable.

ON 1 2 3 4 5 6 7 8

ADDRESS

Placing a switch in the “up” (on) position = logic “1”, and placing the switch in the down (off) position = logic “0”. In the example shown above, the 8 address switches from left to right are set to “10100010”. The least significant bit is on the left (switch #1) and the most significant bit is on the right (switch #8). Therefore the actual address of the AIM is “01000101” binary = 1+4+64 = address 69 decimal.

4 Connector Descriptions

Connections to ePAQ, and other AIM-9440 modules are by plug in connectors. The wording in bold indicates the front panel wording on the AIM-9440. The designations in parenthesis () indicate designations on the circuit board:

4.1 RS-422 Communications Ports

PORT 1A and PORT 1B (P1/P2): Communications port 1 -- Two RJ45 Connectors. This is a multi-drop RS-422 connection. The two connectors are in parallel with each other, to allow daisy-chaining from one AIM module to the next.

PORT 2A and PORT 2B (P3/P4): Communications port 2 -- Two RJ45 Connectors. This is a multi-drop RS-422 connection. The two connectors are in parallel with each other, to allow daisy-chaining from one AIM module to the next.

Only one comm port is required for communications with the ePAQ. Two communications ports are used exclusively for applications involving redundant communications with multiple ePAQs (see section 8 Typical Connections -- redundancy illustration).

Typically the communication port(s) on the AIM are connected to the ePAQ-9410 or ePAQ-9420 high-speed backbone ports 9, 10 and 11. These non-isolated ports on the ePAQ are intended for communication with the AIM, and other CGA I/O panels such as the SIM-9450 (Status Input Module) and COM-9460 (Control Output Module).

A typical installation would have an AIM module Port 1A connected to the ePAQ RS422 port #9 (or 10, or 11). AIM Port 1B is in turn connected to the next AIM module Port 1A, and so on. See the connection drawings.

Communication Port pinouts:

Connector Descriptions 5 Copyright © 2013 CG Automation USA Inc

Power for the AIM module logic circuitry is typically provided by the ePAQ through the communications line cable pins 1,2,7,and 8. For best performance, ensure that all four pins are used.

Note that the ePAQ RS422 communications lines (RS-422 ports 9, 10 and 11) that connect to the AIM are not meant for generic field connections, but are only meant for AIM (or SIM-9450 and COM-9460) modules located within same enclosure as the ePAQ.

4.1.1 RS-422 Termination

The RS-422 communications ports include pin socket connections for termination resistors (if required in the last daisy chained module, farthest from the ePAQ-94XX). For Port 1, these connections are labeled “R2” (for TX) and “R5” (for RX). For Port 2, they are labeled “R9” (for TX) and “R6” (for RX). The connections are directly below the four RJ45 jacks. The required termination resistors are 120 ohms 5% 1/2W axial leads (CGA P/N 10-055601-051 or equiv.)

To install the resistors, the blue module cover may need to be removed. Trim and insert the resistor leads firmly into the pin socket connections, then re-install the cover.

4.2 Field Wiring Connections

ANALOGS 1-32, TB1/TB2/TB3/TB4 (TB1/TB2/TB3/TB4): These are terminal blocks for field wiring of analog inputs. Each AIM has 64 terminal block connections to accommodate up to 32 analog inputs (two wires per input).

The terminal blocks are pluggable type. There are four sixteen position blocks.

There are two terminal block connections for each analog input.

PWR : Power. This LED indicates the state of the logic power supply. On = power is good. It is also located at the top left corner of the panel.

TX / RX : RS422 Transmit and Receive data for Port 1 and Port 2. Green (left) = data received by the AIM. Yellow (right) = data transmitted from the AIM. These LEDs are located on the RJ45 jacks for RS422 communications ports 1A/1B and 2A/2B (top right corner of the panel).

Earth Grounding Considerations 9 Copyright © 2013 CG Automation USA Inc

7 Earth Grounding Considerations

The AIM should be connected to a suitable earth ground connection on the system rack or cabinet. It is suggested to place a ring lug (with heavy gauge wire #14AWG min) and internal tooth lock washer under one of the mounting screws used to secure the AIM metal panel to the equipment rack.

10 Ordering Information

The AIM-9440 Analog Input Module (AIM) is a part of the CGA family of Distribution Automation Products. It is a microprocessor based electrical assembly, providing analog measurement capability to the ePAQ-94XX (ePAQ) products.

The AIM communicates with the ePAQ via a 4-wire RS-422 communications port. Each AIM can accept up to 32 analog measurement inputs (5Vdc, 10Vdc, 0-1mA, 4-20mA full scale) from connected field devices. Inputs are via 5mm plug-in type terminal blocks.

The AIM contains two RS-485 ports (4-wire) for redundant communications applications. Each port consists of two 8-pin RJ-45 jacks, allowing multi-drop communications for multiple AI modules on the same communications line.

Power input to the AIM is via pins on the RS-422 RJ45 jacks. Power is provided by the ePAQ backbone ports, or via a separate power supply. Input voltage is +24Vdc +/-20%.

Indicator LEDs are included for communications port TX/RX, heartbeat, and power.

The AI form factor is designed for mounting on a 19 inch equipment rack.
