Digital Remote Indicator Page 1/3 April 2008

• The Digital Remote Indicator, IDR 144, is micropocessed product that can be used both as master (for link to digital transducer) and slave (for link for link to RTU, net, etc).

• (1) RS 485 Serial Interface Modbus RTU is Standard, the second serial interface RS485 is optional.

• Frontal keyboard with tactile feedback. • 3 LCDs displays alphanumeric 1 line 16 characters. • Simultaneous indication of 3 voltages (U12, U23, U32) and 3

currents (I1, I2, I3), in the first reading screen. • Simultaneous indication of Active Power (Pt), Reactive Power

(Qt) and frequency (f), in the second reading screen. • Others screens: preview of others electrical variables as:

voltage line-neutral (UN1, UN2, UN3) active, reactive and apparent power for phase (P1, P2, P3, Q1, Q2, Q3, S1, S2, S3), and total (Pt, Qt, St), power factor for phase and total (FP1, FP2, FF3, FPT), angular delay for phase and total (A1, A2, A3, At), active and reactive energy, consumed and supplied energy (Wh+, Wh-, Varh+, Varh-), current demand for phase (DI1, DI2, DI3), active, reactive and apparent total power demand (DPT, DQT, DST), frequency (f).

• Non volatile memory to store data of RTP, RTC, IDR address in the net, transmission rate and byte format.

• Auxiliary power supply universal AC/DC • Protection: IP50 (Housing) and IP20 (terminal connection). • Reading resolution: 0,01% . • Processing resolution : 16 bits. • Software parameterization. • Phases indication : blue (1), white (2) and red (3). Technical Data (NBR 8145) Display Type Liquid crystal display (LCD) (1) line and (16) characters Number of Display s (3) independents, alphanumeric.

View behind the equipment

Obs.: All the configurations can be made by keyboard except of the Tag, that only can be configured through IBIS-BE-cnf software.

Additional Information The following items contain tips and cautions to be observed by the user for a good functional performance, as well as the maintenance of the instrument and the safety of the installations.

Cautions Be sure that the voltage to be connected to the instrument are compatible

Assembly Instructions Observe the ambient temperature range. At the place of installation, values for vibration, dust, dirt and humidity, which must remain between the limits, established by the protection class of the housing and the climatic group, specified in this data sheet, have to be observed. For mounting on DIN rail, use the snap-in device on the rear of the instrument. The connections can be made with pin for shaped cable shoes, for the input signals in Voltage and Current and for the Auxiliary Power, RS485 and digital outputs terminals type pin.
