The Technobox P/N 5658 ECM module provides eight channels of 12 bit current measurement in the 0 to 25 milliamp range.

For each channel the common mode voltage range is -100 volts to +100 volts.

Each channel uses a precision 100 ohm current sense resistor, creating a voltage drop of 2 V in the current loop at 20 milliamps. The current should be unidirectional however as shown in the application section.

Maximum data rates are 100KHz, but samples per channel will depend on the number of channels scanned, if all eight channels are scanned the rate per channel would be 100KHz / 8 = 12.5 KHz.

Each of the current sense resistors can carry a maximum of 25 milliamps. Also the current flow should always be from the odd numbered IO signal to the even numbered IO signal.

PositiveVoltageapplication, Apply up to +100 volts to the odd numbered IO signal in the case of a positive voltage current loop.
