IC694ALG223 high-density analog Input module GE

IC694ALG223

The IC694ALG223 has internal current draw of 120 mA from the 5VDC bus voltage and 65 mA including the individual current of each current loop which is powered by an external 24 VDC supply voltage.

The IC694ALG223 input module is a 16-channel analog current input module from GE Fanuc and the RX3i PacSystems series. There are 16 single-ended input channels on the IC694ALG223 input module. Three input ranges can be configured for each of the input channels through the configuration software, and these ranges are 0 to 20 milliamps, 4 to 20 milliamps (enhanced), and 4 to 20 milliamps (normal). High and low alarm thresholds can be set for all input ranges. For the 4 to 20 milliamps enhanced input range, an alarm can be set to detect an input current ranging from 4 to 0 milliamps and this provides open-wire fault detection for 4 to 20 milliamps rated applications. The IC694ALG223 input module is capable of providing power supply status and module status updates to the system CPU. The IC694ALG223 input module can be installed in I/O slots of Series 90-30 PLC systems that have a serial connector.

The current requirement of the IC694ALG223 input module is 120 milliamps at 5 Volts DC. The IC694ALG223 input module also draws 65 milliamps of current-loop currents from an external +24 Volts DC power supply. For the 4 to 20 milliamps current range, the factory calibration is 4 microamps per count, and for the 0 to 20 milliamps and the 4 to 20 milliamps enhanced ranges, the factory calibration is 5 microamps per count. The update rate for the IC694ALG223 module is 6 milliseconds. The common mode voltage is 0 volts for single-ended channels. The common mode rejection is greater than 70 decibels for DC voltage at up to 1 kilohertz. The input impedance for the IC694ALG223 input module is 250 Ohms. The input low pass filter response is 19 Hertz. The voltage range for the external voltage supply is from 20 to 30 Volts DC.
