IC693ALG223 is a PACSystems Series 90-30 RX3i Analog Current Input Module that offers 16 channels.
The module’s 16 separate and single ended channels can be configured for any of the following three ranges: 4 to 20 mA, 0 to 20 mA, or 4 to 20 mA Enhanced. Both high and low alarms are obtainable on each range. In the enhanced range, the IC693ALG223 module can be set with a low alarm limit to detect input current with open wire fault detection in the 4 to 20 mA applications; high alarm alerts can also be set by the user.
Additionally, this module reports status, including power supply standing to the CPU. IC693ALG223 can be used in any I/O slot that offers a serial connector in the RX3i or Series 90-30 system.
Specific to the IC693ALG223 module, 120 mA from a 5 VCD bus on the controller backplane is consumed. This also needs a 65 mA plus current loop from a +24 VDC supply supplied by the user. An update rate of 6 ms is standard with isolation of 250 VAC continuous or 1500 VAC for one minute.
When scanning active channels, the number of channels to be scanned will be completed in serial order. Analog values are scaled over the entire range of the converter with factory calibration adjusting the analog value per bit.
RX3i racks support upgrades to the firmware associated with this module, but this does not include 90-30 racks.
The IC693ALG223 is also equipped with LED status lights emitting ON, OFF, and FAIL to assist the user in operation and troubleshooting.
