The IC694MDL231 input module has an input frequency in the range of 50 to 60 Hertz. For isolation, the field to backplane voltage is 250 Volts AC continuous, and the isolation voltage to the frame is 1500 Volts AC for a time period of 60 seconds. The on-state voltage of the module is set between 148 and 264 Volts AC, whereas the offset voltage lies between 0 and 40 Volts AC. The IC694MDL231 input module consumes 60 milliamps of current from the bus on the backplane of the module. The backplane bus has a voltage rating of 5 Volts. The front of the module has 8 LED indicators for each of the 8 points. The LED indicators show the on and off status of the input points. The IC694MDL231 input module is compatible with the RX3i PLC system. The temperature of the installation area should be between 0 and 60 degrees Celsius.
