The IC694MDL645 is a part of the RX3i PACSystems module series by GE Fanuc Automation. This 16-Point Input Module has 16 input channels in one group and the module is rated for a nominal voltage of 24 Volts DC. The operating input voltage range of the module is from zero (0) to 30 Volts DC. The IC694MDL645 input module is a low voltage RX3i PACSystems module and is marked as a low voltage module with a blue label. The input current rating of the module is 7 milliamperes and the current consumption ratings are 80 milliamperes of current at 5 Volts DC bus voltage and 125 milliamperes at 24 Volts DC supply voltage. All 16 input points of the module support either positive or negative logic.

The operating temperature range of the IC694MDL645 input module is zero (0) to 60 degrees Celsius or 32 to 140 degrees Fahrenheit while the optimum storage temperature range is -40 to 85 degrees Celsius or -40 to 185 degrees Fahrenheit. The input module needs to be used and stored in an environment that is non-condensing but humid. For its safe storage and operation, the tolerable humidity level is from 5 to 95%. The IC694MDL645 can be installed in an RX3i PACSystems PLC or can be easily removed from it while the PLC is powered on as long as the field side terminal is not connected. This input module can be installed in any slot available in the backplane of the RX3i PACSystems PLC.

The IC694MDL645 input module is part of the RX3i family of PACSystems modules made by GE Fanuc. This module runs at a 24 Volts DC nominal voltage and features 16 inputs grouped together. It operates between 0 and 30 Volts DC. The IC694MDL645 input module is intended to be a low-voltage RX3i PACSystems module, as shown by the blue label included with it. The IC694MDL645 input module has an input rated current of 80 milliamperes at 5 Volts DC Bus voltage and a current consumption value of 125 milliamperes at 24 Volts DC voltage source. Each of the module's sixteen inputs supports logic, either positive or negative. The IC694MDL645 Input Module by GE Fanuc features sixteen green LEDs that indicate whether the module's sixteen input points are active or inactive. This module operates at a low voltage, as indicated by the presence of two blue bands at the bottom side of the module's top label.
 IC694MDL645 Input Module features a wide range of input parameters, including an on-state voltage rating between 11.5 and 30 Volts DC, and voltage at off-state between  0 and 5 Volts DC, a minimum on-state current rating of 3.2 milliamperes, a maximum off-state current of 1.1 milliamperes, an 7 milliseconds average on-state response time, and also an average off-state of 7 milliseconds response periods. 
The GE Fanuc RX3i PACSystems IC694MDL645 input module operates between 32 and 140 degrees F / 0 and 60 ° C, while the module stores data at -40 to 185 ℉ / -40 to 85 ℃. This input module should be housed and utilized in somewhat humid but non-condensing conditions. For safe operation and storage, the IC694MDL645 input module's acceptable humidity tolerance is 5% to 95%. This module can be put in or removed securely from an RX3i PACSystems PLC while the PLC is switched on, as long as the module's field side terminal is not attached. The IC694MDL645 input module might be positioned in any available slot on the backplane of the RX3i PACSystems PLC.
