The IC694MDL940 output module is a GE Fanuc 16-point relay output module. This output controller module is used with the RX3i PACSystems modules. It is powerful and is available with several useful features. It is used for controlling output loads. It has a current rating of 2 Amps for output switching. It is a RX3i series module and it is manufactured for industrial use. It is powered with a voltage rating of 24 Volts DC or 120/240 Volts AC. The number of outputs is 16 and they are arranged in 4 groups. The operating frequency for the AC voltage supply is 50/60 Hertz. The output voltage range lies between 5 and 30 Volts DC or 5 and 250 Volts AC. It has a current consumption rating of 7 milliamps with 5 Volts bus voltage, and 135 milliamps with 24 Volts relay voltage. 


The front of the IC694MDL940 output module has LED indicators to show the on/off status of each output point. No fuses are present in this high-voltage module. An isolation voltage of 250 Volts AC is present between the field and frame and there is an isolation voltage of 1500 Volts AC between the backplane and frame ground in the IC694MDL940 output module. The module can take a maximum load of 2 Amps of pilot duty current per output and a load of 4 Amps maximum per common. The minimum load required is 10 milliamps and the maximum inrush current rating is 5 Amps. The IC694MDL940 output module can be configured by using the Proficy Machine Edition programming software. The operating temperature should be set between 0 and 60 degrees Celsius.
