GE Fanuc IC694ALG392 Analog Output Module

The GE Fanuc IC694ALG392 is an analog output module for the PACSystem RX3i series. It provides eight single-ended output channels that can generate various signal types, including both voltage and current outputs. These outputs are ideal for modulating control in systems that require continuous, variable control of processes, such as in industrial automation and process control applications.

Technical Specifications

Update Rate

• Update Rate: 8 milliseconds (all eight channels)

Calibration

• Factory Calibration:
  • 0.625 µA for 0 to 20mA
  • 0.5 µA for 4 to 20mA
  • 0.3125 mV for voltage (per count)

Power Requirements

• User Supply Voltage: 20 VDC to 30 VDC (nominal 24V DC)
• Power Consumption:
  • 110 mA from the 5V DC PLC backplane supply
  • 315 mA from the 24V DC external user supply

Isolation and Protection

• Isolation (Field to Backplane and to Frame Ground):
  • 250 VAC continuous
  • 1500 VDC for 1 minute

Environmental Considerations

• Protection: Environmental protection must be provided by the user, as the module has a low IP rating and is sensitive to moisture and extreme temperature variations.

Compatibility

• Compatible Actuators: Valves, motors, pistons, and agitators
• Supported PLCs: GE Fanuc Series 90-30 and 90-70

• Weight: 0.66 lbs
