Description
The GE Fanuc IC697VAL318 is a high-performance, isolated analog output module engineered for the Series 90-70 PLC platform. This module is designed to bridge digital control logic and physical field devices by providing eight independent current loop output channels. It is widely utilized in demanding industrial applications, including power generation, chemical processing, and water management, where precise control of actuators, valves, and drives is essential for process stability.
Features
-
Eight Independent Channels: Provides eight isolated 4 to 20 mA output signals for multi-loop control applications.
-
Galvanic Isolation: Includes robust isolation between channels and the PLC backplane to mitigate ground loops and protect against electrical noise or surges.
-
High-Resolution Output: Features 12-bit resolution to ensure fine-grained control and accuracy for critical process instrumentation.
-
Field-Replaceable Design: Equipped with a removable terminal block to allow for simplified maintenance and faster field wiring replacement without disturbing existing cable runs.
Applications
This module is specifically suited for controlling industrial equipment that requires reliable 4 to 20 mA current signals. Common use cases include the positioning of pneumatic valves, the regulation of variable frequency drives (VFDs), and the sending of setpoints to remote process controllers in large-scale automation architectures.

-
Slot Alignment: Verify that the module is correctly aligned with the backplane connector before applying pressure to seat the unit into the Series 90-70 rack.
-
Cooling: Maintain adequate clearance around the module to ensure proper airflow and heat dissipation within the cabinet.
FAQ
Is the IC697VAL318 compatible with all Series 90-70 racks?
Yes, this module is designed for standard Series 90-70 PLC backplanes. Ensure your rack has the appropriate slot configuration for an analog output module.
Does this module require external power for the current loops?
The module is designed to operate within the 4 to 20 mA standard; please refer to your specific loop power requirements for the field devices being controlled.
Can I replace the terminal block without rewiring the entire system?
Yes, the IC697VAL318 features a removable terminal block, which allows you to disconnect the wiring interface from the module without needing to remove individual wires from the terminals.
