Product Overview
The GE IC697VAL324 Analog Output Module is an industrial analog output module engineered for the GE Fanuc Series 90-70 PLC platform. It provides a reliable interface between the PLC controller and field devices that require continuously variable analog control signals, enabling accurate and stable regulation of industrial processes.
As part of the Series 90-70 distributed I/O family, the IC697VAL324 converts digital output values generated by the PLC CPU into proportional analog electrical signals. These signals are used to control compatible field equipment such as variable frequency drives (VFDs), proportional control valves, valve positioners, servo controllers, dosing systems, industrial actuators, and other analog-controlled devices. By enabling continuous rather than discrete control, the module helps improve process accuracy, equipment efficiency, and overall system stability.
The module installs directly into a Series 90-70 PLC rack and communicates with the controller through the high-speed backplane. During operation, the PLC continuously calculates output values based on operator commands, process measurements, production recipes, or PID control algorithms. The IC697VAL324 accurately converts these values into analog signals that regulate field equipment in real time.
The module is suitable for a wide range of industrial sectors including manufacturing automation, water and wastewater treatment, oil and gas production, chemical processing, power generation, pharmaceutical manufacturing, HVAC systems, mining, food and beverage production, and other applications requiring dependable analog process control.
With compact dimensions of 200 × 40 × 150 mm and an approximate weight of 1.36 kg, the IC697VAL324 provides an efficient rack-mounted solution for industrial control cabinets.
