Product Overview
The GE IC697VDR151 Relay Output Module is a high-performance Relay Output Module designed for the GE Fanuc Series 90-70 PLC platform. It provides dependable relay-based output switching for industrial automation systems, allowing the PLC processor to control a wide variety of AC and DC field devices through electrically isolated relay contacts. Designed for demanding industrial environments, the module delivers reliable switching performance, high system availability, and long-term operational stability.
As a member of the Series 90-70 I/O family, the IC697VDR151 installs directly into a compatible PLC rack and communicates with the CPU through the high-speed backplane. The PLC executes the user control program and sends digital output commands to the relay module. The IC697VDR151 energizes or de-energizes its internal relay contacts, controlling connected devices such as motor starters, contactors, solenoid valves, indicator lamps, alarm devices, pumps, fans, and other industrial equipment.
The relay-based output design provides excellent electrical isolation between the PLC electronics and field circuits, making the module suitable for mixed-voltage AC and DC control applications. Its rugged industrial construction ensures reliable operation under conditions involving electrical noise, vibration, temperature fluctuations, and continuous production cycles.
Typical applications include manufacturing automation, conveyor systems, packaging machinery, water treatment facilities, chemical processing plants, power generation, mining operations, oil and gas installations, pharmaceutical production, food and beverage processing, and material handling systems.
With compact dimensions of 200 × 40 × 150 mm and an approximate weight of 1.36 kg, the IC697VDR151 integrates easily into standard Series 90-70 control cabinets.
