I/O modules

The GE IC600BF914K relay output module provides robust discrete switching capabilities for Series Six programmable logic controllers. This module features sixteen individually isolated relay outputs, each rated for 2 amps at 250 VAC or 30 VDC. Each output channel includes a dedicated status indicator for immediate visual confirmation of the switching state. The GE IC600BF914K also offers normally open and normally closed contact configurations for flexible control applications. This relay module excels in environments requiring isolation between control and field power, protecting sensitive PLC backplane circuits.

Hardware Architecture and Technical Specifications

The GE IC600BF914K incorporates sixteen electromechanical relays arranged in four groups of four channels. Each relay coil draws approximately 20 milliamps from the 24 VDC power source. The module includes surge suppression circuits across each relay coil to minimize electrical noise generation. The IC600BF914K also provides fuse protection for each output channel against overcurrent conditions. Its terminal block accepts wire sizes from 14 to 22 AWG for secure field connections. The module’s printed circuit board contains a single semiconductor output driver chip and optoisolation circuitry. A 50-pin ribbon cable connects the module to the Series Six backplane for communication with the CPU.

The physical dimensions of the GE IC600BF914K measure 12.0 inches in height and 2.5 inches in width. The depth extends to 8.0 inches, fitting standard Series Six rack configurations. This module weighs approximately 3.2 pounds, reflecting the robust construction of its relay components. The front panel features a clear labeling scheme for easy identification of each channel and its corresponding terminal positions. The IC600BF914K operates reliably across a temperature range from 0 to 60 degrees Celsius without derating.

Operational Characteristics and Application Benefits

This relay output module responds to discrete commands from the CPU with a typical response time of 10 milliseconds. The electromechanical relays offer a mechanical life exceeding 10 million operations at no load. Each contact exhibits a maximum resistance of 100 milliohms for minimal voltage drop during switching. The GE IC600BF914K supports both AC and DC load switching, providing exceptional versatility for diverse machine control tasks. Users can replace individual relays on the module for economical field repairs.
