GE-FanucSeries Six Reed Relay Output Module, 6-Point Dry Contact, Single Slot

Product Description

What this part is

A GE Fanuc Series Six Reed Relay Output Module, catalogue number IC600BF914K. It is a discrete output module for the Series Six I/O rack, and it switches loads through reed relay contacts rather than through a solid-state transistor or triac. The published module count is six output points.

Decoding the order code

IC600: GE Fanuc Series Six product line. BF: board with faceplate. The same circuit board supplied bare is the YB914 and the faceplate alone is the FP914, so BF914 is board plus faceplate as one saleable assembly. 914: Reed Relay Output, per the GE Fanuc Series Six module catalogue. K: revision suffix. A unit with an equal or higher alpha suffix is a direct replacement for one with a lower suffix, so a K supersedes A through J.

Reed relay outputs against solid-state outputs

A reed relay output is a set of voltage-free mechanical contacts, with no leakage current when off, no minimum load, and no fixed rail voltage in the module. Each point wires to the load it serves, AC or DC, and different points can run different voltages. That suits interposing relays, contactor coils, annunciator lamps, chart recorders, instrument inputs and any load a triac’s off-state leakage would falsely trigger. Contact life is finite, switching speed is slower than solid state, and inductive loads take a snubber or freewheel diode across the coil.

Published specifications

Direct replacement for lower-suffix IC600BF914 modules. IC600YB914 is the same circuit board without a faceplate and is a related item. The other Series Six 9xx output modules are different output technologies: BF921 and BF923 are 24 V and 48 V DC sink outputs, BF924 is 115 V AC, BF929 and BF930 are 115 V and 230 V AC isolated, BF941 is a 0 to 10 V DC analog output.
