GE-FanucIC600BF923KSeries Six 32-Point Sink Output Module, 10-50 V DC, 5 V DC Backplane, 2000 V DC Isolation, 0-60 C

Product Description

What this part is

A GE Fanuc Series Six high-density discrete output module: 32 output points, current-sinking type, switching DC loads in the 10 to 50 V range. It plugs into a Series Six or Series Six Plus I/O rack, draws its logic power from the 5 V DC backplane, and drives solenoid valves, contactor coils, indicator lamps and interposing relays under PLC control. This is a digital on/off output card — it is not an analog output module and it has no inputs.

What these specs mean in practice

Sink versus source is the single detail that decides whether this card works in your panel. A sinking output completes the circuit to the negative rail: the load sits between the positive supply and the output point. If the existing field wiring is built for a sourcing card, dropping this module in will not switch anything and can look like a dead card. Check the wiring convention on the module you are replacing before ordering.

32 points in one slot is why these cards were specified — density. It also means one card failure takes 32 outputs with it, so a spare on the shelf is cheap insurance on a machine that cannot come down. The 180 mA current rating and 1 mA off-state leakage are what set the load type: interposing relays, solenoid valves and pilot lamps yes, motor loads no. That off-state leakage is also worth knowing if you are driving a very high-impedance electronic input, which can read the leakage as an on-state.

Quantity and configuration

Sold as one output module.

What is not included

Module only. No I/O rack, backplane or card cage. No field wiring terminal board, terminal block assembly or wiring harness — confirm you have the matching terminal assembly for your rack. No rack power supply, CPU or logic module. No I/O control module or local I/O transmitter/receiver. No documentation, and no programming terminal or software.

Installation and setup notes

Power the rack down before insertion and observe ESD precautions. Note the slot address, because Series Six I/O references are slot-dependent and moving a card changes the addresses the ladder sees. Verify field supply polarity and that the load voltage sits inside 10 to 50 V DC. When commissioning, force points individually before returning the machine to automatic; a wiring convention error shows up immediately that way rather than as an unexplained sequence fault.

Interchange guidance

IC600BF923K, IC600BF923, IC600 BF 923K and IC600BF-923K all refer to this card; the trailing letter is the hardware revision. IC600BF902 is a 24 V DC sink output with 8 points, IC600BF929 is a high-density 10–50 V DC source card, and IC600BF943 is a 4–20 mA analog output — all related Series Six cards, none of them substitutes for a 32-point sink output. Series Six I/O is proprietary to GE Fanuc racks and has no cross-brand equivalent; it is also not interchangeable with the later Series 90-30 (IC693) or VersaMax families.
