GE IC610MDL157B Sink Output Module

The GE Fanuc IC610MDL157B, also cataloged as the IC610MDL157 24 VDC Sink Output Module, operates as a dedicated hardware component for discrete DC load switching within GE Fanuc Series One controller platforms. The module routes logic-level commands from the central backplane to driving external 24 VDC field loads via current-sinking output transistors, providing direct electrical switching execution for industrial solenoids, relays, and indicator circuits.

Hardware Specifications

Deterministic Network and I/O Density Scaling

The IC610MDL157B output card maintains deterministic backplane bus communication velocity across the Series One chassis backplane, synchronizing output bit updates directly with the CPU scan cycle. Designed for modular I/O density scaling, the circuit topology prevents signal cross-talk and field voltage backfeeding into logic components. Full firmware flash compatibility across backplane interface chips ensures stable execution of discrete control algorithms without introducing response lag to physical outputs.

Frequently Asked Questions

Q: How is the current-sinking circuit executed on the IC660/IC610MDL157B output points?

A: The output channels utilize NPN transistor switches that complete the circuit by connecting the load to the 24 VDC supply common when activated.

Q: Does the IC610MDL157B module require external field power to energize output loads?

A: Yes, while logic power is drawn from the backplane bus, an external 24 VDC field supply must be wired to drive connected field devices.

Q: Can the IC610MDL157B output card be hot-swapped while the rack is powered?

A: No, system power to the rack chassis must be isolated prior to removing or inserting the module to prevent backplane bus damage.

Field Installation Guidelines

1. De-energize cabinet supply power and field circuit voltage sources before inserting or removing the module.
2. Align the IC610MDL157B with the designated chassis slot rails of the Series One base rack and press firmly until fully seated.
3. Wire external 24 VDC field power and loads to the removable terminal block following correct sinking polarity.
4. Ensure the cabinet protective earth (PE) grounding lug connects securely to the chassis ground rail to suppress electrical noise.
5. Maintain separation between low-voltage DC output wiring and high-voltage AC power conductors in panel wireways.
