Product Introduction & Supply Chain Strategy
The GE Fanuc IC660EBR101 is a 16-point relay output block in the Genius I/O architecture. It provides isolated relay contacts to interface programmable controllers with external motors, solenoids, and high-voltage actuators across distributed plant networks.
Because GE Fanuc discontinued the Genius I/O platform, sourcing this module as New Surplus protects critical infrastructure from extended downtime. Securing factory-sealed units reduces Total Cost of Ownership (TCO) compared to high-risk refurbished options while bridging last-time-buy gaps.
Installation & Configuration Guide
Stage 1: Pre-Installation (Prep & Safety)
Perform Lock-Out/Tag-Out (LOTO) on all field power circuits supplying the relay contacts. Attach an ESD grounded wrist strap before touching the module. Document or photograph DIP switch settings, node addresses, and terminal connections on the underlying base unit.
Stage 2: Removal
Loosen the top and bottom mounting screws on the existing electronics module. Pull the module straight out from the terminal block assembly, ensuring no uneven torque bends the internal backplane interface pins.
Stage 3: Installation (Clone & Seat)
Verify that the replacement IC660EBR101 DIP switches match the original node configuration and bus parameters. Align the module track with the terminal block housing and press firmly until the connectors lock. Torque securing screws to 0.8 Nm.
Stage 4: Power-On & Testing
Apply logic supply voltage and observe the front-panel LEDs. Confirm the “PWR” and “BUS” indicators show solid green. Force test relay channels individually using the controller programming software to verify field contact switching.

Firmware/Software Versions & Upgrade Notes
- Recommended Firmware: Hardware Revision 4.0 or higher provides full compatibility with legacy Series 90-30, Series 90-70, and PACSystems RX3i controllers utilizing Genius Bus Controller (GBC) interfaces.
- Compatibility Constraints: Must pair with standard Genius I/O relay terminal block assemblies (such as IC660TBR101). Serial communication baud rate must match all other nodes on the Genius bus segment (153.6 kbps standard).
- Upgrade Risks: Avoid upgrading block firmware on live networks. Unmatched firmware across redundant Genius blocks can trigger bus handshaking timeouts or reset controller scan routines.
Frequently Asked Questions (FAQ)
1. Is this IC660EBR101 module brand new or pulled from working equipment?
This product is a Brand New Surplus unit. It is not used, not pulled from a decommissioned plant, and not refurbished. All modules undergo rigorous quality verification to ensure OEM-level reliability.
2. Why should our plant avoid buying refurbished IC660EBR101 blocks?
Refurbished relay modules frequently suffer from hidden contact degradation, dried electrolytic capacitors, and weakened relay coil armatures. A chemical plant recently tried to save procurement budget by buying a refurbished DCS I/O module. Three months later, it failed, causing a reactor temperature fault and an emergency shutdown. The downtime cost was 10x what they “saved.”
3. Is the Genius I/O system officially discontinued by the OEM?
Yes, GE Fanuc (now Emerson) has formally retired the Genius I/O platform. Because OEM production has ceased, plant managers must secure critical spares through strategic buffer stock from reputable New Surplus distributors.
4. Do I need to re-wire my terminal block when replacing an IC660EBR101 unit?
No. The Genius I/O system uses a two-piece design separating the field wiring base from the electronics assembly. You can replace the electronics block without disconnecting any field wiring on the terminal block.
5. How do I configure the node address on a new block?
Node addressing is set via DIP switches or programmed through a Hand-Held Monitor (HHM). Ensure the replacement unit matches the precise node ID of the former unit before re-connecting to the active serial bus.
6. Can this module be hot-swapped while the Genius bus is live?
While the electronics block can technically be unseated from the terminal assembly without powering down the entire serial bus, best practice requires isolating field load power before extraction to prevent arc flash or output jitter.
7. What warranty coverage applies to this New Surplus module?
Every New Surplus comes backed by a comprehensive 1-2 year replacement warranty, offering full operational assurance compared to the typical 30-day coverage provided on used or refurbished parts.
