GE IC660BBR100 Replacement for Genius I/O Series

Product Overview

GE IC660BBR100 Replacement for Genius I/O Series: Smooth Migration & Legacy System Upgrade

The GE IC660BBR100 is a 16-point normally-closed (NC) relay output block designed for the GE Fanuc Genius I/O distributed I/O platform. As GE Fanuc’s Genius I/O series approaches end-of-life and spare parts become increasingly scarce, many plant engineers and system integrators are actively seeking a reliable, drop-in replacement that preserves existing wiring infrastructure, minimizes reprogramming effort, and reduces unplanned downtime. TOPNLMS supplies the IC660BBR100 as a direct replacement module, fully tested and backed by a 12-month warranty, ready to ship from our Xiamen warehouse to global destinations.

Whether your facility is running a legacy Series 90-70 PLC, a Series 90-30 controller, or a standalone Genius Bus architecture, the IC660BBR100 integrates seamlessly into the existing Genius Bus network without requiring changes to the bus controller configuration or the Genius Bus Interface Unit (GBIU). The module communicates over the Genius Bus serial protocol at 153.6 Kbaud, maintaining full compatibility with existing IC660BBA020 bus controllers and IC660CBB900 Genius Bus cables already installed in the field.

Seamless Upgrade Solutions

A successful migration from a legacy Genius I/O system to a modernized architecture typically involves more than swapping a single output block. During the upgrade process, engineers commonly address the entire I/O subsystem to ensure long-term supportability. The IC660BBR100 is frequently deployed alongside the IC660BBA020 Genius Bus Controller, which manages bus arbitration and handles communication between the host PLC and all field devices on the Genius Bus segment. Where analog signals are present, the IC660BBD020 16-Point DC Input Block and IC660TBD024 terminal assembly are often replaced in the same maintenance window to standardize the I/O platform across the panel.

For facilities transitioning from Series 90-70 to a VersaMax or PACSystems RX3i architecture, the Genius Bus remains a supported legacy interface through the IC693BEM331 Genius Bus Controller module installed in the VersaMax rack. This allows the IC660BBR100 to continue operating on the existing bus while the host controller is upgraded, dramatically reducing the scope and risk of the migration project. Power distribution within the control cabinet is typically handled by a IC693PWR321 24VDC Power Supply or equivalent, which feeds both the Genius Bus and the relay output loads without requiring additional power conditioning.

Where communication protocol modernization is required — for example, migrating from Genius Bus to PROFIBUS-DP or EtherNet/IP — a Genius Bus-to-PROFIBUS gateway or a VersaMax PROFIBUS Scanner (IC200PBI001) can bridge the legacy field devices to the new network backbone, preserving the IC660BBR100 investment while enabling Industry 4.0 connectivity. Signal isolation between the relay outputs and sensitive instrumentation loops is commonly achieved using Phoenix Contact or Weidmüller DIN-rail signal isolators, which are physically compatible with the same panel layout.

For programming and commissioning, the IC690ACC901 Hand-Held Monitor (HHM) or the Proficy Machine Edition programming software with a IC690USB901 USB programming cable allows engineers to verify block configuration, monitor I/O status, and adjust datagram assignments without taking the bus offline. HMI integration is typically handled through a QuickPanel+ or Cimplicity SCADA connection to the host PLC, with no changes required to the Genius I/O field wiring.

Retrofit Guidance FAQ

Q: Can I replace the IC660BBR100 without rewiring the terminal block?
A: Yes. The IC660BBR100 uses the same 40-pin removable terminal block as other Genius I/O relay output blocks. The terminal assembly detaches from the electronics module, so the field wiring remains undisturbed during the swap. Simply remove the terminal block from the old module, slide it onto the replacement unit, and restore power.

Q: Do I need to reprogram the PLC after replacing this block?
A: In most cases, no. The IC660BBR100 retains the same Genius Bus device type and datagram structure as the original block. The host PLC — whether a Series 90-70 or Series 90-30 — will recognize the replacement module automatically after a bus scan. If the block’s reference address or datagram configuration was customized, verify the settings using the Hand-Held Monitor or Proficy Machine Edition before returning the system to production.

Q: Is the IC660BBR100 compatible with both Series 90-70 and Series 90-30 PLCs?
A: Yes. The Genius Bus protocol is consistent across GE Fanuc’s Series 90 PLC family. The IC660BBR100 operates identically whether the bus controller is an IC693BEM331 in a VersaMax rack or an IC697BEM731 in a Series 90-70 rack.

Q: What is the physical installation space requirement?
A: The IC660BBR100 occupies the standard Genius I/O block footprint (approximately 180 mm × 100 mm × 60 mm). It mounts on a standard 35 mm DIN rail or can be panel-mounted using the existing mounting holes. No additional panel cutouts or bracket modifications are required for a like-for-like replacement.

Q: What communication protocol does this module use?
A: The IC660BBR100 communicates exclusively over the GE Genius Bus serial protocol at 153.6 Kbaud. It is not natively compatible with PROFIBUS, DeviceNet, or EtherNet/IP without an external gateway. If protocol migration is required, a Genius Bus gateway module should be evaluated as part of the upgrade plan.

Q: Can this module handle mixed AC/DC load switching?
A: The relay contacts on the IC660BBR100 are rated for both AC and DC loads, making it suitable for mixed-voltage control cabinet applications. Verify the contact current rating against your specific load requirements before installation.

Warranty Assurance

Every GE IC660BBR100 unit supplied by TOPNLMS is covered by a 12-month warranty from the date of shipment. Prior to dispatch, each module undergoes functional verification including bus communication testing, relay contact continuity checks, and visual inspection for physical damage. Units that do not pass our pre-shipment test protocol are not shipped.

In the event of a confirmed defect within the warranty period, TOPNLMS will arrange a replacement shipment or issue a refund based on the customer’s preference. Our after-sales response target is within 24 business hours of a warranty claim submission. Replacement units are dispatched from our Xiamen warehouse with priority shipping to minimize production impact.

For procurement teams requiring documentation, we can provide a test report, packing list, and commercial invoice with each shipment. Export compliance documentation for cross-border shipments is available upon request. Bulk orders and long-term supply agreements are supported with lead-time commitments and reserved stock arrangements.
