IC200ERM001C GE VersaMax Isolated Expansion Receiver Module

The GE IC200ERM001C, also cataloged as the IC200ERM001 Isolated Expansion Receiver Module, operates as a dedicated hardware component for multi-rack I/O bus expansion and signal isolation within GE VersaMax control platforms.

Hardware Specifications

Backplane Bus Communication Velocity & Deterministic Network Execution

The IC200ERM001C receives isolated expansion bus signals from an upstream expansion transmitter module (such as the ETM001) via its top 26-pin D-shell port. It rebuilds and routes local backplane voltage levels between 3.3 VDC and 5 VDC to power downstream I/O and communication modules installed on the expansion rack, optimizing backplane bus communication velocity across long distances.

The bottom female 26-pin D-shell port enables daisy-chain connections to subsequent expansion racks or accommodates an expansion bus terminator plug on the final node. Full integration into Profinet / EtherNet/IP deterministic network topologies is maintained through the primary controller interface, while strict firmware flash compatibility ensures synchronized scan execution and low-latency protocol passthrough across all extended racks.

Frequently Asked Questions

Q: What is the functional role of the rotary switch located on the IC200ERM001C module?

A: The rotary switch located under the front access door sets the unique hardware address (Rack ID) for the specific expansion rack within the system topology.

Q: How are the two 26-pin female D-shell ports utilized on the expansion receiver module?

A: The top D-shell port receives the expansion cable from the upstream transmitter or preceding receiver, while the bottom port daisy-chains to the next expansion rack or houses a bus termination plug on the final rack.

Q: Can the IC200ERM001C module be removed or inserted while the expansion rack power supply is energized?

A: No. All incoming power sources to the expansion rack and primary controller must be de-energized prior to removing or installing the module to prevent electrical damage to the expansion bus.

Field Installation Guidelines

1. Power Shutdown: De-energize and lock out all power sources feeding the host system and the expansion rack backplane prior to installation or maintenance.
2. Rack Position: Mount the IC200ERM001C module exclusively in the far-left slot position of the VersaMax expansion rack on the 35 mm DIN rail.
3. Address Configuration: Set the onboard rotary switch to the assigned expansion rack ID number prior to securing the module onto the backplane carrier.
4. Cable Interconnection: Secure the 26-pin expansion cable from the upstream transmitter into the top D-shell port using integrated thumbscrews. Attach a daisy-chain cable or terminal plug to the bottom D-shell port.
5. Electrostatic Discharge (ESD): Wear a grounded anti-static wrist strap attached to the enclosure metallic earth during installation to protect onboard IC logic from static damage.
