📌 Product Description
The GE Simulator Panel is an industrial control and simulation assembly incorporating GE Mark VIe controller and I/O hardware. The listed assembly includes IS420UCSBH3A, IS420UCSBS1A, IS220PPDAH1B, and RXE2N0F7G132A. GE documentation identifies the IS420UCSBH3A as a UCSB controller and the IS420UCSBS1A as a Mark VIeS Safety Controller. The IS220PPDAH1A family is identified by GE as a Power Distribution System Feedback Module. These components are used within GE Mark VIe/Mark VIeS control architectures for control processing, safety control, I/O networking, and power-distribution feedback.
The complete panel can be useful for control-system simulation, engineering development, maintenance training, troubleshooting, system demonstration, and replacement-part evaluation. The exact function of the complete simulator assembly depends on its internal wiring, software configuration, terminal arrangement, and installed accessories.
