Remote I/O Expansion Solution – GE HE693RTM705 | Series 90-30
Where This Product Is Used
The GE HE693RTM705 Remote Terminal Module is engineered for industrial environments where distributed I/O is essential. Typical deployment scenarios include:
- Automotive Assembly Lines – Extends PLC control to remote tooling stations and conveyor endpoints without additional CPUs.
- Oil & Gas Processing Plants – Connects remote field instruments and actuators back to a central Series 90-30 controller over long cable runs.
- Water & Wastewater Treatment – Manages distributed pump stations and valve banks from a single PLC rack.
- Food & Beverage Production – Integrates remote filling, capping, and labeling stations into a unified control architecture.
- Power Generation & Utilities – Provides reliable remote I/O connectivity in high-noise electrical environments.
- Discrete Manufacturing – Supports multi-zone machine control where I/O points are physically separated from the main control panel.

Application-Specific FAQ
Q: Can the HE693RTM705 be used with GE PACSystems RX3i racks?
A: No. The HE693RTM705 is designed exclusively for the GE Series 90-30 remote I/O bus architecture and is not compatible with PACSystems RX3i or RX7i backplanes.
Q: How many remote drops can a Series 90-30 CPU support?
A: Depending on the CPU model, the Series 90-30 supports up to 7 remote I/O drops. Consult your CPU datasheet for the exact limit.
Q: Is programming required when replacing an HE693RTM705?
A: Typically no. The RTM is a bus interface module; replacing it with an identical unit does not require PLC program changes, only correct rack addressing.
Q: What cable type is required for the remote I/O bus?
A: GE specifies shielded twisted-pair cable per the Series 90-30 Remote I/O Installation Manual (GFK-0898). Maximum cable length depends on baud rate selection.
Q: Do you provide a warranty?
A: Yes. Konmask.com provides a 90-day functional warranty on all tested units. Extended warranty options are available upon request.
