Converts six RTD or resistance inputs with an integrating 16-bit A/D converter.
Key Information
HE693RTD600R identifies revision R of the Horner HE693RTD600 resistance-temperature input module for the GE Fanuc Series 90-30 platform. The manufacturer revision table places revision R and earlier on Series 90-30 only; later revisions add RX3i platform support.
The module accepts multiple platinum, copper and nickel RTD curves plus a linear resistance range. Each of the six channels occupies one %AI reference and can be configured for the required sensor type.
Functions
Supports platinum, copper, nickel, linear-resistance and TD5R sensor selections documented by Horner.
Provides zener-diode clamp input fault protection and high input impedance.
Tracks channels closely for multi-point temperature acquisition inside one rack module.

Installation
- Verify the physical label ends in R and keep the destination to a Series 90-30 rack; do not infer RX3i support from later HE693RTD600 revisions.
- Export the six-channel sensor-type selections, engineering units, resolution and alarm scaling.
- Record two-, three- or four-wire field arrangements from the installed drawing and preserve shield and grounding practice.
- Inspect the terminal assembly and field resistance before transferring conductors; an open, shorted or mismatched lead can imitate a module fault.
- After replacement, compare every channel against a traceable resistance or temperature source at more than one point.
Lifecycle
- Store the HE693RTD600R revision in the spare record rather than only HE693RTD600.
- Retain calibration checks, sensor curves and lead-wire arrangements with the PLC backup.
- Use the documented Horner scaling and diagnostic behavior when rebuilding the logic interface.
- Trend all six channels after restart to expose common wiring or reference errors.

FAQ
Can HE693RTD600R be moved directly into an RX3i rack?
The Horner specification states revision R and earlier support Series 90-30 only; later revisions add RX3i support, so this R unit should not be assumed compatible.
What is the most important backup before replacing HE693RTD600R?
Capture each channel’s RTD curve, engineering units, resolution, wiring method, alarms and %AI scaling.
Why might all HE693RTD600R channels shift together after replacement?
Common terminal, grounding, shield, reference or configuration errors can affect multiple channels even when individual sensors are healthy.
How should a spare HE693RTD600R be bench-checked?
Use traceable resistance standards appropriate to the configured curves and compare multiple points on all six channels after warm-up.
What label evidence should accompany an HE693RTD600R enquiry?
Provide the full front and side labels showing HE693RTD600R, rack position, terminal assembly and any calibration or asset markings.
