Product Introduction
The is a 16-point relay output module in the VersaMax I/O family, originally developed by GE Fanuc and now part of the Emerson automation portfolio. It provides sixteen individually isolated Form A (normally open) relay contacts, allowing each channel to switch independent AC or DC loads — ideal for solenoid valves, motor starters, contactor coils, alarm horns, and status indicators.
Why this matters: relay output modules are often the last link between the PLC and field devices. A failed channel can leave a valve stuck, a contactor un-energized, or an alarm silent. The “F” suffix indicates a specific revision within the IC200MDL940 family, so matching it against your existing module label is important for consistent behavior. These modules are discontinued and increasingly difficult to source in unused condition.

Key Selling Points & Differentiators
- Correct VersaMax relay output module. Designed for GE/Emerson VersaMax PLC and NIU systems — not compatible with IC693, IC695, IC697, or other PLC families.
- 16 individually isolated Form A contacts. Each channel can be wired to a different voltage source, simplifying mixed AC/DC load applications.
- No output leakage current. Dry relay contacts mean zero leakage when open — important for sensitive loads and safety circuits.
- Wide voltage coverage. Supports both AC and DC loads from low-voltage DC control circuits to 240 VAC power circuits.
- New surplus availability. Discontinued GE module. We stock verified, unused units — not pulled modules with unknown relay cycling history.
- Not recommended for high-speed switching, PWM loads, or applications requiring Form C (changeover) contacts.
- 12-month warranty with pre-shipment visual inspection and connector verification.
Quality Transparency SOP
- Label & suffix audit. Verify “IC200MDL940F” on the module label. Confirm the “F” suffix matches the existing module.
- Visual PCB inspection. Check for burnt relay housings, cracked solder joints, swollen capacitors, or corrosion around terminal blocks.
- Connector & terminal check. Verify all backplane and field-side connectors are straight, clean, and undamaged. Confirm the locking/unlocking lever operates smoothly.
- Contact continuity check. Test each relay contact for proper open/closed state with a multimeter. Confirm no welded or stuck contacts.
- ESD packaging. Sealed in anti-static bag, foam-padded box, shipped with a signed inspection report.
Technical Risk Avoidance
- ❗ Match the full suffix. IC200MDL940, IC200MDL940A, IC200MDL940F, and other suffix variants may differ in revision or manufacturing lot. Replace like-for-like unless engineering approves otherwise.
- ❗ No internal snubbers or fuses. The module does not include built-in surge suppression or per-channel fusing. External RC snubbers (AC) or flyback diodes (DC inductive loads) and external fusing are strongly recommended.
- ❗ Respect the 2 A per-channel limit. For inductive loads (solenoids, contactor coils), stay well below the 2 A resistive rating and limit switching to 20 cycles/min.
- ❗ DC derating above 30 VDC. Some references indicate reduced current capacity at higher DC voltages. Confirm derating requirements from the official hardware manual before switching high-voltage DC loads.
- ❗ Do not use for high-speed switching. With a 10 ms response time and mechanical relay life limits, this module is unsuitable for fast pulsing or PWM applications.
- ❗ Verify external load power wiring. The module switches load circuits via external power supplies. Incorrect wiring can energize the wrong field device.
Buyer’s FAQ
Q: What system is IC200MDL940F used in? A: It is used in GE/Emerson VersaMax PLC and NIU systems as a 16-channel isolated relay output module.
Q: Is the same as IC200MDL940? A: They share the same base part number. The “F” suffix indicates a specific revision. Always match the full part number on your existing module before ordering.
Q: Can it switch both AC and DC loads? A: Yes. It supports 0–265 VAC and 0–125 VDC, with each channel individually isolated so different channels can use different voltage sources.
Q: Does it have Form C (changeover) contacts? A: No. It provides Form A (normally open) contacts only.
Q: Does it include internal fuses or snubbers? A: No. External fusing and surge suppression must be provided by the system designer.
Q: Is this new or refurbished? A: New original surplus — factory sealed, never installed. We do not sell pulled or refurbished modules as “new.”
Q: What’s the lead time and warranty? A: In-stock units ship within 1–2 business days. 12-month warranty from ship date, covering manufacturing defects and DOA failures.
