IC693MDL940L GE Fanuc 16-Point Relay Output Module 2A

Description

Product Introduction

The GE Fanuc IC693MDL940L is a 16-point relay output module for the Series 90-30 PLC platform. It is used to switch field loads such as indicators, solenoids, motor starters, and mixed AC/DC devices through relay contacts rather than transistor outputs.

Its practical advantage is load flexibility. A relay output card is the safe choice when one cabinet has mixed voltage needs or when the output must handle a field device that is not friendly to solid-state switching. In old 90-30 systems, that kind of flexibility still saves rework.

Key Technical Specifications

Application Scenarios & The “Trench” Experience

A relay output module usually fails in a way that looks deceptively small. One dead output, one stuck interlock, one starter that will not pull in, and suddenly the whole line is parked. In the field, the IC693MDL940L is the part you want when you need mixed-voltage switching without redesigning the output layer.

• Manufacturing – Starter and relay control – Used when the PLC must drive AC or DC field devices directly.
• Process control – Interlock outputs – Required for permissives, alarms, and hardwired control chains.
• Packaging lines – Mixed load switching – Needed when the same rack drives indicators, solenoids, and starters.
• Retrofit support – Legacy replacement – Chosen when the installed base already depends on relay contacts.

Field case: a packaging machine kept dropping a motor starter after intermittent contact wear on an old relay output card. The operator saw random stops, the electrician saw good voltage, and the real issue was the module. Swapping in a verified IC693MDL940L restored stable switching and avoided a deeper cabinet teardown.

Transparency SOP: Quality Assurance & Testing

We don’t just ship boxes; we test them on actual GE racks.

• Inbound Inspection: Check part number, suffix, relay housing, terminal condition, and label authenticity.
• Live Rig Testing: Install in a known-good Series 90-30 rack and verify all 16 outputs.
• Electrical Parameter Checks: Confirm contact closure, load switching, and isolation integrity.
• Firmware Verification: Not applicable in the normal sense, but hardware revision and relay response are logged.
• Final QC & Anti-static Packaging: Clean, test, and pack in ESD-safe materials before shipment.

The Veteran’s Tech Trap Guide

• ⚠️ Don’t assume relay means “anything goes.” It can switch mixed loads, but you still need to respect current and voltage limits.
• ❗ Watch the group limits. The module is rated 2 A per point, 4 A per common, and 16 A total. That is where people get burned.
• ⚠️ Contact wear is real. Relay modules age differently than transistor cards. Inductive loads shorten life fast.
• ❗ Check the suffix carefully. That last letter matters more than people think in old GE Series 90-30 stock.

Frequently Asked Questions (FAQ for Conversion)

A: No. Pulling it live is not a good idea. Power down first.

Q: Can it switch AC and DC loads?
A: Yes. That is one of the main reasons people still use it.

Q: How many outputs does it have?
A: 16 outputs arranged in four groups of four.

Q: What is the contact rating?
A: 2 A per output point, with common and total limits that must be respected.

Q: Is this a transistor output module?
A: No. It uses relay contacts, which is slower but far more flexible for mixed loads.

Q: Why is it cheaper than OEM direct supply?
A: Because most available stock comes from surplus channels, not active production.

Q: Is it fake or refurbished?
A: The surplus market is mixed. Good sellers should provide photos, test evidence, and revision details before shipment.
