GE PACSystems RX3i IC694MDL740 – 12/24 VDC 16‑Point Digital Output Module for Reliable Discrete Control

The GE IC694MDL740 is a 16-point 12/24 VDC digital output module for PACSystems RX3i racks. From my experience, it’s a straightforward pick when you need clean, deterministic switching for solenoids, pilot lamps, contactor coils, and small DC actuators. You might notice that it supports positive or negative logic, so it can be applied in both sourcing and sinking schemes without redesigning your wiring concept. Two isolated groups of 8 points help segment loads and simplify troubleshooting, and front LEDs make it easy to see what’s actually switching in the cabinet.

• Payment: 50% advance payment; full payment before delivery
• Express options: FedEx, UPS, DHL

Key Features

• 16 × 12/24 VDC outputs – Practical channel count for machine cells, conveyors, and compact OEM panels.
• Positive/negative logic (sourcing/sinking) – Typically lets you wire to PNP or NPN field devices without changing hardware.
• Two groups of 8 – Grouped commons help separate critical loads from general outputs; easier maintenance too.
• Front status LEDs per point – Quick visual checks during commissioning and fault recovery.
• RX3i backplane integration – Configured via the RX3i CPU (e.g., Proficy Machine Edition), no extra interface cards.
• Compact, single‑slot module – Keeps cabinet real estate tight, with tidy wiring via the removable terminal block.
• Industrial operating range – Designed for typical shop-floor environments with stable performance.

Technical Specifications

Where it fits best

Common uses include machine tools, packaging lines, intralogistics, and process skids that need dependable DC output switching. One thing I appreciate is how quickly technicians can isolate a wiring issue with the grouped commons and the LEDs — it saves hours. A maintenance lead at a food plant told us this module “dropped into the RX3i rack and took over a 16‑valve manifold with zero fuss.”

Installation & Maintenance

• Cabinet & mounting – Install the module in an RX3i rack (panel‑mounted). Keep ventilation clear; avoid mounting near high‑heat sources or VFDs without shielding.
• Wiring – Use a clean 12/24 VDC field supply sized for the total load. Separate high‑inductive loads into their own group when possible, and add flyback suppression across coils.
• Grounding & noise – Maintain a single‑point ground and route I/O wiring away from high‑frequency power cables. Shielding helps in noisy bays.
• Commissioning – Verify logic polarity (sourcing vs. sinking) in the project, then check each LED against the expected state before going live.
• Routine care – Inspect terminals for looseness, clean dust quarterly, and keep firmware and project backups aligned with change control. No regular calibration is required.
• Safety – De‑energize field power before servicing; lockout/tagout in accordance with plant procedures.

Quality & Certifications

• Built to recognized industrial standards; typically CE, UL/cUL, and RoHS compliant for RX3i modules.
• Manufacturer warranty practices align with PACSystems guidelines; we support a 365‑day warranty on supply.

Notes: Specifications can vary slightly by firmware revision and rack configuration. If you’re replacing an existing output card, send a photo of the label and we’ll confirm compatibility before shipment.
