GE PACSystems RX3i IC694MDL753B – 32‑Point 24 VDC Sourcing Output Module for High‑Density Discrete Control

The IC694MDL753B is a 32‑channel 24 VDC sourcing (PNP) output module for GE PACSystems RX3i. If you’re building a compact panel and need reliable, high‑density outputs for solenoids, contactors, lamps, and valve manifolds, this module hits a sweet spot. One thing I appreciate is how it groups channels for easier power distribution and fault isolation—handy when a single station on a packaging line misbehaves and you don’t want the whole zone going down. In many cases, it drops straight into brownfield RX3i expansions without rework.

Key Features

• 32-point 24 VDC sourcing outputs – Drives PNP loads; ideal for modern machine I/O standards in packaging, F&B, and intralogistics.
• Grouped power commons – Typically organized in groups (commonly 4×8), so a fault on one group doesn’t take out the rest.
• Compact, high-density – Frees rack space while keeping wiring clean; useful when cabinet depth is tight.
• Channel and group status LEDs – Quick fault localization without opening the HMI.
• Hot‑swap capable on RX3i – In most cases you can service the module under power to reduce downtime (follow site procedures).
• Robust 24 VDC output drive – Rated for industrial loads; from my experience, it handles inductive devices well when you add proper suppression.
• Seamless RX3i integration – Communicates over the RX3i backplane; configured with standard engineering tools.

Related or Supporting Products

• IC694MDL754 – 32‑pt 24 VDC sinking (NPN) output; choose this if your field devices expect sinking outputs.
• IC694MDL740 – 16‑pt relay output; mixed‑voltage loads or when you need galvanic isolation per point.
• IC695CHS012 / IC695CHS007 – RX3i baseplates (12‑slot / 7‑slot) commonly used with IC694 modules.
• IC695PSD040 – RX3i power supply; stable 24/5 VDC distribution for medium I/O counts.
• IC694TBB032 – 32‑point terminal block/carrier (commonly paired for neat field wiring and strain relief).

Installation & Maintenance

• Cabinet & environment – Install in an RX3i rack with adequate ventilation; keep clearance above/below the module and avoid heat sources. Typical ambient 0–60 °C.
• Wiring – Use appropriately rated 24 VDC field power with separate fusing per group. 0.5–1.5 mm² (20–16 AWG) conductors are commonly used. Add flyback diodes or RC snubbers on inductive loads.
• Grounding & noise – Bond shield drains at one end only; route I/O cables away from VFD and high‑current lines.
• Hot swap discipline – The module supports hot insertion on RX3i, but I typically place outputs in a safe state and isolate field power before removal.
• Routine checks – Inspect terminals for looseness, verify LED status per channel, and review fault logs in the controller. Keep controller/module firmware at a supported revision.
• Spare strategy – Many plants keep a spare on the shelf due to the module’s role in machine interlocks; it minimizes mean time to repair.

Quality & Certifications

• CE, UL/cUL; RoHS compliant on most later revisions (the “B” hardware revision typically aligns with current compliance).
• Manufacturer quality system aligned with ISO standards for industrial automation.
• Company warranty: 365 days. Units are function-tested before shipment; DOA replacement support is available.
