Description

Hardware & Electrical Specifications

‑ Model：IC693MDL940 ‑ Part Number：IC693MDL940 ‑ Module Type：Series‑90‑30 16‑Point Relay Output Module ‑ Mounting：Plug‑in onto any I/O slot of Series‑90‑30 backplane ‑ Backplane power consumption：  • 5VDC bus：7 mA (all outputs ON)  • 24VDC relay drive bus：135 mA (all outputs ON) ‑ Output channel：16‑point NO normally‑open relay output, 4 groups ×4 points ‑ Load voltage range：  • DC：5‑30 VDC  • AC：5‑250 VAC, 50/60Hz ‑ Load current：  • Per‑channel resistive max：2 A  • Per‑group common terminal max：4 A  • Minimum load current：10 mA  • Peak inrush current：5 A max ‑ Response time：ON max 15 ms; OFF max 15 ms ‑ Isolation：  • Field‑to‑logic backplane：1500 VAC 1‑minute withstand  • Between output groups：500 VAC isolation  • No isolation between points inside same group ‑ Terminal：Removable screw‑type terminal block ‑ PCB treatment：Conformal coated for dust‑moisture‑corrosion resistance ‑ On‑board feature：No internal channel fuse; external fuse required for field loop protection ‑ Compatibility note：Cannot run standalone; install in Series‑90‑30 base rack; inductive loads need free‑wheel diode / RC absorption circuit; full discrete‑loop simulation test mandatory after replacement。

Environmental Specifications

‑ Operating temperature：0 ℃ ~ +60 ℃ ‑ Storage temperature：‑40 ℃ ~ +85 ℃ ‑ Relative humidity：5%‑95% non‑condensing ‑ Installation location：Indoor industrial control cabinet, IP20 ‑ EMC compliance：IEC 61000‑6‑2 ‑ Certifications：CE, UL Class I Div 2 hazardous‑location certification

Mechanical Data

‑ Weight：approx 0.40 kg ‑ Dimension：Series‑90‑30 standard single‑slot module form‑factor ‑ Handling note：ESD‑sensitive relay drive circuit, anti‑static wrist‑strap mandatory during handling; inductive loads must add absorption protection

Main Functions

1. Control field‑side solenoid valves, contactors, indicator lamps, motor starter auxiliary coils and other AC/DC loads via relay contact outputs.
2. Receive output data from Series‑90‑30 CPU through backplane bus, drive relay contacts to switch external field power circuit.
3. LED status indication:   ‑ Green PWR：Module internal power‑on indicator   ‑ 16 individual channel green LEDs：Real‑time status of each output point ON/OFF

Installation & Wiring Requirements

1. Cut off PLC rack power and field‑side external load power before replacement. Hot‑swap is forbidden. Strict anti‑static protection when handling module.
2. Insert IC693MDL940 fully into PLC backplane slot and lock latch.
3. Field wiring strictly follow GE Series‑90‑30 hardware manual; for inductive loads (coil, contactor), install RC‑snubber or free‑wheel diode absorption components; add external fuse for each group output; separate output cables from high‑power cables, connect shielding to protective ground terminal.
4. Complete protective grounding according to GE system specification.
5. After replacement：power‑on rack, verify PWR and channel LED status; perform full‑channel output trigger test.
6. Replacement note: Calculate group current not to exceed 4A per‑common limit; inductive load absorption protection is mandatory; full system commissioning test mandatory before unit put‑into‑service.
