GE IC693MDL741E – 16-Point 24V DC Output Module

This output module controls DC field devices from the Series 90-30 PLC system. It drives solenoids, relays, indicator lamps, and small contactors reliably. You can install this unit alongside analog or specialty modules in any rack.

Key Technical Specifications

Physical Layout and Rack Mounting

This output module measures 127 mm in width and 89 mm in height. Its depth reaches 56 mm for standard Series 90-30 racks. The unit weighs 275 grams, allowing easy one-hand installation. Two locking levers secure the module firmly into its chassis slot.

Internal Circuitry and Energy Storage

Ninety-eight components populate this double-sided output board. An 1800 µF capacitor bank provides snubbing for inductive load switching. This bank absorbs back-EMF energy from solenoids and relays effectively. Consequently, the module protects output transistors from damaging voltage spikes. Each output includes a dedicated optocoupler for complete bus-to-field isolation.

Output Configuration and Wiring Details

Sixteen sink-type (NPN) outputs switch the DC common side of your loads. You connect the positive supply to your device, then wire the return to an output terminal. Each channel handles up to 0.5 amps continuously without external heat sinking. The total module current cannot exceed 4 amps across all active points. A removable terminal block accepts wires from 0.2 mm² to 1.5 mm² cross-section.

Protection Features and Diagnostics

Short-circuit protection shuts down an individual output within 100 microseconds. The module automatically resets that channel after removing the fault condition. Over-temperature protection reduces current limit when internal temperature exceeds 85°C. Sixteen green LEDs show the on-off state of each output point clearly. Therefore, you can troubleshoot field wiring without connecting a programming terminal.
