Description
Product Introduction & Engineering Value
Not every control system requires high-current output modules. Many industrial applications simply need dependable switching for standard 24 VDC loads while maintaining straightforward troubleshooting and proven long-term reliability.
The GE IC693MDL740 is a 16-point positive logic DC output module for the Series 90-30 PLC platform. It sources power to field devices, supports two isolated output groups, and offers individual LED diagnostics for every channel. The module is commonly used for machine automation, conveyor systems, packaging equipment, and general process control where standard DC outputs are required.

Field Application & The “Trench” Experience
A bottling facility experienced intermittent production stops after several relay outputs failed on an aging PLC output card. The field wiring and solenoid valves tested correctly, but several outputs could no longer source sufficient current under load.
Maintenance technicians replaced the module with an IC693MDL740, verified every output using the machine’s manual mode, and completed startup within a single maintenance window. Since the existing wiring remained unchanged, the replacement required minimal downtime and no PLC program modifications.
Typical application scenarios include:
- Pneumatic valve manifold control on packaging equipment
- Conveyor motor starter and contactor control
- Process skid indicator lamps and alarm annunciation

Transparency SOP: QA & Testing
Every output module is evaluated before shipment using a documented functional test procedure.
- Verify part number, hardware revision, and terminal integrity.
- Inspect the PCB, backplane connector, housing, and LED assembly.
- Install the module in a Series 90-30 test rack.
- Apply rated loads to all 16 output channels.
- Verify output voltage, current capacity, response time, and LED operation.
- Confirm communication with the PLC CPU during repeated power cycles.
- Package the module in ESD-safe protective materials for industrial transportation.
New Surplus inventory is inspected to confirm unused condition. Refurbished units undergo additional load testing and extended operational verification.
The Veteran’s Tech Trap Guide
⚠️ This Is a Sourcing Output Module
The IC693MDL740 uses positive logic (sourcing) outputs. If your field devices are wired for sinking outputs, the module will not operate correctly without rewiring the output circuit.
⚠️ Watch the Group Current Limit
Each group of eight outputs shares a 2 A common current limit. Individual outputs may be rated for 0.5 A, but exceeding the common current rating can overheat the module and shorten its service life.
PRO TIP: When several outputs switch inductive loads simultaneously, install properly rated flyback diodes or suppression devices on DC coils. This greatly reduces voltage transients and extends output transistor life.
⚠️ No Internal Fuse Protection
The module does not include built-in output fuses. External branch circuit protection should be provided according to the load requirements and applicable electrical standards.
Dynamic FAQ
Q1. What is the primary function of the IC693MDL740?
The module provides 16 positive logic DC outputs for controlling external devices such as relays, contactors, solenoids, pilot lights, and other 12/24 VDC loads.
Q2. How much current can each output supply?
Each output supports up to 0.5 A, while each common output group is limited to 2 A total. Proper load distribution is recommended.
Q3. Can the IC693MDL740 be installed in any Series 90-30 baseplate?
Yes. The module can be installed in any available I/O slot on compatible 5-slot or 10-slot Series 90-30 baseplates.
Q4. Does the module include output diagnostics?
Yes. Every output channel has an individual green LED that indicates the commanded output status, simplifying commissioning and troubleshooting.
Q5. Which field devices are commonly controlled by this module?
Typical applications include solenoid valves, motor starters, relay coils, indicator lamps, alarm beacons, and pneumatic actuators operating from 12 or 24 VDC control power.
Q6. Are New Surplus modules tested before shipment?
Yes. New Surplus modules are inspected for unused condition, part number verification, connector integrity, and cosmetic quality. Refurbished units additionally undergo full-channel load testing, output verification, communication checks, and repeated power-cycle testing before shipment.
