GE IC693MDL741C – 32-Point Discrete DC Output Module | Series 90-30 Platform
Engineering Background
The IC693MDL741C is a high-density discrete output module designed for GE’s Series 90-30 programmable logic controller platform — one of the most widely deployed mid-range PLC families in industrial automation. The Series 90-30 architecture has been a backbone of manufacturing, utilities, and process control installations globally for over three decades, making replacement and expansion modules like the IC693MDL741C critical procurement items for maintenance engineers managing long-lifecycle assets.
Product Positioning
This module addresses the need for reliable, high-channel-count discrete output capability within the Series 90-30 rack. With 32 individually addressable output points at 24VDC, it is suited for driving solenoids, relays, indicator lamps, and other field devices in demanding industrial environments. Konmask.com supplies this module as a genuine, quality-verified component with full traceability documentation available on request.

Engineering Advantages
- High Channel Density: 32 output points in a single slot minimizes rack space consumption and reduces wiring complexity versus lower-density alternatives.
- Optical Isolation: Protects the CPU backplane from field-side voltage transients and ground loops — essential in electrically noisy industrial environments.
- Hot-Swap Compatible: Supports module replacement without full system shutdown when used with appropriate Series 90-30 rack configurations.
- Revision C Stability: The “C” firmware/hardware revision incorporates GE’s accumulated field feedback, offering improved reliability over earlier revisions.
- Direct CPU Addressability: Fully addressable via GE Proficy Machine Edition (ME) and legacy Logicmaster 90 programming environments.
- Long-Lifecycle Platform Support: Compatible with the broad installed base of Series 90-30 systems, extending asset life without full system replacement.
System Architecture & Signal Flow
The IC693MDL741C occupies a standard I/O slot in any Series 90-30 baseplate. The CPU communicates with the module via the Series 90-30 backplane bus, writing output data to the module’s internal register map. Each of the 32 output channels is driven by an optically isolated transistor output stage. Field wiring connects to the module’s removable terminal block (RTB), which accepts standard 18–22 AWG conductors. The module draws logic power from the backplane and field power from the user-supplied 24VDC field power bus. Fusing of field power is the responsibility of the system designer per applicable electrical codes.

Technical FAQ
Q: Is the IC693MDL741C sourcing or sinking output?
A: The MDL741 series is a sourcing (PNP) output module. Verify the specific revision label on the unit for confirmation, as GE released both sourcing and sinking variants in the IC693 output module family.
Q: Can this module replace an IC693MDL741A or IC693MDL741B?
A: In most cases yes — the C revision is backward compatible with earlier revisions in the same slot. However, always verify with your GE Series 90-30 hardware manual (GFK-0356) before substitution in safety-critical applications.
Q: What programming software is required?
A: GE Proficy Machine Edition (ME) Logic Developer PLC is the current supported programming environment. Legacy Logicmaster 90-30 software is also compatible for older CPU revisions.
Q: Is a removable terminal block (RTB) included?
A: RTB inclusion depends on stock condition. Please confirm at time of order. Compatible RTB part number: IC693ACC300 (36-pin RTB for 32-point modules).
Q: What is the lead time for out-of-stock units?
A: Typical sourcing lead time is 5–15 business days for non-stocked units. Contact support@konmask.com for current availability and expedite options.
Q: Do you provide MSDS / RoHS documentation?
A: RoHS compliance documentation is available for applicable revisions. Contact support@konmask.com with your order reference to request compliance certificates.
