IC693MDL760B GE 16-Point 24 VDC Sourcing Output Module

Product Overview of the IC693MDL760B

The IC693MDL760B is a 16-point discrete output module from the GE Fanuc Series 90-30 platform. Originally manufactured by GE Fanuc and now owned by Emerson, this module provides 24 VDC positive logic sourcing outputs. Consequently, it suits control panels that must drive relays, solenoids, and indicator lamps directly from the PLC backplane. Each output handles 0.5 A at 30 VDC, so the module covers a broad range of industrial loads without external interposing hardware.

IC693MDL760B Technical Specifications

• Output Points: 16 sourcing, arranged in two groups of eight
• Output Voltage Range: 18 to 30 VDC
• Output Current: 0.5 A per point at 30 VDC
• On Response Time: 12 ms maximum
• Backplane Current: 75 mA maximum from 5 V bus
• Operating Temperature: 0 to +60°C ambient
• Storage Temperature: -40 to +85°C
• Humidity: 5 to 95% non-condensing
• Protection Rating: IP20
• Dimensions (H×W×D): 124 × 30 × 114 mm

The 12 ms maximum on response time is a distinctive parameter. In practice, it bounds how quickly a field device energizes after a logic command, which matters in sequencing and interlock circuits. Meanwhile, the 75 mA backplane draw at full output load keeps power budgeting predictable for the rack.

Failure Mode Analysis for Discrete Output Modules

Output modules in continuous service typically degrade through three mechanisms. First, output driver failure occurs when inductive loads generate reverse voltage spikes at turn-off. Second, connector and terminal corrosion develops in humid or contaminated environments. Third, thermal stress accumulates when ambient temperature approaches the 0 to +60°C limit. Because the IC693MDL760B sources current rather than sinking it, a shorted field wire can hold an output permanently energized. Therefore, verify field wiring insulation periodically and confirm that each load current stays within the 0.5 A per point rating at 30 VDC.

Installation and Integration Notes

This single-slot module occupies one slot in a Series 90-30 rack. It draws 75 mA maximum from the 5 V backplane bus with all outputs energized, so include that figure in rack power calculations. The IP20 rating means the module requires a clean, protected enclosure; it does not tolerate dust or water ingress. For field connections, follow the terminal assignments in the official GE Fanuc documentation. In addition, confirm that the external 24 VDC supply stays within the 18 to 30 VDC output voltage range under all load conditions.

Lifecycle and Availability

The IC693MDL760B is listed as legacy/obsolete in aftermarket channels, and the official Emerson end-of-service date is not verified. This part belongs to a discontinued platform (GE Series 90-30), superseded by PACSystems RX3i (IC695 series). We stock remaining new and refurbished units. For teams maintaining existing Series 90-30 installations, sourcing verified modules remains essential to avoid unplanned downtime.
