GE Fanuc Series 90-30 IC693MDL733 12/24VDC 0.5A Positive Logic 8-Point Output Module

Module Overview

The IC693MDL733 is a high-reliability discrete output module specifically designed for the GE Fanuc Series 90-30 PLC family. It features eight independent output points grouped into a single bank, utilizing positive logic (sourcing) circuitry. This module is the standard choice for interfacing with mid-range DC field devices such as indicator lights, small relays, and low-power interposing circuits where a 0.5A current capacity is required per channel.

Detailed Technical Specifications

The IC693MDL733 operates by sourcing current from the user-supplied power terminal to the connected load. It is designed to withstand the rugged environments typical of industrial control cabinets while maintaining precise switching timing.

Application and Integration Notes

Engineers selecting the IC693MDL733 should ensure that the cumulative load for all eight points does not exceed the 2.0A module limit, especially in high-temperature environments. While each point can handle 0.5A individually, concurrent activation of all points requires thermal management. This module is frequently used in legacy migration projects where Series 90-30 hardware must remain operational under the Emerson automation umbrella.

Functional Comparison: IC693MDL733 vs. IC693MDL732

While both modules serve as DC output components for the Series 90-30, they cater to different electrical requirements:

• IC693MDL733: Positive Logic (Sourcing). Current flows from the module to the load.

• IC693MDL732: Negative Logic (Sinking). The load is connected to the positive supply, and the module completes the path to ground.

Engineering FAQ

What happens if a field-side short circuit occurs?

The IC693MDL733 is equipped with internal fuses to prevent damage to the backplane and neighboring modules. If a fault occurs, the fuse will interrupt the circuit, necessitating a diagnostic check of the field wiring before replacement.

Does this module require external power?

Yes. While the logic side is powered by the PLC backplane (50 mA draw), the field-side devices require an external 12/24 VDC power supply connected to the module’s terminal block.
