Overview
Configured for 32-channel discrete output control in the Series 90-30 PLC platform, the GE Fanuc Emerson IC693MDL753 (IC693MDL753 discrete output module) provides direct electrical switching through four groups of eight output points. Each point supports 12-24 VDC nominal operation, with a maximum output current of 0.5 A per point.

Backplane and Output Circuit Characteristics
The IC693MDL753 receives its module supply through the Series 90-30 backplane and draws 260 mA from the 5 VDC backplane supply. Meanwhile, the field side provides 32 discrete output points arranged as four groups of eight.
Each output point can switch up to 0.5 A, while each group supports up to 4 A. The common connection has a stated maximum current of 3 A. Therefore, field wiring should account for both individual point loading and the aggregate current within each output group.
The supplied data also specifies an ON-state consumption of 3 mA + 3 mA per point ON, together with 4.7 mA for each LED indicator. These values describe additional module-side current requirements associated with output and status indication.
Frequently Asked Questions
Q: How many output channels does the IC693MDL753 provide?
A: The module provides 32 discrete output points divided into four groups, with eight channels in each group.
Q: What current can each IC693MDL753 output point handle?
A: Each output point supports up to 0.5 A. The stated maximum is 4 A for each eight-channel group.
Q: How much current does the module draw from the PLC backplane?
A: The module draws 260 mA from the 5 VDC Series 90-30 backplane supply.
Field Installation Guidelines
Install the IC693MDL753 in a compatible Series 90-30 PLC rack and verify that the module is correctly seated in the backplane connector before applying power.
Size field wiring according to the connected load and the stated 0.5 A per-point and 4 A per-group limits. Keep the total current through each common connection within the specified 3 A maximum.
Route discrete output wiring separately from high-energy power conductors where practical. Secure conductors at the terminal points and avoid loose connections that can introduce intermittent output behavior.
Before energizing the field circuit, verify the external supply polarity, output group connections, load ratings, and common wiring against the control cabinet drawings. Also confirm that the connected loads remain within the specified output voltage and current ranges.
