Emerson IC694MDL742B PACSystems RX3i 16-Point 12/24 V DC Positive-Logic Output Module
A sixteen-point positive-logic DC output module with electronic short-circuit protection and the B revision retained.
Product Identification
IC694MDL742B is the B hardware revision of the Emerson PACSystems RX3i IC694MDL742 discrete output module. The base module provides sixteen 12/24 V DC positive-logic outputs rated at 1 A with electronic short-circuit protection.
The B revision, terminal assignment, group power and field-load schedule must remain together. Adjacent IC694MDL74x modules differ in polarity, output current and protective behavior, so selection by family number alone is insufficient.
The B revision preserves the installed hardware baseline for this protected sixteen-point positive-logic output module.

FAQ
What distinguishes IC694MDL742B from IC694MDL741?
The MDL742 base is a 1 A positive-logic module with electronic short-circuit protection; nearby modules have different polarity or ratings.
What should accompany a IC694MDL742B enquiry?
Provide the B label, rack slot, terminal schedule, group supply and load current/inrush information.
Does ESCP eliminate the need for circuit review on IC694MDL742B?
No. Field protection, wiring capacity, suppression and load behavior still need engineering review.
Can the B revision be ignored when selecting a spare?
No. Retain it and verify the project and installed hardware baseline before substitution.
What proves IC694MDL742B is ready after replacement?
Document correct module recognition and successful operation and diagnostics for each active output.
