IC693MDL740E 12/24VDC 0.5A 16-Point Positive Logic Output Module for Series 90-30 PLC

This discrete output module provides 16 positive-logic sourcing outputs for compatible Series 90-30 PLC systems. The outputs are divided into two isolated groups of eight, with each point rated for up to 0.5A and each group limited to 2A through its common power terminal.

The module is designed for user-powered 12/24VDC field devices such as motor starters, contactor coils, solenoids, relays, pilot lights, and indicators.

Interchangeable / Replacement Part Numbers

Base catalog and documented revision levels:

IC693MDL740, IC693MDL740A, IC693MDL740B, IC693MDL740C, IC693MDL740D, IC693MDL740E, IC693MDL740F, IC693MDL740G, IC693MDL740H, IC693MDL740J, IC693MDL740K, IC693MDL740L

These suffixes identify hardware or production revisions within the same IC693MDL740 electrical catalog family. They are normally configured in the PLC project as IC693MDL740 and provide the same basic 12/24VDC positive-logic 16-point output function.

⭐➕ Optional Terminal Block Quick-Connect Components

The standard module uses its removable 20-position terminal board. An optional DIN-rail Terminal Block Quick-Connect system may be used when all matching components are installed:

• Compatible TBQC Terminal Block: IC693ACC330
• Required 24-Pin Module Faceplate: IC693ACC334
• 0.5-Meter Cable: IC693CBL334
• 1-Meter Cable: IC693CBL330
• 2-Meter Cable: IC693CBL332

Obsolete cable cross-reference:

• IC693CBL323 is replaced by IC693CBL334
• IC693CBL321 is replaced by IC693CBL330
• IC693CBL322 is replaced by IC693CBL332

⚙️ Fit and Installation Notes

• This is a positive-logic sourcing module. Each load must be wired between the applicable module output and the negative field-power bus.
• A separate 12/24VDC field-power source is required. The PLC backplane does not supply power for the connected loads.
• The module contains no internal fuses and no electronic short-circuit protection. Provide correctly rated external circuit protection.
• Observe the 0.5A per-point and 2A per-common limits.
• Total permissible module load decreases at elevated ambient temperatures. Follow the published load-current derating curve.
• Check the starting or inrush current of solenoids, contactors, lamps, and other inductive loads.
• Install appropriate suppression across inductive DC loads when required by the equipment design.
• Turn off both rack power and external field power before installing, removing, or rewiring the module.
• Do not install or remove the module while energized.
• Confirm that the removable terminal board matches the original wiring before applying power.
• The CPU slot on a modular CPU baseplate cannot be used for this output module.
• Configure the replacement under the base catalog number IC693MDL740.
• Similar-looking negative-logic, 1A protected, 32-point, or IC694-family modules should not be substituted solely because the connector or front housing appears similar.
