Product profile

Function, System Position and Selection Boundary

The three modules sense DC field states and provide front status indication, but their electrical and mechanical boundaries differ. Selection must use the complete number, not only the 24 VDC family label.

IC655MDL501 and IC655MDL502 are negative-logic modules with 16 and 32 points. IC655MDL503 provides 64 points of 24 VDC positive/negative logic and uses high-density front connectors rather than the removable screw terminal block used by the lower-density modules.

Series Five DC input comparison

Point Density Changes the Wiring Method

The 64-point IC655MDL503 cannot be treated as a denser drop-in version of the terminal-block modules. Harness, connector, polarity and reference planning all change.

IC655MDL501

Two groups of eight; field-serviceable terminal block.

IC655MDL502

Four groups of eight; 32-point terminal block.

IC655MDL503

Eight groups of eight; two front connectors and A–D/E–H LED selection.

Replacement workflow

Installation and Acceptance Sequence

Confirm point count, logic direction and connector/terminal style.
Save the starting I/O reference and label every group common.
Transfer wiring or the exact harness with power removed.
Test all points and use LED/address mode to confirm the configured start reference.

Model-specific questions

FAQ

Which electrical role is shared by IC655MDL501 / IC655MDL502 / IC655MDL503?

They are Series Five DC input modules with front status indication and configurable I/O references.

Which of IC655MDL501 / IC655MDL502 / IC655MDL503 supports positive and negative logic?

IC655MDL503 is the 64-point 24 VDC positive/negative-logic model.

How do point counts differ across IC655MDL501 / IC655MDL502 / IC655MDL503?

IC655MDL501 has 16 points, IC655MDL502 has 32 and IC655MDL503 has 64.

Do IC655MDL501 / IC655MDL502 / IC655MDL503 use the same field connector?

No. The 16/32-point modules use removable terminal blocks; IC655MDL503 uses high-density front connectors.

What must be retained when replacing IC655MDL501 / IC655MDL502 / IC655MDL503?

Retain the exact model, starting reference, group commons, polarity and the matching terminal block or cable harness.
