More Information

Overview Manuals Input Range Signal Mapping Rack Integration Power Budget

Features:

  • Provides sixteen discrete input circuits for a Series Three controller rack.
  • Accepts field signals designed around a nominal 24 VDC supply.
  • Can participate in a Series Five I/O system through the required Series Three I/O interface.
Each energized field circuit is represented as an individual input state, allowing the control program to evaluate switches, contacts and other discrete devices without combining their status.

The allowable voltage window accommodates normal variation around a 24 VDC field supply while retaining a defined electrical boundary for signal checks.

Its input-only construction also matters in mixed-generation layouts because the documented Series Five remote-I/O restriction applies to Series Three modules that combine inputs and outputs, rather than this dedicated input module.

Apter Power can quote and source the General Electric IC630MDL301 24 VDC Sink Input Module for established Series Three and compatible Series Five I/O requirements.

Electrical boundaries for the sixteen inputs

  • Nominal supply: The module is intended for discrete circuits centered on 24 VDC operation.
  • Accepted window: Field voltage is specified from 21.5 to 26.5 VDC.
  • Current limit: The listed maximum input current is 15 mA.
  • Polarity role: As a sink input, each channel depends on the matching source-side field device and common return.

From field contact to controller reference

  • Point count: Sixteen field circuits are presented as separate discrete input points.
  • State handling: Each point reports an ON or OFF condition for use by the control program.
  • Reference continuity: Existing point assignments should be recorded before hardware is removed so program addresses remain aligned with field wiring.
  • Channel comparison: A suspect point can be checked against a working input while the same field condition is applied.

Using Series Three I/O with a Series Five CPU

  • Native placement: IC630MDL301 is installed as a Series Three I/O module in the appropriate Series Three rack.
  • Interface requirement: A Series Three I/O Interface module connects that rack to a Series Five rack and CPU.
  • Remote-I/O boundary: The stated exclusion concerns Series Three modules that combine inputs and outputs; IC630MDL301 is input-only.
  • System record: Rack position and controller reference allocation should stay consistent when the module is exchanged.

Internal logic load and field-power separation

  • Load-unit value: IC630MDL301 is assigned eleven load units on the +5 V supply.
  • Current equivalent: Eleven load units correspond to 110 mA of internal +5 V demand.
  • Rack calculation: The module load must be included with the other installed units when checking available backplane power.
  • Field-side distinction: The 24 VDC input circuit supply is separate from the module’s internal +5 V rack load.
Description
Within a Series Three rack, General Electric IC630MDL301 is a 16-point 24 VDC sink input module that converts individual field-contact states into controller references.

Each IC630MDL301 channel accepts the state of a compatible low-voltage device, keeping sixteen independent on/off conditions together in one input position without mixing output circuitry into the module.

The 21.5 to 26.5 VDC operating window and 15 mA maximum input current define how IC630MDL301 recognizes an energized circuit. Field voltage outside that window must be corrected at the source or wiring rather than treated as a valid PLC input.

A Series Five CPU can exchange these Series Three input states through the required Series Three I/O Interface module. In that arrangement, IC630MDL301 remains an input-only device while the interface provides the connection between controller generations.

Technical notes
Reserve eleven +5 V load units for IC630MDL301, then verify 21.5–26.5 VDC field power, common-return continuity, channel wiring and assigned input references before operation.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
Why are all IC630MDL301 input points inactive after installation?
For IC630MDL301, confirm 21.5–26.5 VDC field power, sink polarity, the common return and sufficient rack +5 V capacity. If every channel remains inactive, check shared power and module seating before tracing individual field circuits.
What should be checked when only one IC630MDL301 input remains OFF?
For IC630MDL301, measure the affected terminal while its field device is actuated and compare its wiring, LED indication and controller reference with a working point. One failed device or conductor can leave a single channel OFF while the rest operate normally.
Can IC630MDL301 be used with a Series Five controller?
IC630MDL301 can operate in a Series Five system only through the required Series Three I/O Interface module. Confirm the interface connection, rack assignment and +5 V power budget before relying on the input states in the Series Five program.
What must be documented before moving IC630MDL301 to another rack position?
Before moving IC630MDL301, record its present slot and all sixteen input references because the Series Three slot establishes the module address. After relocation, verify that the program and field documentation follow the new reference range.
What should be recorded before replacing IC630MDL301?
Before replacing IC630MDL301, capture the terminal schedule, input-reference assignment, 24 VDC polarity, common return and current LED pattern. Restore one circuit group at a time and compare the resulting controller states with that record.
How can intermittent IC630MDL301 input changes be investigated?
For intermittent IC630MDL301 behavior, monitor voltage during actual switching and inspect the common return, contact condition, conductor integrity, grounding and nearby noise sources. Replace IC630MDL301 only after field-side instability and reference-mapping errors have been excluded.
