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.
