Features:
- Switches eight 24 VDC sink-output loads at up to 2 A per point.
- Divides the outputs into four pairs protected by individual 5 A group fuses.
- Provides one LED indicator for each controlled output channel.
The four two-point groups keep load protection localized instead of placing all eight channels behind one fuse.
Fast 100 microsecond ON and OFF delays support responsive discrete load control.
The rack power budget must include both the module 5 VDC demand and the 12 VDC current used by active points.
The General Electric IC630MDL351 24 VDC Sink Output Module may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

Working with the four output pairs
- Channel count: Eight sink outputs are arranged as four groups of two.
- Shared protection: Both points in each pair depend on the same 5 A group fuse.
- Fault pattern: Two inactive loads in one pair should prompt a group-fuse and supply check.
- Point indication: Individual LEDs help compare the command state with field-load behavior.
Checking a pair that has lost field power
- Fuse rating: Each two-output group is protected by a 5 A fuse.
- Load total: Confirm the combined current of both channels stays within group protection limits.
- Fault isolation: Disconnect a shorted load before replacing the affected fuse.
- Restart check: Verify both paired outputs after field power is restored.
Matching the output to a 24 VDC load
- Field supply: Maintain 24 VDC within plus or minus 10 percent and below 3 percent RMS ripple.
- Point current: Each output can switch up to 2 A at 24 VDC within derating limits.
- Voltage drop: Allow for as much as 1.5 V across a conducting output.
- Leakage: OFF-state current is specified below 200 nA.
Accounting for backplane and point demand
- Logic supply: Reserve 20 mA from the internal 5 VDC source for the module.
- Point supply: Add 12.5 mA from internal 12 VDC for every active output.
- Response: Both ON and OFF delays are specified at 100 microseconds.
- Thermal review: Check simultaneous load current against the published temperature derating curve.
