Features:
- Supplies thirty-two commoned 24 VDC output signals.
- Uses self-protecting switches rated for two amperes per point.
- Supports de-energize-to-trip behavior during a stuck-on fault.
The selected module is the 3674 dual-output version rather than the similar 3664 operating-behavior variant.
It sources DC power to field devices and monitors the commanded state through ongoing diagnostics.
Engineering review must cover the total current, surge profile, common field supply and fault-response expectations.
Availability is subject to Apter Power inventory and sourcing confirmation.

- Drives groups of 24 VDC shutdown solenoids in de-energize-to-trip schemes.
- Controls commoned DC actuators that require point diagnostics without external output fuses.
- Provides a like-for-like spare for installed 3674 safety-output positions.
- Point indicators show the commanded on or off state for all thirty-two outputs.
- Module status indicators report PASS, FAULT and ACTIVE conditions to maintenance personnel.
- A field alarm identifies load or switch behavior that does not follow the commanded result.
- The operational field-voltage window is 16 to 30 VDC with a 36 VDC maximum.
- Each point supports up to 2 A and the documented ten-millisecond surge limit.
- Typical on-state drop remains below 1.5 VDC in the stated load range.
- Output switches are self-protecting, so the standard termination does not require individual fuses.
- Minimum point isolation is specified at 1500 VDC.
- The stuck-on response commands the remaining outputs to their de-energized state.
