Features:
- Relay output role: switches documented discrete field circuits.
- Contact-map control: retains the installed relay and common assignments.
- Field-load boundary: accounts for voltage, inrush and safe state.
The module provides relay contacts rather than a self-powered field-output source, so the external circuit remains part of its identity.
Contact assignments, commons, load behavior and suppression must be reviewed together before a spare is accepted.
A controlled test proves released and energized states plus the intended field feedback before automatic control is restored.
