| Feature | Specification |
|---|---|
| Function | Relay output / digital output interface |
| Channels | 4–8 relay outputs (status, alarms, permissives) |
| Contact Rating | 2–5 A @ 24 VDC / 120 VAC (resistive load) |
| Isolation | Optical/electrical isolation between actuator logic and external circuits |
| Mounting | Internal PCB, rack-mounted inside actuator housing |
| Indicators | LED per channel (status/fault) |
| Operating Temp | −40 °C to +70 °C |
| Compliance | NEMA 4/6, IP68 (when installed in actuator enclosure) |
