Apollo SA4700-102APO — Intelligent Input/Output Unit for XP95, Discovery and CoreProtocol addressable loops, with a built in short circuit isolator.
It supervises one or more normally open contacts wired on a single pair and switches one set of changeover relay contacts, so a panel can read a remote contact and drive plant from one address. A failsafe DIL switch drops the relay on loss of loop or protocol, meeting BS 7273-4 for door holders.
- Supply 17 to 35 V dc; protocol 5 to 13 V peak to peak
- Quiescent 500 µA, 3.5 mA maximum with LEDs on, 900 µA power up surge
- Relay output contacts rated 1 A at 30 V dc or ac
- Carries the 20C isolator and an Equivalent Detector Load of 1
- -40 °C to 70 °C, 0 to 95% RH non-condensing, IP52
- 60 × 150 × 90 mm, 244 g, EN 54-17 and EN 54-18
- Back box supplied for surface mounting
Do not confuse it with SA4700-104APO, the twin input/output module, or SA4700-103APO, the 250 V ac version; SA4700-100APO monitors a switch only. The legacy XP95 55000-847APO differs in Apollo isolator terms, carrying the older 20D isolator and an Equivalent Detector Load of 4 against 1 here.
