Features:
- 1500 V DC isolation: separates the DH-485 trunk from attached equipment
- Six-position network block: provides removable daisy-chain wiring
- Series-aware labeling: requires terminal-number matching during service
1747-AIC protects and connects one node on an SLC 500 DH-485 network.
Its value lies in the isolation boundary and repeatable removable-terminal wiring rather than protocol conversion.
Series-dependent labeling makes the physical terminal map the safest reference during replacement.
Apter Power can review 1747-AIC Series, terminal map, cable selection, official records, condition, and quotation needs.

Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
- Terminal numbers: preserve the six-position connector map across Series changes
- Daisy-chain path: keep the trunk continuous through each link coupler
- End-node treatment: apply the documented termination only at the network boundaries
- Protected sides: distinguish the DH-485 cable from processor and peripheral connections
- Shield ground: bond the trunk at one approved point to avoid circulating current
- Cable separation: maintain the official clearance from power wiring and noise sources
- Processor connection: use the documented 1747-C11 path for an SLC node
- Peripheral connection: choose 1747-C10 or 1747-C20 for the approved distance
- External power: provide 24 V DC when the connected device or cable does not supply the coupler
- SLC processor node: connect a controller to an installed DH-485 trunk
- Programming access: isolate a supported interface or terminal from the network cable
- Longer peripheral link: extend an approved DH-485 connection beyond a direct short cable
