Allen Bradley 1747-C13 SLC Cable

Configured for DH485 and RS-232C physical interconnection within SLC 500 communication chains, the Allen Bradley 1747-C13 (1747-C13 SLC cable) provides direct electrical linking between interface modules and link couplers via DH485 network ports and J2 peripheral connectors in SLC controller architectures.

Hardware Specifications

DH485 signal routing and RS-232C interface coupling behavior

The 1747-C13 implements passive conductor routing for DH485 network signaling and RS-232C level interface adaptation through dedicated pin mapping across interface modules and link coupler ports. Signal transmission is constrained to defined impedance paths with no active conditioning, maintaining deterministic serial communication timing between SLC controllers and peripheral interface nodes.

Frequently Asked Questions (FAQ)

Q: Does the 1747-C13 contain any active signal conversion electronics?
A: No active circuitry is present. The cable functions as a passive physical layer interconnect for DH485 and RS-232C mapped signals.

Q: Can the cable be used interchangeably with Ethernet cabling?
A: No. Electrical pinout and signaling standards are specific to DH485 and RS-232C interfaces and are not compatible with Ethernet PHY layers.

Q: Is the cable suitable for hot-plug operation during controller runtime?
A: Hot-plug insertion is not supported. Connection should be performed under controlled communication idle state to avoid frame corruption.

Field Installation Guidelines

• Verify controller and interface module are in communication halt state before cable connection.

• Ensure DH485 and RS-232C ports are correctly identified prior to mating.

• Maintain minimum bend radius consistent with industrial serial cabling practice.

• Route cable away from high-voltage conductors to reduce electromagnetic coupling.

• Confirm continuity of shielding and reference ground at a single-point earth termination.
