Allen-Bradley Technical Characteristics
- Backplane Bus Communication Velocity: The 1745-C3 A utilizes twisted-pair signal routing across a 20-pin to 10-pin interface layout, minimizing crosstalk and signal propagation delay between high-speed input hardware and expansion backplane logic.
- I/O Density Scaling: Enables modular system expansion by connecting high-speed input functions directly to downstream expansion units without signal attenuation or deterministic execution delays.
Frequently Asked Questions
Q: Can the 1745-C3 A cable be hot-swapped while the SLC 150 processor unit is powered? A: No. The 1745-C3 A carries critical backplane signal paths between modules. Disconnecting or connecting this assembly under power can cause CPU fault states, logic disruption, or electrical stress on internal components.
Q: What is the maximum voltage rating for the 1745-C3 A interconnect cable conductors? A: The conductors within the 1745-C3 A assembly are rated for a maximum line voltage of 70 V max.
Q: Can the 1745-C3 A cable be modified or extended for longer cable runs? A: No. Extending or splicing the 1745-C3 A alters line impedance and propagation delay, which degrades deterministic communication velocity and high-speed pulse processing across the backplane bus.
Field Installation Guidelines
- Isolate primary system power from the SLC 150 processor and all associated expansion chassis before installing or removing the 1745-C3 A cable.
- Verify pin orientation on both the 20-pin header and 10-pin connector prior to insertion to prevent pin deformation or misaligned contact seating.
- Ensure the cable route maintains a minimum bend radius of 1.0 in (25.4 mm) to avoid strain on termination points.
- Separate the interconnect cable from high-voltage AC conductors, motor output wiring, and heavy inductive loads to prevent noise coupling.
