Allen-Bradley Technical Characteristics
- Backplane Bus Communication Velocity: Interfaces directly with the main SLC processor backplane ribbon connector, maintaining deterministic register update rates across expansion expansion logic frames.
- I/O Density Scaling: Integrates local input/output module positions into the primary controller memory map without requiring dedicated remote network adapters or signal repeaters.
Frequently Asked Questions
Q: Can the 1745-E102 expansion unit be installed or removed while system power is applied?
A: No. The 1745-E102 backplane interface must be connected or disconnected only when primary AC/DC power to the controller platform is fully isolated to prevent processor bus fault trips.
Q: What processor models support direct hardware connection to the 1745-E102?
A: The 1745-E102 expansion unit is engineered for direct interconnect compatibility with Allen-Bradley SLC 100 and SLC 150 base controller units.
Q: Does the 1745-E102 require a separate power supply connection for backplane bus operation?
A: Backplane logic power is drawn directly through the official interconnect cable connected to the main SLC processor or primary powered expansion unit.
Field Installation Guidelines
- Remove main incoming AC source power from the SLC 100/150 CPU base unit prior to mounting or wiring the 1745-E102 expansion chassis.
- Mount the chassis firmly to a grounded enclosure backplate using appropriate mounting screws to guarantee frame grounding integrity and thermal heat sinking.
- Route interconnect bus ribbon cables clear of heavy AC power conductors and VFD output leads to prevent noise interference on backplane logic traces.
- Maintain a minimum perimeter distance of 2.0 in (50.8 mm) around the unit for natural convection cooling inside the cabinet.
