1745-E104 | Allen-Bradley PLC Expansion Units
The 1745-E104 is an expansion chassis unit designed for Allen-Bradley SLC 100 programmable logic controller (PLC) systems. Functioning as an add-on expansion unit for the main 1745 SLC 100 processor unit, it expands system input and output capacity across standard 10 to 250 VAC operating voltage ranges at 50/60 Hz while consuming 0.22 A of operating current.
System Integration and Functional Operation
The 1745-E104 connects directly to the host SLC 100 base controller to increase the discrete I/O density of the control setup. It allows maintenance personnel and automation technicians to incorporate additional field switches, contactors, relays, and indicators into existing legacy SLC 100 architectures without altering the primary controller footprint.
High-Voltage Operational Warning
Isolate the primary power line feeding the SLC 100 base controller and expansion unit before installing, servicing, or modifying terminal wiring. Voltages up to 250 VAC are present at the field connection terminals.
