PLC Expansion Modules | Allen-Bradley 1745-E105
The Allen-Bradley 1745-E105 is a dedicated relay output expansion module designed for the SLC 100 programmable logic controller system. Providing 12 electromechanical relay outputs with zero input circuits, it extends discrete control capacity for field actuators, contactors, and indicators. The unit interconnects with the primary processor using a 1745-C2 10-pin expansion cable, maximum enabling I/O expansion up to 112 circuits across the control system.
Power Architecture and Load Isolation
The module incorporates selectable AC line voltage options of 100/200 VAC or 120/240 VAC at 50/60 Hz, drawing a maximum power of 28 VA. Its 12 output channels feature high-capacity relay contacts capable of switching load ranges from 10 to 250 VAC or 10 to 125 VDC.
Built to NEMA standards, the module ensures robust contact isolation between field load circuits and controller logic. The compact chassis design facilitates straightforward mounting alongside base SLC 100 processors within standard control enclosures.
