1745-E153
Allen Bradley SLC-100 Expansion Module

The Allen Bradley 1745-E153 is a expansion unit can be used with either the SLC150 processor unit or SLC 100 processor unit to expand the number of I/O circuits to a maximum of 112.  The SLC 150 expansion unit has the same construction as the SLC 150 processor unit. Like the processor unit, it has 20 inputs and 12 outputs include triac, hand contact and transistor.
