The Allen-Bradley 1745-LP153 Processor Unit is a SLC 150-series PLC module that provides a total of 32 I/O points—20 sinking DC inputs and 12 relay outputs for 120 VAC loads. It operates from a 18–30 VDC supply and includes about 12K words of memory for user programs. The 12 relay outputs are hard-contact/triac relays capable of switching AC loads up to 250 VAC and DC loads up to 125 VDC. This processor unit is discontinued by the manufacturer.
