The 1745-E156 SLC 150 expansion I/O module by Allen-Bradley is an electronic device used with an SLC 150 processor module to increase the number of I/O modules to 112 points. It has twenty optically-isolated 10 to 30 Volts DC current sourcing inputs, 12 hard contacts, and transistor base outputs. It has an input ON-state voltage range of 10 to 30 Volts DC, and a maximum OFF state voltage of 4 Volts at a 1mA leakage current. It has a nominal input current of 4mA at 12 Volts DC and 8mA at 24 Volts DC and has an input filter delay time (ON to OFF) ranging between 4 and 8 milliseconds. It is built with an electrical-optical isolation of 1500 Volts DC tested between the input voltage and control logic.
The 1745-E156 has a transistor-based output voltage range of 10 to 50 Volts DC, with a continuous output per circuit current of 1 Amp at 30 degrees Celsius, which begins to de-rate uniformly at 60 degrees Celsius to 0.5 Amps. Its transistor output has an inrush current of 3 Amps for 20 milliseconds repeatable every 1 second at 30 degrees Celsius and has a maximum current load of 1.0mA and a leakage of 0.1mA. The 1745-E156 has 12 hard contact relay outputs with a contactor rating of 10 to 125 Volts DC and a current of 2.5A and 28VA apparent power. It contactor output has a resistance rating of 20 milliOhms and uses a Bussman 3 Amps, 250 Volts AC slow-blow fuse. The 1745-E156 has an operational temperature range of 0 to 60 degrees Celsius at 5 to 95% non-condensing relative humidity.
