Allen Bradley1746-IO12 SLC 500 Combination I/O Module New

Details

The Allen-Bradley 1746-IO12 is a SLC 500 Digital I/O Combination Module. This Digital I/O Combination Module has Six (6) Input channels with Operating Voltage range of 85-132 Volts AC and Six (6) relay output channels. This module occupies single slot of the SLC 500 chassis.

The Allen Bradley 1746-IO12 is a 120 Volt AC SLC 500 Input/Output Digital Combination Module. It has six 100 to 120 Volt AC outputs and six 120 Volt AC inputs, with six points per common. Its input operates at a voltage range of 85 to 132 Volts AC, while output operates at a voltage of 5 to 125 Volts DC or 5 to 265 Volts AC. At 5 Volts, the backplane current is 90 mA; at 24 Volts, it is 70 mA. It has 0.27 Watts per input point and a 0.133 Watts per output point. Its maximum heat dissipation is 2.13 Watts, its minimum being 4.6 Watts, and the signal delay on the input and output points are 35 milliseconds in ON state and 45 milliseconds in OFF state.

The 1746-IO12 comes equipped with removable, color-coded terminal blocks. It has a normally open contact type output with a 1.5A nominal current at 12 Volts AC. The LED indicators on this combination module facilitate simpler troubleshooting by displaying the status of the I/O points; however, when the rack is not under processor control in the first few seconds of a power-up, the output LED lights will be on.
