1746-OV8 Allen Bradley digital I/O module for the SLC 500 system

The Allen-Bradley 1746-OV8 is a digital I/O module for the SLC 500 system. It is a current sinking 24V DC output module and it has applications in general use. The 1746-OV8 module has an operating voltage of 10-50V DC (sink) and 8 outputs with 8 point per common. It has a backplane current consumption of 135mA at 5V DC and 0mA at 24V DC. It has a maximum signal delay of 0.1ms in On-state and 1ms in Off-state. The 1746-OV8 has a continuous current per output and per module of 1A and 8A at 30°C and 0.5A and 4A at 60°C respectively. It has a maximum Off-state leakage of 1mA and a maximum thermal dissipation of 6.9W. It has a maximum On-state voltage drop of 1.2V at 1A and 3A for 10ms maximum surge current per point. The 1746-OV8 is also equipped with color-coded removable terminal blocks. For wiring, a pre-wired cable and a 1492 interface module can be used. The 1746-OV8 module has self-lifting pressure plates at the terminals that can accept up to two 14 AWG (2 mm2) wires. To display the I/O point status, it has LED indicators on the front panel. The 1746-OV8 is intended for use in a clean and dry industrial environment with a 0 – 60 °C operating temperature and a 30g operating shock.

The Allen-Bradley 1746-OV8 is a Discrete Output module. This module is part of the SLC 500 product family. It features eight (8) sinking output channels that operate at voltage range of 10-50 Volts DC.
