1746-OV8 Allen Bradley

1746-OV8 Allen Bradley

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.

Features:

• Backplane current consumption of 135mA at 5V DC and 0mA at 24V DC.
• Maximum signal delay of 0.1ms in On-state and 1ms in Off-state.
• Continuous current per output and per module of 1A and 8A at 30°C and 0.5A and 4A at 60°C respectively.
• Maximum Off-state leakage of 1mA and a maximum thermal dissipation of 6.9W.
• Maximum On-state voltage drop of 1.2V at 1A and 3A for 10ms maximum surge current per point.
• Equipped with color-coded removable terminal blocks.
• For wiring, a pre-wired cable and a 1492 interface module can be used.
• 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.
