It has an operating voltage ranging between 5-125V DC and 5-265V AC. Additionally, the 1746-OX8 operates at a backplane current of 85mA at 5V DC and 90mA at 24V AC. The heat dissipation for the module is 0.825W per point. Minimum dissipation measures at 2.590W with a total of 8.60W.

The 1746-OX8 has a maximum resistive load single delay of 10.0ms when ON and 10.0ms when OFF. Backplane current consumption for the module is 0.085A at 5V DC and 0.090A at 24V DC. In addition, the module has a 0mA maximum off-state leakage and a minimum load current of 10mA at 5V DC. The continuous current per module must be limited to prevent the module power from exceeding 1440VA. The 1746-OX8 has a relay contact rating of 30A at 120V AC maximum with a break of 3.0A at 240V AC, and a relay contact rating of 15A with a break of 1.5A. In addition, the 1746-OX8 has a relay contact rating of 0.22A and 1.2A at 125V DC and 24V DC respectively.

The 1746-OX8 has a Class 1, Division 2 endorsement to be used in a hazardous environment. The operating temperature for the 1746-OX8 ranges between 0-60º C (32-140º F) and the non-operating temperature ranges between -40-85º C (-40-185º F) at 5-95% non-condensing operating humidity. The module adheres to the CS-232 NEMA standard for noise standards. The 1746-OX8 has an operating vibration displacement of 0.015” peak at a speed of 5-57 Hz with an acceleration of 2.5g at 57-2000Hz. It has an operating shock of 10g and a 1500V isolation.
