The PLC 1746-OX8 module is an SLC 500 channel to channel isolated relay output module. The operating temperature range for the module is 32 to 140 degrees Fahrenheit. The non-operating temperature range is -40 to 185 degrees Fahrenheit. The recommended non-condensing operating humidity range is 5 to 95%. The rated noise immunity meets the NEMA ICS 2-230 standard. The operating vibration rating is 0.015 inches of displacement at 5 to 57 Hertz. The operating shock rating for the 1746-OX8 module is 10 g. the module is certified by the UL, CSA, and CE standards. The rated heat dissipation per energized point for the module is 0.825 Watts. The minimum heat dissipation when no field power is applied is 2.59 points. The total heat dissipation for the module when all the outputs are energized is 8.6 Watts.
The 1746-OX8 module has 8 individually isolated outputs. At 24 Volts DC backplane voltage, the module consumes 0.09 Amps of current and at 5 Volts DC backplane voltage, the module consumes 0.085 Amps. In the on-state the signal delay with a maximum resistive load is 10 milliseconds. In the off-state, the signal delay for the maximum resistive load is 10 milliseconds. The operating voltage range with a 5 Volts DC supply is 5 to 125 Volts and with a 24 Volts DC supply, it is 5 to 265 Volts. The peak off-state leakage is 0 milliamps. The minimum level of recommended load current is 10 milliamps at 5 Volts DC. At 120/240 Volts AC, the continuous current per point is 2.5 Amps. At 125 Volts DC, the continuous current per point is 1 Amp and at 24 Volts DC, the continuous current per point is 2 Amps.
