Allen Bradley 1746-OX8 SLC I/O Digital Modules

Allen-Bradley has an output current of 3 A at 120 Volt AC and an output current of 1.2 A at 24 Volt DC. The operating voltage of this module ranges from 5-125V AC and 5 to 265 Volts DC. The backplane current consumption at 5 Volts DC is 0.085 A and 0.090 A at 24 Volt DC. It also has a maximum resistive load signal delay of 10 milliseconds for both OFF and ON. This module's minimum load current is 10 mA at 5 Volts DC and its maximum off-state leakage is 0 mA. Note that the continuous current per module should be limited to 1440 VA. This module has a NEMA standard ICS 2 to 230 noise immunity and electro-optical isolation of 1500 Volts between the I/O terminals and control logic. The operating temperature range of this module, particularly for the air surrounding the system, is from 0 to 60 degrees Celsius and the storage temperature ranges from -40 to 85 degrees Celsius. Its operating vibration has a displacement of 0.015 inches peak at 5 to 57 Hertz and an acceleration of 2.5 g at 57-2000 Hertz. The operating shock of this module is 10 g. The 1746-OX8 module has a heat dissipation of 0.825 watts per point, a minimum dissipation of 2.590 Watts, and a total dissipation of 8.60 Watts.
