Allen Bradley Modules 1746-OV8 AB 1746-OV8 SLC 500 Digital I/O Modules Installation

Product Description:

The AB 1746-OV8 is DC output module which is part of the SLC 500 output module series. Its backplane current is 135mA at 5V and it is 0A at 24V. When supplied with an external power supply, the 1746-OV8 draws a current of 0.8A at 24V and of 0A at 5V. It is a current sinking module with 8 I/O points and 8 points per common. The 1746-OV8 operates in a voltage category of 24V DC within a 10-50V DC voltage range. At 1A, the 1746-OV8’s maximum on-state voltage drop is 1.2V. In addition, it has an off-state leakage current (output) of 1mA. Its on-signal delay is 0.1ms maximum

The 1746-OV8 output module’s continuous current is 1A per point at a temperature of 30 degrees Celsius and the current is 0.5A at 60 degrees Celsius. Note that a resistor can be mounted in parallel to the load to scale down the effects of a leakage current. The 1746-OV8’s heat dissipation rating is 0.775W per point, with a minimum of 0.675W and a maximum of 6.9W. A Hand-Held terminal orWindows programming software (compatible) must be used when reconfiguring the module. The 1746-OV8 has an operating temperature of between 0 and 60 degrees Celsius.
