The 1746-OB6EI is a DC output module by Allen-Bradley. It is part of the SLC 500 series of DC controllers. The 1746-OB6EI has 6 outputs that are individually separated and electronically protected. The module automatically rests during an overload. To prevent the auto reset feature of the 1746-OB6EI from triggering, a mechanical external fuse can be used. The 1746-OB6EI has a wattage rating of 0.44W per point, 0.23W minimum and 2.9W maximum.
The 1746-OB6EI operates at 24V DC nominal within a voltage range of 10-30V DC. The 1746-OB6EI draws a backplane current of 0.046A at 5V and of 0A at 24V. At a maximum resistive load, the 1746-OB6EI has a signal delay of 1ms and 2ms in the ON and OFF states, respectively. In addition, it has a 1mA off-state leakage and a minimum load current of 1mA. When operating at a temperature between 0 and 60 degrees Celsius, the 1746-OB6EI has a 2A continuous current per point. Its maximum on-state voltage drop is 1V at 2A.
The 1746-OB6EI has a surge current per point of 4A for 10ms and a 24A surge current per module for 10ms. The surge current repeatability occurs once every 1 second at 30 degrees Celsius and once every 2 seconds at 60 degrees Celsius. Surge suppressors are used with inductive loads on the 1746-OB6EI for a fast-off delay. The 1746-OB6EI’s electrical protection caters for short circuits and does not protect the module against reverse polarity or AC power wiring.
