The Allen-Bradley 1746-OBP16 is a digital output module that belongs to the SLC 500 series of output controllers. It has 16 output points and it is suitable for high-current environments. The 1746-OBP16 operates with a voltage of between 20.4 and 26.4V DC. It draws a 250mA backplane current at 5V and of 0A at 24V. It has a blown fuse indicator where the words “processor error” and a “blown fuse” LED indicator will glow when a fuse blows.  The 1746-OBP16’s heat dissipation rating is 0.31W per point, with a minimum dissipation of 1.25W and a total dissipation of 6.26W.


The 1746-OBP16 comes with 16 points per common. On a maximum resistive load, the 1746-OBP16 has a signal delay of 0.1ms in the on-state and 1ms in the off-state. It also has a 1mA minimum load current and a 1mA off-state current leakage. The continuous current per point for the 1746-OBP16 is 1.5A at 86 degrees Fahrenheit and 1A at 140 degrees Fahrenheit. It has continuous current per module of 6.4A at 32-140 degrees Fahrenheit and a surge current per point of 4A for 10ms. The 1746-OBP16 has a maximum on-state voltage drop of 1V at 1A and it has a surge current of 32A per module for 10ms.


The 1746-OBP16 has a removable terminal block. Since it is not electronically protected, an external fuse can be incorporated to cater to short circuit protection although it has a fused common. The 1746-OBP16 is Class 1, Division 2 CSA certified for use in hazardous locations.
