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.

The Allen-Bradley SLC 500 1746-OBP16 module is an output module with fuse protection. The fuse on the module provides short circuit protection for wiring with 16 AWG or higher-gauge wires to external loads. If a short circuit occurs on an output channel and it damages the channel transistor, then either the module will need replacement or the load will need to be moved to a spare channel on the module. The fuse on the 1746-OBP16 module does not provide overload protection. User-supplied fuses should be used to provided overload protection on the output channels. For overload protection, Allen-Bradley recommends the use of external fuses which are matched to the load. If a fuse blows on the module, then the LED indicator provided for the indication of a blown fuse will light up as long as the module is connected to the backplane power.

All of the outputs on the 1746-OBP16 module are deactivated if the fuse blows. The processor continues with the module outputs deactivated if JP1 is set to “Processor Continues” and all processor operations cease with the outputs deactivated if JP1 is set to “Processor Faults”. There are 16 output channels on the 1746-OBP16 module which support 20.4 to 26.4 Volts DC operating range. At 5 Volts DC, the module draws 0.25 Amps from the backplane. The continuous current per point is 1.5 Amps at 86 degrees Fahrenheit and 1 Amp at 140 degrees Fahrenheit. The on-state maximum voltage drop is 1 Volt at 1 Amp. The rated surge current per output point is 4 Amps for 10 milliseconds and the rated surge current per module is 32 Amps for 10 milliseconds.
The Allen-Bradley 1746-OBP16 module is an output module. It supports short-circuit protection for the output channels through an integrated fuse.
