The 1746-OBP16 is a high-current digital output module for the SLC 500 system. This unit provides sixteen discrete sourcing outputs for demanding industrial applications. It delivers a robust 20.4 to 26.4 Volts DC for reliable actuator control. Engineers trust this module for its integrated electronic fuse protection. This design safeguards each channel from short-circuit and overload conditions. The 1746-OBP16 occupies a single slot in any SLC 500 chassis. It works perfectly with both fixed and modular hardware configurations.
Theme A: Product Procurement & Buyer Guide
Procurement managers need a module that offers high reliability and easy maintenance. The 1746-OBP16 delivers exactly that with its per-channel fuse protection. This feature minimizes system downtime by isolating faults to a single output. Other channels continue operating normally when a fault occurs. This module uses a Littelfuse 322010 or 332010, 10A fuse. The replacement fuse kit is the Allen-Bradley 1746-F8, which contains five fuses. Replacing a blown fuse requires removing the module from the chassis. This process is straightforward and does not require special tools.
Application engineers will appreciate the high current capability of this module. Each output can handle up to 1.5 Amps, with a total module current of 6.4 Amps. The module draws only 250 milliamps from the 5 Volt backplane. This low backplane current leaves power for other system modules. The output voltage range of 20.4 to 26.4 VDC suits standard 24V industrial loads. This module is a perfect choice for driving solenoids, contactors, and indicator lights. Its sourcing configuration makes it compatible with common PLC output wiring schemes.
The step response of this module is critical for time-sensitive applications. It has a 60 millisecond turn-on time and a 2.5 millisecond turn-off time. This fast response ensures precise control of your output devices. The module also includes an E-FUSE LED on the front panel. This LED illuminates to indicate a channel short-circuit or overload condition. This visual feedback helps technicians quickly identify and correct faults. The module automatically resets after power is cycled and the fault is cleared. You must consider this automatic recovery in your system's fail-safe design.
