1756-OB16E Functional Description  

The 1756-OB16E is a DC discrete output module designed for use with Allen-Bradley’s ControlLogix programmable automation controllers (PLCs). It provides a robust solution for controlling 24VDC devices, such as relay coils, solenoid actuators, pilot lamps, and sirens. This 1756-OB16E DC discrete output module  features sixteen (16) output channels, grouped into two sets of eight channels, each with built-in electronic fuses for protection. The module operates within a voltage range of 10-31.2 VDC, with a nominal output of 24VDC.

Ideal for applications requiring high reliability, the 1756-OB16E DC discrete output module is compatible with 1756 ControlLogix controllers, fitting into various racks like the 1756-A4, 1756-A17, 1756-A10, and more. It can function as both local and distributed I/O, offering versatility in industrial settings. The module supports an output current of 1A per channel at 60°C (140°F), with a maximum current of 8A per module. It also has a surge current rating of 2A per point for 10 ms, repeatable every 2 seconds.

With electronic fusing on each output group, the 1756-OB16E DC discrete output module  offers solid protection and efficiency. The module has a minimum load current of 3 mA per channel and operates with a backplane current draw of 250 mA at 5VDC and 2 mA at 24VDC. The power dissipation reaches 4.1 W at 60°C, making it suitable for demanding environments. Moreover, it provides quick response times with 70 µs nominal (1 ms max) for ON/OFF delays, ensuring precise operation in time-critical applications.

This 1756-OB16E DC discrete output module  is also designed to withstand routine testing at 1350V AC for 2 seconds, with a continuous isolation voltage of 250V. It operates within a temperature range of 0-60°C, with non-operating conditions from -40°C to 85°C. The 1756-OB16E is a reliable, efficient, and flexible solution for controlling various electrical loads in automation systems.
