Performance and Protection

The 1769-OB16P module ensures excellent performance with fast output transition times of 1 ms for ON and 2 ms for OFF. It provides a 24VDC output and can handle 0.5 A per point at 30°C (86°F) or 1.0 A per point at 60°C (140°F). Additionally, the module supports 2.0 A surge current for 10 ms, repeating every second. This feature protects the module in environments with high electrical transients.

To further enhance safety, the module integrates IEC Class 2 reinforced insulation, offering protection against voltages up to 75VDC. It also includes a 1769-RTB18 Removable Terminal Block (RTB), simplifying maintenance and module replacement.

Installation and Compatibility

Install the 1769-OB16P module as a local I/O or expansion I/O module for both CompactLogix and MicroLogix 1500 controllers. It offers flexible mounting options for both DIN rail and panel installations. To ensure proper functionality, keep the module within the power supply distance rating of 8 modules from the power supply.

The module operates within a voltage range of 20.4VDC to 26.4VDC and draws 160 mA at 5.1V DC from the backplane. Use this module for reliable and efficient control in your industrial systems, providing fast response times and high current ratings.
