PRODUCT INFORMATION
Product Overview
The Allen-Bradley 1794-OB16 is a 16-point digital output module in the FLEX I/O platform. It delivers current sourcing DC outputs designed for industrial automation tasks. The module operates at a nominal voltage of 24V DC. Operating output voltage spans from a minimum of 10V DC up to 31.2V DC.
The unit provides fast switching times to support time-critical operations. Its off-to-on signal delay is 0.5 milliseconds. The on-to-off delay is rated at 1 millisecond. Sixteen yellow status indicators give instant channel feedback during live operation. The module uses an open enclosure design and keyswitch position 2 for base installation.
