Allen-Bradley 1794-OE12 Flex IO Analog Output Module 12-Ch

Product Overview: 1794-OE12 High-Density Analog Output Module

The 1794-OE12 from Allen-Bradley is a high-density Flex IO analog output module. Specifically, it delivers twelve single-ended, non-isolated channels. Furthermore, it supports 0-20 mA, 4-20 mA, and ±10V DC signal ranges. This module converts digital data with 16-bit resolution (2’s complement format). Consequently, it provides dependable signal conversion for precise industrial automation.
