Allen-Bradley 1794-OE4 SER B Output Module

The Allen-Bradley 1794-OE4 Series B is part of the FLEX™ I/O family, known for its flexibility and efficiency in distributed control systems. This module provides four single-ended analog output channels, each configurable for current (0-20 mA, 4-20 mA) or voltage (0-10 V DC, ±10 V DC) signals, making it suitable for various control needs. It features a 12-bit plus sign resolution for precise signal conversion, essential for high-accuracy applications. The module uses pulse-width modulation (PWM) for signal conversion and supports a 16-bit 2's complement left-justified data format. Compatible with FLEX I/O adapters such as Ethernet, ControlNet, and Profibus, it integrates seamlessly into diverse network architectures. Its compact design and removal and insertion under power (RIUP) capability enable easy implementation and maintenance, reducing downtime.
