Allen-Bradley 1794-OE12 Analog Output Module 12 Ch

Product Overview

The 1794-OE12 is a high-density analog output module. It is part of the Allen-Bradley Flex IO family. This module has 12 single-ended channels. Each channel can output voltage or current signals. Supported signals include 0-20 mA and 4-20 mA. It also supports +/-10 VDC. The module uses a 16-bit digital-to-analog converter. This ensures precise control. 1794-OE12 is ideal for many automation tasks.

Application Scenarios

Use this module in process control systems. It works well for valve positioning. It is good for analog signal generation. Use it in automotive assembly lines. It fits in food and beverage processing. The module handles harsh industrial environments. Its wide operating temperature range from -20 to 60 degrees Celsius helps. It also withstands shock up to 30 g. Vibration resistance of 5 g at 10-500 Hz is robust.
