1734-OE2C 2-Channel Analog Output Module 4-20mA | Allen-Bradley

The Original New Allen-Bradley 1734-OE2C POINT I/O 2-Channel Analog Current Output Module is a compact analog output device designed for precise current loop control in distributed industrial automation systems. It provides two single-ended, non-isolated analog output channels, each configurable for 0-20 mA or 4-20 mA signals. Fully compatible with POINT I/O communication adapters and Rockwell Automation controllers, this module delivers precise control for valves, actuators, and other field devices requiring analog current signals.

Core Engineering Highlights:
2-channel 4-20mA / 0-20mA analog current outputs | 13-bit resolution (2.5 µA/count) | 24 µs step response (63% of FS) | 16 µs conversion rate | 0.1% absolute accuracy @ 25°C | 75 mA POINTBus current | 1.23 W power dissipation | 50V isolation | -20°C to +55°C operating temperature
