Moore Industries ECT/4-20MA/2X4-20MA/117AC-TX [DIN] Signal Isolator/Converter/Sp

Overview

The Moore Industries ECT/4-20MA/2X4-20MA/117AC-TX [DIN] is a 4-wire signal isolator, converter, and splitter engineered for reliable signal conditioning in industrial automation and process control applications. This unit accepts a single 4-20mA analog input and delivers two isolated 4-20mA outputs, each with a 600-ohm output impedance. The built-in 24V transmitter excitation option (-TX) enables direct connection to 2-wire transmitters without external power supplies. Mounted in a compact 45mm DIN-rail housing, this isolator provides galvanic isolation, signal conditioning, and simultaneous multi-output distribution in a single, space-efficient module.

Key Features

• Single 4-20mA input with dual isolated 4-20mA outputs
• Output A: passive (externally powered); Output B: active (sourced by ECT)
• 24V transmitter excitation for powering 2-wire field transmitters
• 117AC ±10% power supply (5W max), 50/60Hz
• 45mm wide DIN-rail housing (32mm G-type and 35mm Top Hat compatible)
• Fixed input/output ratio with no field reconfiguration required
