## Overview

The ASI451124 4-20mA Signal Splitter is a high-accuracy, DIN rail-mounted analog isolator that converts one input signal into two fully isolated outputs. Powered by 24V DC and featuring 3-way isolation, it eliminates interference and ground loops, ensuring stable signal transmission for industrial automation, SCADA, and process control systems. Easy to install with screw clamp terminals and zero/span calibration, it’s trusted for reliable multi-point signal distribution across demanding environments.

## Description

The ASI451124 4-20mA Signal Splitter ensures precise and interference-free signal duplication, allowing one input signal to be distributed into two fully isolated outputs. Designed for industrial process control, automation systems, and SCADA applications, this DIN rail-mounted signal conditioner operates on 24V DC power, making it ideal for multi-point signal distribution in PLCs, remote I/O, and monitoring applications. With high accuracy and fast response time, the ASI451124 prevents ground loops, electrical noise, and signal degradation, ensuring stable and efficient control system performance. Applications : 🔹 Process Control & Industrial Automation – Stable multi-output signal transmission for SCADA, PLCs, and automation networks. 🔹 Factory & Machine Automation – Ensures reliable data distribution for monitoring and control. 🔹 Water & Wastewater Treatment Facilities – Provides signal duplication for monitoring multiple sensors and actuators. 🔹 Oil & Gas, Power Generation & Chemical Processing – Maintains signal integrity in critical industrial environments. 🔹 Instrumentation & Sensor Applications – Enhances signal reliability for flow, temperature, and pressure monitoring.

Review: Life saver - Reliable and easy to apply. Solved a weird situation for me where a pressure regulator was designed to use an isolated loop powered sensor for it's own internal feedback loop but customer wanted to monitor the value at their PLC. Mixing the two circuits was not an option due to the way the PLC's analog input stage was designed (one side was grounded).

## Questions & Answers

**Q: Can this splitter except an active input and produce a passive output? if so will the power still need to be connected on the output side?**
A: I know the input can be active or passive. When I used one of these the outputs were active. I wired it like data sheet. I tied the output + to my plc analog input and the - to my DC common in my control panel. The other output went straight to a panel meter. I don’t know if it’s possible to wire outputs passive. You might give ASI a call. Sorry I couldn’t be more help.

### ⭐⭐⭐⭐⭐ Separate power supply
*by C***7 on December 12, 2018*

It needs a separate power supply from the sensor you are splitting the signal of, but otherwise worked great.
