MTL 5541 Potentiometer Isolator | 0-1kΩ Input, 4-20mA Output, IS, DIN Rail, ATEX/FM/CSA

MTL 5541 signal isolator specifications. Converts potentiometer/position signals (0-1kΩ) to 4-20mA, galvanic isolation, 24V DC, hazardous area certified, dual-channel.

Product Overview

The MTL 5541 is a dual-channel signal conditioner and isolator designed specifically for potentiometer and position transmitter signals. It accepts a resistance input (typically 0-1kΩ) from devices like valve positioners, level transmitters, or potentiometers in hazardous areas, converts it to an isolated 4-20mA output signal, and provides intrinsic safety (IS) isolation for the control system.

Technical Specifications

Key Features

• Potentiometer Interface:​ Specifically designed for 0-1kΩ potentiometer/position signals

• 3-Wire Connection:​ Supports 3-wire potentiometer wiring configuration

• Built-in Excitation:​ Provides 0.5mA excitation current for the potentiometer

• Dual Independent Channels:​ Two fully isolated potentiometer input channels

• High Accuracy:​ ±0.1% analog signal accuracy

• Intrinsic Safety:​ Certified for Zone 1/21 hazardous locations

• Complete Isolation:​ 500V isolation prevents ground loops and protects systems

• Active Output:​ 4-20mA 2-wire output capable of driving loads up to 600Ω

• Software Configurable:​ Range, fail-safe mode, and other parameters set via PC

• Visual Diagnostics:​ Per-channel LEDs indicate power status and fault conditions

• Linear Conversion:​ Converts resistance change to proportional 4-20mA signal

Applications

• Valve position feedback and control

• Level transmitter interfaces (float-type, displacer)

• Potentiometer-based position measurement

• Actuator position feedback in hazardous areas

• Mechanical position monitoring in process industries

• Safety instrumented systems (SIL 2 capable) for position measurement

Important Notes

1. The 5541 is specifically designed for 3-wire potentiometer inputs (0-1kΩ range)

2. Provides 0.5mA excitation current to the potentiometer

3. Configuration is required via MTL software to set resistance range and other parameters

4. The 4-20mA output is active and requires an external 24V DC supply for the output loop

5. Verify the potentiometer's resistance range and wiring compatibility
