The ERO ELECTRONIC LMS491130000 01.06 is a robust and compact DIN rail-mountable temperature controller designed for simple and reliable process control in industrial environments. This single-channel controller is part of ERO’s reliable LMS series, known for its ease of use and precise regulation.
Its primary function is to maintain a set temperature by monitoring a process via a PT100 temperature sensor and switching a connected load (like a heater) using its built-in relay. The “01.06” variant specifies a key configuration: a 6A relay output, making it suitable for controlling loads with moderate power requirements.
Key Features & Benefits
-
Precise PT100 Sensor Input:Â Accurately measures temperature using a industry-standard PT100 (3-wire) platinum resistance thermometer, ideal for a wide range of applications.
-
Compact DIN Rail Design:Â Easily installs on a standard TS35 DIN rail, saving space in control panels and electrical cabinets alongside contactors, circuit breakers, and other automation components.
-
Clear LED Display:Â Features a bright, easy-to-read LED display that simultaneously shows the setpoint (SV) and actual process value (PV).
-
Simple Setpoint Adjustment:Â Intuitive operation with buttons for setting the desired temperature and configuring basic parameters.
-
6A Relay Output (SPDT):Â The built-in 6-ampere single-pole, double-throw (changeover) relay can directly switch heaters, contactors, or small motors. The relay output is indicated by a clear LED.
-
PID Control Algorithm:Â Provides stable and accurate temperature control by minimizing overshoot and offset, ensuring energy efficiency and process consistency.
-
Configurable Alarm Function:Â Includes one programmable alarm output that can be set for various conditions (e.g., high-temperature alarm, deviation alarm), enhancing process safety.
-
IP40 Protection Rating:Â The front panel offers basic protection against accidental contact with live parts, suitable for installation in controlled industrial environments.
