OMRON E5L-A Analog Electronic Thermostat

Overview

OMRON E5L-A is an analog setting electronic thermostat from OMRON E5L series. OMRON E5L-A adopts thermistor temperature sensing and ON/OFF two-position control, equipped with SPDT relay output that can directly drive heating or cooling loads. This OMRON E5L-A is widely stocked as spare simple temperature control unit for embedded equipment temperature control assemblies.

Features

OMRON E5L-A uses rotary dial for temperature setting and separate differential adjustment knob for hysteresis setup. It has no digital display, only power and output status indicator lamp. It supports multiple temperature range versions including -30~20℃, 0~50℃, 0~100℃ and 100~200℃. E5L-A is plug-in design, compatible with PTF14A or PTFZ-14-E socket for DIN rail or panel mounting. The relay output reaches 10A at 250VAC resistive load, capable of direct switching of small heaters and cooling fans. Matching thermistor sensor is supplied together for quick installation. This thermostat consumes approximately 3VA, accepts wide AC input voltage from 100VAC to 240VAC. It is CE compliant, designed for 24/7 continuous operation on packaging machines, test equipment, small ovens, refrigeration units and industrial embedded devices.

Specifications

OMRON E5L-A Analog Electronic Thermostat Brand: OMRON Model: E5L-A Series: E5L Type: analog setting electronic thermostat Input: thermistor sensor Control method: ON/OFF two-position control Output: SPDT relay, 250VAC 10A resistive load Power supply: 100~240VAC 50/60Hz Power consumption: approx 3 VA Setting: rotary dial temperature set, differential adjustment Indication: status LED only, no digital display Mounting: plug-in socket PTF14A PTFZ-14-E, DIN rail Dimensions W × H × D: 45 × 35 × 75 mm Ambient temperature: -10℃ ~ +55℃ Ambient humidity: 25% ~ 85% RH Status: classic OMRON simple temperature control spare

Principle

OMRON E5L-A detects temperature change via thermistor resistance variation. This Analog Electronic Thermostat compares the measured temperature with the dial preset value. When temperature crosses the threshold, the internal relay switches state to turn on or off the heating or cooling load. The differential setting prevents frequent relay chattering caused by small temperature fluctuation.

Applications

OMRON E5L-A is deployed in small oven, chiller, packaging equipment, test bench and industrial machinery embedded temperature control. It provides simple ON/OFF temperature regulation for heating and cooling loops. OMRON E5L-A is stocked as spare electronic thermostat for industrial temperature control assemblies.
