Product Introduction

Input: 2/3/4-wire PT100, tungsten-rhenium/B/S/N/K/J/T/E thermocouple, 4~20mA, 0~10V, 2~10V, 0~5V, 1~5V.

Output: 6-digit LED display, 4~20mA current range can be set arbitrarily, 0~10V voltage range can be set arbitrarily, relay switch quantity, RS485

Data update rate: thermocouple -1.2s PT100 -1s 4~20mA/0~10V-0.5s

Thermocouple cold end compensation accuracy (AT25℃): (maximum) ±0.05℃

Operating environment: -10~60℃ 0~90% relative humidity without condensation

Special function: Can be matched with the sensor to achieve ultra-high precision measurement. When thermocouple input, four-wire PT100 can be connected externally

Power supply: 220VAC/24VDC
