DST-815 thin temperature transmission isolator

Classification:

Thermocouple, resistance input

DST-815 thin temperature transmission isolator will be on-site thermal resistance or thermocouple signal after isolation amplification processing, converted into linear with the temperature of the DC signal output to the control system, used as a thermocouple temperature transmission, with cold junction temperature automatic compensation function. The parameters can be modified by the supporting upper computer software, which can be used with the unit combination instrument, DCS, PLC and other systems to provide field instrument signal isolation, signal conversion, signal distribution, signal processing, etc., so as to improve the anti-interference ability of the automatic control system of industrial production process and ensure the stability and reliability of the system. This product variety is divided into one in and one out, one in and two out, two in and two out, and the input and output magnetic isolation.

Keywords: Isolator

• Single channel, dual channel This series of varieties have one in and one out, one in and two out, two in and two out, four in and four out. • DC voltage, current, thermal resistance, thermocouple input • Analog output for power distribution • The signal type and test range of some products can be programmed by the supporting PC software • Input/output/power magnetic isolation Transmission accuracy (20 ℃):0.1%FS • Short response time, thin thickness, low power consumption • Plug-in terminals for easy installation and maintenance • Standard 35mm DIN rail clip-on mount
