Counter / Raster Table

1、 Overview

Integrate display, control, transmission and other functions Input thermocouple, thermal resistance, standard current, standard voltage signal, display and control

Make physical quantities such as temperature, pressure level, rotating speed, pH, PH value, etc.

Counter is widely used in thermal, chemical, electromechanical equipment, municipal engineering

Building automation and other industries are ideal products for various automatic control systems.

2、 Features

Modular design, SMT process, high-performance switching power supply

19 kinds of signals are compatible with input, and the range and decimal point can be set and corrected at will

Input signal can be selected arbitrarily, and thermocouple input comes with cold junction temperature compensation

Isolated current and voltage transmission output (12-bit resolution), output range can be set arbitrarily

Two relay outputs, each relay can be set to the upper limit or lower limit freely

Limit control, relay pull-in value and release value (return difference) can be set arbitrarily
