DX series LCD Display Temperature Controllers

The DX series temperature controller adopts an easy to read LCD display screen and is an intelligent digital temperature controller developed by NIETZ company.

This model features large white PV characters. Use 11 segment code to display PV and SV alphanumeric characters, improving readability. The temperature controller has a high-speed sampling period of 50 ms and a display accuracy of ± 0.3%. Space saving design, 45 mm depth, easy to install in limited space (DIN 48 x48 mm model). The DX series can be configured and monitored on a PC through RS485 communication, and offers multiple sizes for flexible installation in various environments.

Features
  • 3 dimension: 48x48mm (DX4M); 48x96mm (DX4H); 72x72mm (DX4C)

  • 50ms high-speed sampling and ± 0.3% display accuracy

  • Large LCD display with easily readable white PV characters

  • SSR driver output/current output/relay output can be switched
