CHDS4 universal process indicator


1/16 DIN Universal Process Indicator

Single loop Universal Process Indicator & Controller CHDS4 receives temperature, flow rate, pressure, and other types of measurement readings from sensors & transmitters, and sends corresponding signals to your PLC for controlling. With a intuitive interface to program range and decimal point through the keypad, CHDS4 allows inexperienced instrumentation operators easy installation and start-up to most processes. 



Aposun brand Universal Process Indicator CHDS4 combines, in one compact and convenient 1/16 DIN enclosure, a high precision microprocessor-based analog circuit with a very simple configuration interface to monitor a wide range of analog variables.

Process indicators & control units for all industries:

  • Use with any 4-20mA output sensor where there is a process to measure and control
  • Metals and mining
  • Water and wastewater
  • Oil and gas
  • Tank Level Monitoring & Control
  • Remote Pressure Indication
  • Pulp and paper

Main Features

  • The display is available with red & green LEDs
  • The 1/16 Din case meets NEMA 4X(IP65) specifications from the front when panel mounted
  • This low-cost tough versatile process indicator is compatible with most common thermocouples, Pt100 RTD and linear as 4 to 20 mA and mV.
  • With an intuitive interface to program range(-1999~9999) and decimal point through the keypad
  • Loop powered process indicator: 12V or 24V DC for external signal conditioners
  • Sampling speed: 6~8times/sec.
  • Built-in thermocouple automatic cold junction compensation
  • Non-Volatile Memory: All programmed settings are stored in nonvolatile memory for a minimum of ten years if power is lost.
  • Any setup functions can be locked out for simplified usage and security.
  • Digital panel indicator with control function (limit value monitoring, mathematics, differential pressure and linearization,…)
  • Process indicators for panel mounting as well as for field mounting
  • Simple menu and easy wiring, user-friendly
