Universal Multi-Channel Process Indicator/ Controller | Up to 4 Channels

The Universal Multi-Channel Process Indicator is an advanced, modular instrument designed to measure and display multiple process parameters across a wide range of industrial environments. Built with modern SMT technology, it ensures low power consumption, high accuracy, and long-term stability.

This unit supports 1 to 4 input channels, allowing operators to monitor several signals simultaneously. With a bright dual 4-digit LED display, users can easily switch between channels or fix a display to a specific input. Inputs are fully programmable for thermocouples, RTDs, mA, and VDC signals, making it a flexible solution for diverse industries.

For seamless integration, the device provides multiple output options, including 4–20mA, relay, RS485/RS232 communication with MODBUS-RTU protocol, and a 24VDC auxiliary power supply. Additional features like built-in cold junction compensation and digital filtering ensure stable and accurate performance.

Ideal for industrial automation, process monitoring, and SCADA/PLC/DCS integration, this indicator provides a dependable solution for multi-channel measurement.
