Color LCD Display Temperature Controller is an industrial process control instrument designed based on measurement and control technology.Color LCD Display Temperature Controller features high measurement and control accuracy, as well as a power-on alarm exemption function.
Full 5-digit data display enables real-time insight into each process control parameter, with a display range of ±99999.
Dual communication channels: one for MODBUS RTU communication and one for MODBUS TCP Ethernet communication.
Communication data supports the 16-bit integer standard. When the data range exceeds 16 bits, an offset address method is adopted to realize 32-bit integer data reading and writing, achieving high-precision, full-resolution real reading for process control.
Equipped with 24-bit high-speed multi-channel synchronous data acquisition and a 32-bit RISC instruction set industrial-grade microprocessor, it offers strong anti-interference capability and fast response speed.
The control output refresh rate is 50ms, adapting to faster control processes.
4 channels of hard-contact alarm output and program end alarm output; 9 channels of programmable DIO (Digital Input/Output) functions-each IO can be customized as input or output according to requirements. By combining relays with DO (Digital Output) applications, up to 13 alarm channels can be implemented.
Supports program curve cycling.
Program curves can control the on-off output of 9 channels of open-collector digital signals.
5 groups of grouped PID output limiting control, meeting the requirements of various control working conditions.
Supports input of 47 types of industrial standard sensor signals, as well as non-standard signal input and multi-point linearization processing.
