FEATURES

With multi-channel temperature control function, one module

is equivalent to multiple temperature control meters, and

the temperature control parameters of each channel are

independent and do not affect each other.;

Multi-channel intelligent temperature control algorithm, can

achieve 4-channel accurate PID temperature control, can be

widely used in a variety of heating models;

With RS485 communication interface, standard modbus RTU

communication protocol, easy to communicate with PLC or

configuration screen, online monitoring of temperature data,

real-time control by the host equipment;

Modular structure design, optional multi-module splicing method,

multiple temperature control modules are spliced through the

side quick socket to achieve the effect of doubling the number

of channels, multiple 4-channel modules can be spliced into

8-channel, 16-channel and more temperature control channels;

The product has a high degree of integration and compact

size. The rail-type installation method is suitable for installation

places such as on-site control cabinets and power distribution

cabinets.;
