◼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.；

|
SSR1 |
The solid-state drive signal output of channel 1, the positive and negative electrodes need to be distinguished |
|
AIN1 |
The analog input of channel 1, the default is 4-20mA signal, the positive and negative electrodes need to be distinguished |
|
AOUT1 |
The analog output of channel 1, the default is 4-20mA signal, the positive and negative electrodes need to be distinguished |
