Warming function at the same time
By making the arrival time of the multi loop consistent, uniform temperature control function.
It can control temperature uniform, to ensure that the control object no local burning or thermal expansion LJ51AW12AL PDF.
No idle running, with energy saving effect, can reduce operating costs.
Can make multi loop to reach the target value (SV) of the same time.
By setting the simultaneous heating of the channel group, up to 2 groups of units, respectively, at the same time warming.
It is very effective to use the control object that does not want to heat up to the time of arrival error LJ51AW12AL PDF.
Applicable to a variety of systems.
Sampling period switching function.
Sampling period can be selected from 250ms/4ch and 500ms/4ch.

1, the switch quantity acquisition and switch control and RS-485 bus are isolated from each other, and isolated from the whole system.
2, the power supply line has anti reverse connect function, once the wrong power line,
Will automatically cut off the power to protect the entire module is not damaged.
With over-voltage protection function, when the voltage is too high, automatic disconnection,
Protecting the entire module is not damaged.
3, RS-485 interface with 600W lightning protection and surge protectiion function, with 3000V photoelectric isolation LJ51AW12AL datasheet.
4, the use of Modbus protocol, good general, can be very convenient and other systems,
Customers can also according to their own personal needs, custom related agreements, convennient and flexible LJ51AW12AL datasheet.
5, communication lines using RS-485 bus, support for multiple modules in parallel use,
Easy to expand the system, good scalability.
