3:signal output :one channel standard isolation RS485 output

            One channel isolation isolation 4-20mA or 0-20mA active output.

            One channel OCT output(programmed between the pulse width(6-1000ms),default before out of factory (200ms))

            One channel isolation relay output,with positive,negative,net accumulation pulses and different alarm signals.

4:signal input: two channel three wire system PT100 platinum resistor input loop,to make calorimeter has the function of displaying heat quantity.

             Three channel 4-20mA input optional,accuracy:0.1%,has the ability to input the signals of pressure, liquid level, temperature and so on.

5::display:2*20 backlit LCD(Chinese and English optional)

6:operating:4*4 tactile keypad or magnetic 4 keypads operating(F4 mainframe)

7:other functions:automatic memory the positive,negative,net totaliser or flow rate and thermal energy of the last 512 days,128 months,10years

             Automatic memory the time of power turning on and off and flow rate of the last 30 times, realize to compensate by hand or automatically,read the datas through Modbus communication protocol.
