Configured as RS-232 according to the demand of client),communication
Power input range 9-24V,power output including 12V/2.5A,4V/2.5A, 3.3V/2.5A
Power voltage Can collect the external supply voltage and the internal standby supply
acquisition voltage.
Analog input 4 channels;External signal range:0~5V or 4~20mA;Acquisition accuracy 16
bits (0.08 mV or 0.3 uA),the acquisition circuit can be configured as voltage mode or current mode via wire jumper or resistor
Digital input 4 channels, can be configured as active or passive input via resistor,
adopting interrupt I/O port, can collect the level and pulse signal
Digital output 4 channels, can be configured as the relay output mode or transistor
output mode via wire jumper, the max load are respectively (10A/250V AC)
and (500mA/12V DC)
