RS485 master port 1, used for connecting other RS 485 slave device and instruments
RS485 slave port 1, used for connecting remote 485 master or PC API access to the device
Current ADC channels 8, used to sample 4-20 mA analogue current signal (common pin shared with analogue voltage ADC channels)
Voltage ADC channels 8, used to sample 0-5V analogue voltage signal (common pin shared with analogue current ADC channels)
Counter sampling input, 2 channels, used for pulse counting signals (common pin shared with digital input channels)
Digital signal input channels, 8, used to sample digital voltage signal
Solid state relay output 8 channels, used for environmental control actuation. 4 out of which are common pins for 4 PWM channels
IO ports are separate from CPU with photo-electrical couple protection, and the maximal IO input endurance voltage is no less than 24VDC.

egPLC5888 power supply is designed with extra wide range, it can be operated normally between 6VDC and 24VDC
