12Bits 8 inputs 100k sps and 10 dry contact outputs,has ISP fearture

Surge-protected analog inputs with 12-bit resolution and 100k sample speed

10 channel normal open relay outputs, each output channel can se set AUTO/OFF/HAND by a 3-states switch

Surge-protected and isolated Rs485 ensure reliability

The channel number is configurable, can be set up from one channel through eight channels, improve sample rate for small count analog input

Standard ModBus protocol allows for up to 254 unique devices on one RS485 network

Can update your firmware via ISP through RS485 network

Inputs
Each input can be jumper-configured in 1 of 4 ways
 0-5V signal
 0-10V signal
 0-20mA signal
 Dry contact, 10K thermistor
Each input has a corresponding LED which will light up if the value of input is greater than 50% full range of input.
Outputs
The state of each output is determined by its corresponding switch position. The switchs have 3 states-'HAND', 'OFF', and AUTO'. When switched to 'HAND', the corresponding relay output will be  switched on contacts closed .When switched to 'OFF', the relay output will be set to open contact. When switched to 'AUTO', relay outputs be determined by the value stored in the corresponding MODBUS register, 0 = open contact and 1 = close contact.
The output registers are stored in RAM, thus the contents of each register will be lost upon power-off. Each output has a corresponding LED which will be light up if the relay is closed.
