S5140 is a high quality and low cost analog data acquisition module with 40 analog inputs. each input can be 0-5V,0-20mA,thermistor,dry contact,open-collector input,It also accept 0-10V input but need a external resistor. Output is RS485 BUS with surge protection, to reduce interference by serial port communication, the output isolated by high speed opto-couplers. The modules are slave devices that can be easily controlled via the RS485 serial interface using the industry standard Modbus protocol.
Highlights:
l Surge-protected analog inputs with 12-bit resolution and 100k sample speed
l Input can be any combination of 0-5V,4-20mA,0-10V,NTC 10K thermistor and dry contact
l Surge-protected and isolated Rs485 ensure reliability
l The channel number is configurable, can be set up from 1 channel through 40 channels, improve sample rate for small count analog input
l Standard ModBus protocol allows for up to 254 unique devices on one RS485 network
l A lot of spare FLASH can be used to store user's parameters
l Islated RS485, non-isolated RS485, RS232 for optional
l Can update your firmware via ISP through RS485 network

Dry contact wiring diagram
Input 1 to 40 can be configure as dry contact, open-collector input, AGND is common terminal for these input signal
Thermistor,0-5V,4-20mA input
The thermistor can default is 10K NTC, can custom other type thermistor.
0-10V analog input,need a external 250R resistor.
Inputs
Each input can be jumper-configured in 1 of 4 ways
² 0-5V signal
² 0-10V, need a external 250R resistor
² 0-20mA
² Dry contact, thermistor, open-collector. thermistor default is 10K NTC, but can custom according to your sensor type
