40-Channel 10K NTC Thermistor 4–20mA Analog Input Module – RS485 Modbus RTU

S5140 is a high quality and low cost analog data acquisition module with 40analog inputs.  each input can be0-5V,0-20mA,thermistor,dry contact,open-collector input,It also accept 0-10Vinput but need a external resistor. Output is RS485 BUS with surge protection,to reduce interference by serial port communication, the output isolated byhigh speed opto-couplers. The modules are slave devices that can be easilycontrolled via the RS485 serial interface using the industry standard Modbusprotocol. Highlights:l  Surge-protected analog inputs with 12-bit resolution and 100k samplespeedl  Input can be any combination of 0-5V,4-20mA,0-10V,NTC 10K thermistorand dry contactl  Surge-protected and isolated Rs485 ensure reliabilityl  The channel number is configurable, can be set up from 1 channelthrough 40 channels, improve sample rate for small count analog inputl  Standard ModBus protocol allows for up to 254 unique devices on oneRS485 networkl  A lot of spare FLASH can be used to store user’s parametersl  Islated RS485, non-isolated RS485, RS232 for optionall  Can update your firmware via ISP through RS485 network

InputsEach input can be jumper-configured in 1 of4 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 10KNTC, but can custom according to your sensor type
