S5102 is a high quality and low cost analog data acquisition module with 8 analog inputs. Each input can be 0-5V,0-10V,0-20mA,thermistor,dry contact, open-collector input,2 channels 0-10V analog output,6 isolated digital input and 12 channels normal open relay output. The digital input can be dry contact, wet contact and open-collector, each input also can be 32-bit counter.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, open-collector and dry contact
l The channel number is configurable, can be set up from 1 channel through 8 channels, for analog input and set up from 1 to 6 for digital input, improve sample rate for small count input
l 2 channels 0-10V analog output with high accurate reference chip
l Isolated digital inputs can be configured as counter input, total 32 bits,1000Hz
l Total 12 channels relay output,mormal open contact
l Surge-protected and isolated Rs485 ensure reliability
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 Can update your firmware via ISP through RS485 network, can provide any hex file to help you finish some logic control
