S5100 is a high quality and low cost analog data acquisition module with 10 relay normal open outputs. We keep contacting with customer when we develop this module to ensure it suit for field application. S5100 has total 8 channels input, each input has lightning and surge protection,has total 10 relay outputs . 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:
a) Surge-protected analog inputs with 12-bit resolution and 100k sample speed
b) Input can be any combination of 0-10V,0-5V,4-20mA,NTC 10K thermistor and dry contact
c) 10 channel normal open relay outputs, each output channel can be set AUTO/OFF/HAND by a 3-states switch
d) Surge-protected and isolated Rs485 ensure reliability
e) The channel number is configurable, can be set up from one channel through eight channels, improve sample rate for small count analog input
f) Standard ModBus protocol allows for up to 254 unique devices on one RS485 network
g) Can update your firmware via ISP through RS485 network
 

Application:
a) Remote data acquisition
b) Process monitoring
c) Industrial process control
d) Energy management
e) Supervisory control
f) Security systems
g) Laboratory automation
h) Building automation
i) Product testing
j) Direct digital control
