12 channels 4-20mA analog input module

S3103 is a high quality and low cost analog data acquisition module. S3103 has total 12 channels input, each input has lightning and surge protection. Output use 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 is 4-20mA,fixed

l        Surge-protected Rs485 ensure reliability

l        The channel number is configurable, can be set up from 1 channel through 12 channel, 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        Isolated RS485, non-isolated RS485, RS232 for optional

l        You can tell us your requirement. we will update our firmware even after you received the modules ,you can update your modules through ISP.
