16 Channels Isolated Digital Input Module, Modbus/TCP protocol

S3302I has total 16 channels isolated wet contact or dry contact or open-collector input, Each input channel also can work as 32-bit counter input, the maximum frequency is 100Hz for total 16 channels and 1000Hz for only one channel. Output BUS is RS485 with has 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) Isolated digital inputs can be configured as counter input, total 32 bits
b) Static and lightning protection for each input
c) The input channel number is configurable, can be set up from 1 channel through 16 channels, improve frequency for small count input
d) Surge-protected and isolated Rs485 ensure reliability
e) Standard ModBus protocol allows for up to 254 unique devices on one RS485 network
f) Tell us your requirement, we will update our firmware even after you received the modules ,you can update your modules via ISP through RS485 BUS.
 

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
