S3402 has total 2 channel current and voltage output. The current and voltage can output at the same time. Can read back the voltage output to ensure the output take action.S3402 can output gradually through slew rate control and has default output when power up, all parameters store in nonvolatile RAM. Output BUS is RS485 with has surge protection. The modules are slave devices that can be easily controlled via the RS485 serial interface using the industry standard Modbus protocol.
 

Highlights:
a) Multiple output range setting, 0-10V,0-5V,0-20mA,4-20mA
b) The analog output can be read back
c) Jumper to select external power for current output for big load
d) Surge-protected and isolated Rs485 ensure reliability
e) Standard ModBus protocol allows for up to 254 unique devices on one RS485 network
f) You can tell us your requirement and we will update our firmware even after you received the modules, you can update your modules via ISP through RS485 BUS.
 

Applications:
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
