Input Analog Universal 4-CH, Output Analog 2-CH 0-10V, Output Digital Open-Kolektor 4-CH, RS485/Zigbee, Modbus RTU

S7108 zigbee analog input, analog output, relay output PID control module is a high quality and low cost analog data acquisition module with one PID control. S7108 has total 4 channels input, 2 channels analog output and 4 channels isolated open-collector output . Each input has lightning and surge protection, the inputs can be any combination of 0-5V,0-10V,4-20mA,dry contact and NTC 10K thermistor. Analog output can output gradually through slew rate control and has default output when power up Output use RS485 or ZIGBEE wireless. Zigbee can realize the point-to-point, point-to-multipoint, multipoint-to-multipoint data transmission, can form a star, peer to peer and mesh network structure. Both of Rs485 and Zigbee using the industry standard Modbus protocol.
Highlights:

Surge-protected analog inputs with 12-bit resolution and 100k sample speed ADC
Input can be any combination of 0-10V,0-5V,4-20mA,NTC 10K thermistor and dry contact
The analog input channel number is configurable, can be set up from 1 channel through 4 channel, improve sample rate for small count analog input
Analog output can set power up output voltage and slew rate
All outputs can be controlled by PID
Any input can be set up link to PID
Reliable Zigbee can up to 3000 meters communication
Standard ModBus/RTU protocol allows for up to 254 unique devices on one  network
A lot of spare FLASH can be used to store user's parameters
RS232 /RS485 or ZIGBEE for optional
Can detect RS232/RS485 or ZIGBEE automatically, no need jumper
You can tell us your requirement. we will update our firmware even after you received the modules ,you can update your modules through Zigbee or RS232/RS485 .
