Digital inputs modul E12WEN16

• 16 galvanic separated voltage inputs 

• input voltage range 3 ÷ 50V 

• inverse input polarisation protection 

• power supply 12V DC 

• work controll and automatic restart system (!) 

• small size and possibility of easy install on standard bus 

• interface RS-485 (half-duplex) 

• MODBUS protocol 

• up to 19200 b/s, 8 data bits, no parity, 1 stop bit 

• possibility of easy adressing up to 127 identical controllers16 

Structure:
E12WEN 16 contains
 · input form unit - based on transoptors galvanic separating inputs from main unit; it adjusts also tested voltage to later interpretation as "0" or "1" 
· main unit - based on AT89C51 microcontroller - reads information about inputs status and transfer it to other system elements.

Use:
E12WEN16 may by used wherever needs to interpet voltage (current) signals status and transfer it by other systems or automatics units. Group of E12WEN16 may by used with output units and controllers, where long distance between them needs a lot of wires. Thanks to E12WEN16 system may by clearer and cheaper.

Attention:
There is necessary to inform what's the range of input voltage in order!.
