INTRODUCTION TO MODULE CONV 4/420/A AND CONV 8/420/A
Add-on module CONV 4/420/A interacts via serial mode through 2 wires with NT935 moni-
toring device and it allows to take from output 4 4-20mA current signals referred to the 4
meter channels.
CONV 8/420/A has been designed for connection to NT538 monitoring device in order to
take 8 4-20mA current signals.
Opto-insulated serial connection between NTXXX and module.
To each NT935/NT538 monitoring device is possible to connect many add-on module.
For instance it will be possible to have an optioned monitoring device with 4.20 mA
outputs, relays bank for each channel and ModBus RTU interface simultaneously.
