Function
Presigo PDTX…-C is a range of pressure transmitters equipped with one
or two pressure sensors, two universal inputs, two universal outputs and
an RS485 port for Modbus communication. It operates as a Modbus
slave.
This range of pressure transmitters is especially well suited as distributed
I/O modules for air handling unit controllers. They are designed for easy
installation together with Regin’s Corrigo or EXOcompact controllers.
