PHOENIX CONTACT
– The constant current circuits common in
process automation transmit the
measured values as a load-independent
current of 0(4)-20mA
– A voltage signal pick-off can be
implemented in the measuring line using
this terminal block, thus allowing the
signal to be used as an analog signal for
process computers
– The four-conductor connection permits
convenient wiring
– The lower level is assigned to the
measuring line while the upper level is
used for voltage pick-off via the 249
resistor
