Mounting and Electrical Wiring
MODEL KEY
The device is mounted directly to the pipe / vessel via a G1/2"
PT = Pressure Transmitter
(standard manometer) process connection (size 27 wrench).
This process connection serves to fasten and secure the

A2 = 4...20mA (2-wire)
device in place. All mounting orientations are permitted.
A3 = 4...20mA (3-wire)
H =HMI
S =Standard
Pin Assignment of Plug
The plug is an A-coded, four-prong M12 plug (see Fig. 3).
