This intelligent threshold detector/transmitter with an extra large display is
specifically designed to monitor limit values or an ON/OFF or continuous
control loop.
Two versions are available: the 8400 Compact and 8400 for wall mounting.
The wall-mounted version must be inserted into a holder previously mounted
on a wall, and it must be associated with a remote temperature sensor.
The switching points can be programmed with keys directly in the display or
optionally with a 4...20 mA standard signal input from an external PLC. As an
option, the process value can additionally be transmitted to the PLC (with a
4...20 mA signal).
The connection of the 8400 to the process in the piping is made using standard
T-fittings with standard connections (G ½).
