HE 5731 Operating instructions
10.1. Terminal extender current input / output
Danger of electric shock!
Electrical mounting only in de-energised state.
Damage to property through electrostatic charge!
Observe the safety measures specified in DIN EN 61340-51/-3 to avoid
electrostatic discharge!
Note!
Work on the electronic parts may only be done by qualified personnel.
Note!
Once the terminal extender is mounted, it cannot be removed again.
Note!
The external device (display unit or similar) which is connected, must
have a differential or a galvanically isolated current input. Otherwise, cor-
rect operation is not guaranteed.
In addition, there is the possibility that the 4…20 mA signal can be connected to an exter-
nal device. To do that, the device is switched in sequence with the 2-wire sensor. The
connection adapter for the analogue current input and output is plugged onto the existing
terminals 17–19.
The terminal extender can be purchased at HESCH (article number # 57310089).
This chapter only concerns devices that are designed to use an optional connection adapter.
