8.1 Connection of the hand-held-terminals HHT
The FSK transmission versions of the isolation transformers
SINEAX SI 815-1122. and SI 815-1222. can relay a frequency
modulated digital signal in both directions in addition to the
analog signal and the auxiliary supply. Connect the hand-held
terminal HHT as shown in Figures 10 and 11.
The burden of the signalling circuit must be as
least 250 Ω. The burden is represented in Figures
10 and 11 by the resistor R

9. Commissioning and maintenance

The device is in operation as soon as the input signals E1...
E2 are connected.
The signal isolator requires no maintenance.
