L80
2 thermistor protection relays for alarm and fault
Option
L80
offers two thermistor protection relays (with PTB
approval) for PTC thermistors (type A) for warning and discon-
nection. The power supply for the relay and the evaluation is
provided within the converter.
An additional TM31 Terminal Module is integrated as interface
for further processing and to display signals.
Note:
Option
L80
cannot be combined with option
G61
(additional
TM31 Terminal Module).
