KR 5 A
-for signalling a limit level (1 contact) or
-for two-point control (2 contacts)

Alternative supply voltages
AC versions : terminals 15 + 16;
DC versions :
terminal 15 = -
terminal 16 = + :
- AC 230 V (delivered if no other supply voltage is specified in the order) or
- AC 240 V or
- AC 115 V or
- AC 24 V

- DC 24 V or
- DC 12 V (in these two cases, the unit must only be connected to a low safety voltage
which corresponds to the safety regulations relating to the application)

- further supply voltages on request
