Industrial products: STAGER (PILOT DISTIBUTOR) : TUYA electra n.a/n.c :

Pilot distributor TUYA electra n.o./n.c.
membrane chambers double effect

TUYA electra n.o./n.c.:

commands the membrane chambers double effect (pressure for opening and pressure for closing).

The beginning of the regeneration and the duration of the various phases are established by a programmer or PLC.


Connection for six membrane chambers, six programmable phases pilot  (5 phases of the regenertaion).


Uscite a relais (n.o. / n.c.):

REL0: processingl processing or general alarm signal
REL1: TUYA in phase 1 signal
REL2: TUYA in phase 2 signal
REL3: TUYA in phase 3 signal
REL4: TUYA in phase 4 signal
REL5: TUYA in phase 5 signal
Analog output
