Zener Barrier Z787

Zener Barrier Z787Zener Barrier Z787 2 channel DC version, positive polarity Working voltage 26. 5 V at 10 A Series resistance max. 327 Fuse rating 50 mA DIN rail mountable With diode return The Zener Barrier prevents the transfer of unacceptably high energy from the safe area into the hazardous area. The zener diodes in the Zener Barrier are connected in the reverse direction. The breakdown voltage of the diodes is not exceeded in normal operation. If this voltage is
