Pulse divider/preselection relay RD53

Preselection relay / pulse divider
Digital adjustment between 2 and 999
Pulse inputs for contact, NAMUR or NPN transistor.
Transistor output for connection to “slave module”
1-pole relay output
DC supply or AC supplies up to 230 VAC
Made in accordance with the
and EMC regulations
C-mac® module type RD53 is a digital pulse counter module, selectable as pulse divider or preselection relay.
The pulse inputs can be activated from a mechanical contact, a transistor or a NAMUR sensor, and the reset input
can be activated from a mechanical contact or a transistor.
The unit is supplied with a “slave” transistor output, in
this way several units can be connected to the same pulse
sensor.

8 A - 250 VAC, ohmic load
