Introduction:
-
- Our DH48J is a digital down-counting and up-counting preset counting relay, once the relay count number reaches the set value (up-counting mode) or is zero (down-counting mode), the output contact will change from NO to NC or from NC to NO.
-
- When this counting relay is used for counting, it should be used with our NPN proximity sensor. When used with our inductive proximity sensor, it can count the number of metal objects. When used with a photoelectric sensor, it can count the number of any object.
- Besides, the input signal can be dry contact, such as button, limit switch and so on.
- The front panel of this DH48J counter is of international standard 1/16 DIN (48*48mm) size, and the installation method can be panel mounting or DIN rail mounting with relay socket.
- Working voltage can be AC110V, AC220V, DC12V, DC24V etc.
- Output contact capacity is 5 amps@220VAC, it is a dry contact, if you want to power a load, external power should be added to this contact.
