Contact protection element
Connect a contact protection element to the relay output terminal of the instrument for noise removal.
Make sure to connect to the load via a buffer relay or contact protection element for relay outputs such as
ON-OFF pulse, ON-OFF servo and event outputs.
We prepare the following contact protection elements. Use one if necessary.
Model Specification Open/close current Application
CX-CR1 0.01μF + 120Ohm 0.2A or less Light loads
CX-CR2 0.5μF + 47Ohm 0.2A or more Heavy loads
Note that a leak current is generated as shown below when the contact protection elements are used,
depending on the load power supply.
