Customers can interface between CIE-H10 and dry contact sensors (switch, relays) by the following two methods.
What is dry contact?
A dry contact is a contact that does not provide voltage.
A. Using Dry Contact Adapter(DCA)
- Customers can implement dry contact interfaces very easily with Dry Contact Adapter (DCA).
- An Additional DC power is required for DCA.
- DCA will be provided from August 2009.
B. Implementing Dry Contact Interface
- CIE-H10's input ports sense DC voltage from sensers.
- Above 1.8V: 1(ON), Below 1.5V: 0(OFF)
- Therefore, users have to implement as vollowed for Dry Contact Sensors.
- DC valtage of input port is DC 1.8V ~ 24V. But we recommend users to use a DC 5V ~ 24V power supply because of cable resistance.
- We recommend users to use isolated DC Power.
