Global Caché Contact Closure Sensor
|
|
|
|
|
The GC-SC1 detects the open-and-closed status of a pair of isolated contacts, such as a relay or switch. It is ideally suited for detecting contact closure on drapery controllers, thermostats, security contacts, and door strikes. The GC-SC1 filters out false triggers associated with typical contact bounce. The device can be plugged directly into the Global Caché GC-100 Network Adapter connecting the sensor to the network. Additionally, the GC-SP1 will work with other controllers that provide 5V power and accept digital logic (TTL) input. The GC-SP1 connector is a standard 3.5mm stereo jack.

Features:
- Detects the open-and-closed status of a pair of isolated contacts or the state of open collector devices
- Ideal for detecting contact closure from relays, switches and bush buttons. Can also be employed to determine the state of open collector devices used on digital controllers and current sensors.
- De-bounce logic is provided to prevent multiply false signals created by contact bounce. A contact or switch must be closed ≥ 3mS before an output is indicated. A contact must remain open for ≥ 50mS before an output is not indicated. This asymmetric reaction time provides fast indication of a contact closure while filtering out subsequence contact chatter or bounce.
- Power supply is not required when used with the GC-100
- Cable/Connector – 6 feet, 3.5mm stereo plug
