Description

16ch Binary Input (potential-free)

The binary input has 16 inputs available and is used to connect eight conventional push-buttons or floating contacts such as window or relay contacts. There is one status LED for each input. In addition, the input status is sent to the bus. A separate power supply is not necessary

Technical Data:

• 16 Inputs (potential-free / floating contacts)
• wire length tested 30m (more possible)
• x-Inputs can configure to a "room" ("room"-GA can show if one of the windows is open in the room)
• Counting of pulses, suitable for 30ms S0 pulses (CH13 -CH16 can use for S0)
• The device makes a contact supply voltage (5V) which is not electrically isolated from the bus voltage!

Nom. Rating

• input voltage 5V
• min voltage to detect an HIGH level on an input = 3V

Max Rating

• max input voltage 24V (only for a short time = 20s)
