BE/S4.20.2.1
Binary Input, 4-fold, Contact Scanning, MDRC
Product code:
2CDG110090R0011
The device interrogates 4 floating contacts using an internally generated scanning voltage. State inputs via 4 LEDs. Max. 4 signals (in 2 groups) are detectable. Each channel has one push button for manual operation.
Description
The 4-fold Binary Input BE/S 4.20.2.1 with manual operation is a modular installation device for installation in distribution boards. The device is suitable for detection of floating contacts. The pulsed scanning voltage is generated internally.
Buttons for manual operation, which can be used to simulate the input state are located on the front. The current status of the inputs is indicated via yellow LEDs. The device is ready for operation after connecting the bus voltage.
The Binary Input is parameterised via ETS. The connection to the KNX is implemented using the bus connection terminal on the front.
