AD-KR 11 GX, AD-KR 12 GX, AD-KR 22 GX

Description

The coupling relays of series AD-KR 11 GX, AD-KR 12 GX (1-channel) and AD-KR 22 GX (2-channel) serve the galvanic separation and amplification of contact messages by means of a 24V auxiliary voltage. At the front, the operating condition of the relay is indicated via a red illuminated diode. A free-wheeling diode and a reverse polarity protection are integral. Due to the narrow type of construction, with an overall housing width of only 6.2 mm, a high packing density is achieved.

Application

Galvanic separation and amplification of contact messages.
