CTR 8

The Extron CTR 8 adds contact closure control to most RS-232 controllable Extron single-output simple or scaling switchers, or to an Extron IP Link control processor. The CTR 8 accepts up to eight contact closure inputs and converts them to SIS™ serial commands that select the corresponding input on an Extron switcher or allows the CTR 8 inputs to be controlled by an Extron IP Link control processor. Video can be muted and un-muted by pressing a single switch in sequence, allowing the user to control the viewing of the presentation. Each contact closure input features a +5 VDC output that can be used to light an LED to indicate the active switch. To streamline installation, a +12 VDC power loop-out port allows sharing of external power with another Extron product.

The CTR 8 is ideal for applications in which contact closure control must be added to an Extron switcher or control processor. The CTR 8 is housed in a compact 1U, quarter rack width metal enclosure. It ships with the Extron MBU 123 low-profile mount kit for installation under tables and lecterns, or for mounting behind displays.
