The QCP-50000 Series Multi-Channel Control Panels are control panels to house the QAS-10000 series plug-in controllers with solid state sensors, or the QAS-11000 / QAS-51000 series plug-in controllers plus any 4-20 mA transmitter by QEL or by others. Each controller card slides into the panel along guide rails. The control panel is available in 2, 4 and 8 controller card capabilities, and comes with blank plates for any unused
channel slots. The panel requires 120 VAC power which in turn powers each controller card.
