The freely programmable Saia PCD1.G1100 module allows you to control light and shade, either as an independent miniature controller or as a module in conjunction with a higher-level controller. It has four digital inputs as well as two analogue and two relay outputs. The relays can be used either to switch two light groups directly or to control a blind. You can also position blinds and localize faults using the integrated load current measuring system. The digital inputs also allow you to connect electrical push buttons.
