Sirina 22DO M

Sirina 22DO M is an actuator composed of 22 potential-free relay outputs (dry contact). Besides, manual control is added in order to test the outputs and LED indicators of the status and selection of them. For this, capacitive push-buttons are on the cover of the device, as well as LED indicators for selection and on/off of the outputs. Two arrows allow to move between the different leds referred to the corresponding output. Leds blink while signaling the output.; but when on is pressed, the led stops blinking for a second and start blinking again. On/off buttons open/close the outputs relay. Each output could work independently or simultaneously in different modes: binary outputs, blinds, fan-coils or thermo valves. It also has up to 8 arithmetic and logic units (UAL), as well as up to 8 timers/counters that allow programming complex logic operations, timings, counters, etc. Using internal or external variables.
