|
The UTP controller drives two galvanically isolated groups of 8 loads each with 24 - 230 VAC TRIAC (solid-state) switches.
Typical loads are firedamper actuators/motors, warning lamps, contactors etc. The outputs switch in synchronisation with the AC supply to minimise turn-on (in-rush) currents, load stress and generated noise.
The controller interfaces to external systems with its fully protected 12 bit inputs and 8 bit outputs. |
The outputs are galvanically isolated NPN optotransistors and the inputs are NPN sinks at the controller potential.
The UTP controller can also supply local automation devices with unregulated 15 VDC.
