11 SERIES Light dependent relays 12 - 16 A Advantage of the “zero hysteresis” patented circuit: ensures reliable switching without wasting energy TYPE 11.41 “ZERO HYSTERESIS” LIGHT DEPENDENT RELAYS TRADITIONAL LIGHT DEPENDENT RELAYS OFF threshold ON/OFF threshold Switch OFF level = Switch ON level. Patented “zero hyseresis” circuitry ensures reliable switching without wasting energy. “Traditional” light dependent relays incorporate switching hysteresis to prevent malfunctioning or tripping. This results in an unnecessary delay in switching off, and a resulting waste of energy (over period...

11 SERIES Light dependent relays 12 - 16 A Switch-OFF time Switch-ON time NO Application examples Working as a standard light-dependent relay Working where lighting is not required from 10 PM onwards Working where lighting is not required between 1 AM and 5 AM Additional output - light dependent without time switch intervention All the functions and the values can be set through the front joystick and are displayed on the front LCD. Display mode During normal operation, with AC supply connected, the following is displayed: - he current time t - he current lux level (upper bars) t - he set...

11 SERIES Light dependent relays 12 Auxiliary output A solid state output at terminals Y1-Y2 is provided (rated 12 V DC, 80 mA/1 W max.): this can be used with the power module 19.91.9.012.4000 connected by the dedicated 011.19 connector. Or, it is possible to connect a suitable relay (for example, 38-48-49-4C-58-59 interface module) provided the coil is within the rating, and the wiring does not exceed 40 cm length. The auxiliary output is driven exclusively by the light sensor of the device, and is consequently independent of the time switch. With the main contact, this permits a flexible...
