8 IN 8 OUT ON OFF Tapp 1 IN sonde temp Module
The DF8RIT module for Domino bus is a multi-function device, which integrates, within a single container, the following functions:
• 8 digital inputs for potential-free contacts
• 8 power relay outputs that can be configured for ON-OFF control of generic loads or in pairs, for the management of shutters, blinds and similar (only for AC motors with double winding)
• 1 temperature probe input, with a measuring range of -20 ÷ + 50 ° C, also suitable for the detection of both indoor and outdoor temperature
• Room temperature controller function with weekly programming (programmable chrono-thermostat, an operation identical to the Domino DFCT module)
