HC-RH-0018 OUTPUTS AND 8 ANALOGUE INPUTS MODULE
HC-RH-001 is a control module with 8 inputs and 8 independent outputs for general electrical equipment control.
Combines straightforward conventional input/output wiring with the expandability and flexibility of the Dallas 1-Wire™ bus.
Outputs support multiple modes: toggle, repeater (for an external dimmer), fixed timed operation or timing with early reset or restart, paired interlocked timed operation for automation drives, remote control, and more.
Pushbuttons and various sensors can connect to the inputs. HC-RH-001 adds multiple capabilities to conventional electrical installations and prepares them for home automation.
When home automation is enabled through a control unit, a bus fault leaves the basic installation working; only the home automation functions are lost.
The home can therefore still be used as with a conventional installation, reducing disruption and allowing maintenance to be scheduled rather than requiring immediate intervention.
Safety extra-low-voltage controls (inputs energised at 5 Vdc) improve electrical-installation safety.
Greatly reduces electric and electromagnetic fields in the building and is suitable for low-field electrical installations.
Technical specifications
