multisio D6-ESBS-4RO-ISO

Additional module for the multimax energy optimization system

 multisio D6 ESBS 4RO ISO 1


The multisio D6-ESBS-4RO-ISO-1 with eBus hardware supports four floating relay outputs (changeover relays).

The relay outputs serve to control contactors of devices or other systems.

The module can be accessed from a master device (multimax D6-5, multisio D6-7 or higher, or a computer with visual energy via multigate ESBS) using the module bus interface. The master device has to configure the module. The module cannot be used on its ownThe bus interface is powered via a power supply (of Ph-N 100V – 240V+/-10% 50Hz/ 60HzAC or DC) or the module bus interface (24 VDC). The device is equipped with a "power"LED for supply voltage monitoring.
