Function description relay output module
multisio 1D4-4RO ISO
The hardware of the multisio 1D4-4RO ISO supports 4 potential free relay outputs, 5 LEDs and an 8-fold DIP
switch.
The relay outputs serve to control contactors of bus devices or other systems.
The module can be accessed via a master device (multimax 3D6, multisio 5D6 or higher, or a computer with
VE via multisys 3D2-ESBS) using the module bus interface. The master device has to configure the module.
The operating voltage is supplied via the module bus interface. The module cannot be used on its own.
