SmartRelay 3 system
5.3 SmartOutput module
(Manual)
NOTE
Too low operating voltage
When selecting the power supply, please allow for a voltage drop occurring
in conductors. A voltage drop can cause the operating voltage in the reader
to fall below the required level and malfunctions may occur. In such a case,
either the operating voltage on the controller needs to be increased or the
reader equipped with its own power supply unit.
A multi-coloured LED signals the different operating modes.
SmartOutput modules are ideal complements to controllers if more than
one relay output is required. Every SmartOutput module is equipped with
eight relays, which each feature a change-over contact. SmartOutput
modules can be connected in parallel to one another and fitted on a DIN
rail (35 mm x 7.5 mm).
Up to 15 modules can be connected. Only four outputs are available on
module 15 (up to 116 additional outputs in total).
A multi-coloured LED signals the different operating modes.
NOTE
Follow the switch-on sequence
After a power-on reset (power outage followed by restoration of power
supply), the controller automatically searches for connected system com-
ponents one time on restarting. System components which are not sup-
plied power until the controller restarts are thus unable to respond to the
controller's query and are not recognised.
The controller must therefore be supplied power with the other system
components at the same time or must be the last system component to
receive power.
