2-RELAY ACTUATOR ITEM F430/2
By means of internal relays, this device executes the commands received
from the control unit or the sensor. It is needed to control loads such as
motorised valves, pumps and electric radiators.
It has two independent relays which can be used to command two distinct
loads with ON/OFF function and to command a single load with open/close
function. To manage open/close loads the actuator must be confi gured with
the logic interlock of the two relays and contact C1 must be considered
for the opening command and contact C2 for the closing command (see
“Confi guration” section).
LEGEND
1) Load forcing key: pressing this key activates the loads connected to the
actuator. To activate the load its sensor must be kept unconnected.
2) Light indicator: signals that the relay contact is closed.
3) BUS: connection for bus cable
4) Configurator socket: housing for the configurators
