4 relays DIN actuator 6 A
038 44
Description
Actuator for installation in DIN rail distribution boards or switchboards. This device
incorporates four independent relays with a common terminal, for the activation of
four loads, with local control pushbuttons for each individual load.
If two adjoining positions (e.g. PL2 and PL3) are assigned the same configurator, the
actuator may set two to four relays in interlocking mode, for the control of loads
such as rolling shutter motors, curtain motors etc. If all PL positions have the same
configurator, the actuator will have four relays for the motorised rolling shutters.

Technical data
Power supply from SCS BUS: 18 – 27 Vdc
Consumption: 40 mA (single loads),
22 mA (interlock)
Power/Absorption of driven loads:
- Incandescent lamps:
500 W @ 2 A
- Resistive loads:
1400 W @ 6 A
- Fluorescent lamps:
70 W @ 0.3 A
- Electronic transformers:
70 W @ 0.3 A
- Ferromagnetic transformers:
500 VA @ 2 A ϕ 0.5
- Motor reducer for rolling shutters: 500 W @ 2 A
Power consumption with max. load: 3.2 W (1)
NOTES:
1) the power dissipated indicated is that corresponding to the device with
all the relays loaded at the load maximum. If the load is less the dissipated power is less and may be calculated by means of the following formula:
P[mW]=140+400*N+10*[I12+I22+...IN2]
P: dissipated power in mW
N: no. of loaded relays
IN: load current corresponding to the N relay.

Configuration
A PL1 PL2 PL3 PL4 M
The actuator performs all the basic operating modes which can be configured directly on the control. Moreover further operating modes with the configurator in position M of
the same actuator are listed in the table below.
Possible function
Configurator in M
Timed stop for motorised rolling shutters. The actuator deactivates after the set time has elapsed1)
This mode only operates if PL = PL...+1 (same configurators), and therefore with two interlocked relays.
none – 9 (1)
Timed stop for motorised shutters. The actuator deactivates after the set time has elapsed. This mode only
operates if PL1 = PL2 = PL3 =PL4, with coupled relay interlocking. 2)
none – 2 (2) or equal to 9 (2)
Actuator with Slave. It receives a control sent by a Master actuator with the same address.

NOTES:
(1) The value of the configurator in the table defines the final time, after which the
actuator deactivates.
EXAMPLE 1
A= 1; PL1= 3; PL2= 5; PL3= 5; PL4= 2; M= none
In this case the relays (PL1) and (PL4) are activated on the basis of the mode defined
by the controls configured A=1 PL=3 and A=1 PL=2. Relays (PL2) and (PL3) are interlocked and are activated by control A=1 and PL=5 with mode defined in M. Relays
(PL2) and (PL3) deactivate after a minute.
EXAMPLE 2
A= 1; PL1= 3; PL2= 2; PL3= 4; PL4= 6; M= none
In this case all the relays (PL...˙...+1) and (PL4) activate on the basis of the mode
defined by the controls configured A=1 PL=3, A=1 PL=4 and A=1 PL=6. Whether there
are configurators 1 to 4 in position M of the actuator or not makes no difference.
NOTES:
(2) The value of the configurator in the table defines the final time, after which the
actuator deactivates.

Operation
- The opening of the external rabbeting shutter must start before the opening of the
internal rabbeting shutter. The PL1 opening activation time will start 3 seconds after
the start of PL3.
- The closing of the external rabbeting shutter must start later than the closing of the
internal rabbeting shutter. The PL1 closing activation time will start 3 seconds after
the start of PL2.
- During installation it must be possible to adjust the total shutter opening/closing
operation time within a range of 15 to 25 seconds, based on the size of the shutter,
to allow for strong opposite wind.
