LED Power, channel 1, channel 2 and fault
Devices has two voltages : 1 voltage fixed : 24 V DC;
OPERATING VOLTAGE Selectable : 24, 110-127 and 230 V AC
(with galvanic disconnection/transformer)
POWER CONSUMPTION ca. 3 VA
START UP DELAY / FALLBACK TIME <150 ms/< 50 ms (undelayed)
CONTACT CAPACITY max. 6 A, 250 V AC, 24 V DC
CONTACT CAPACITY min. at 24V DC (*) 100 mA (*)
SIMULTANEITY Simultaneous protective door contacts : ca.75 ms
ENVIRONMENTAL TEMPERATURE - 25°C to + 50°C
SWITCHING CAPACITY 1500 VA (resistive load)

OPERATING MODE
(*) We offer all devices who have a CONTACT
CAPACITY of min. 100 mA at 24 V DC with
hard gold-plated contacts. In this way the
CONTACT CAPACITY of min. 100 mA is only 4 mA.

CONNECTION DIAGRAM
A supply voltage must be applied to terminals A1 and A2 (for AC supplies)
or terminals B1 and B2 (for DC supplies). Once the supply voltage is
applied, 24V DC is available at terminal T11; power LED illuminates.
Terminals T12, K21 and K22 must be connected according to the
application example selected to meet the application requirements.
Feedback monitoring of external devices is accomplished by a connection
between terminals T34 / X1 and X2. If the application does not require
external monitoring, T34 / X1 and X2 must be bridged. To start the unit,
terminal T11 and T34 / X1 must be bridged (automatic reset) or a
momentary bridging of T11 and T34 / X1 must take place. With all of the
above in place safety contacts 13-14, 23-24 and 77-78 close. Channel 1 (K2
energized) and channel 2 (K3 energized) green LEDs illuminate to show
channel status. Fault LED illuminates when a short circuit takes place, at the
input stage or internally.
(*) Special edition with hard gold-plated contacts is also available.
Connecting the ground wire to PE - see page 22.
