24 V AC / DC (without galvanic disconnection, but with a safety
POWER CONSUMPTION 24 V DC: 2W, 24 V AC / DC: 4,5 VA, other: 4,6 VA
START UP DELAY / FALLBACK TIME < 150 ms / < 30 ms
CONTACT CAPACITY max. 6 A, 250 V AC, 250 V DC
CONTACT CAPACITY min. at 24V DC (*) 10 mA
SIMULTANEITY
ENVIRONMENTAL TEMPERATURE - 25°C to + 55°C
SWITCHING CAPACITY 1500 VA (resistive load), 100 W
CONTACT SECURITY 6 A quick acting (normally open) or 4 A time lag (normally closed)
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 at terminals A1 and A2 in order to operate
the device. If this is done there is a voltage of 24V DC at terminal T11. T12
and T22 must be wired as shown in the application examples. Contacts 13-
14, 23-24 and 63-64 open and contact 41-42 closes. In some cases, the
transmitter from the light curtains / barrier requires a test input and is
connected to output 63-64. If 63-64 does not close, the transmitter and the
receiver will not work. This output ensures that a complete system is
created. To start the unit terminal T11 must be bridged with terminal T34
through a normally open contact (reset) or the terminal T34 must receive a
24V DC impulse (short time bridging of the connection terminals T11-T34).
If the light curtains is aligned properly and the protection zone is free, the
receiver switches. At terminal T12 there is a of voltage 24V DC and at T22
is ground. After releasing the on button or interrupting the connection
between T11 and T34 the relays K1 and K4 deenergize. Safety outputs 13-
14 and 23-24 close. Contacts 53-54 and 63-64 remain closed, contacts 41-
42 open.
