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.
Terminals T12 and T22 must be wired as shown in the application
examples. To start the unit terminal T11 must be bridged with terminal T34
by means of a closing contact or terminal T34 must receive a 24V DC
impulse (short time bridging of the connection terminals T11-T34). If this is
down contacts 13-14 and 23-24 close. The LEDs channel 1 and channel 2
illuminate. In series with the start button and terminals T11 / T34 the
function of an external contactor can be monitored.
(*) We offer all devices which have a contact capacity of min. 100mA at 24V
DC with hard gold-plated contacts. In this way you get a contact capacity of
4mA.
