Binary output
The binary output is realized by a transistor with open collector. In inactive state (log. 0) the transis-
tor no transfer and is as switch off. In active state (log. 1) is transistor switch on and connect signal
on ground (GND).
Maximal switching current on output is 100 mA. Maximal voltage which can be on transistor collec-
tor is power supply voltage of the router.
The impulse length is possible to set in a range of 125 ÷ 8000 ms which is possible to send on output
after impulses number setting (1 ÷ 65535) on input BIN1/CNT1.
In sleep mode the all input and output values are metered and controlled.

Selecting the current of binary output
If active level is set as log. 1, electric current can be selected with jumper. When jumper J4 (see fig-
ure) is mounted on pins, electric current value is 20 mA. When jumper J4 is not mounted, electric
value is 8
μA. If current value is 20
mA, CNT has higher consumption, also it has higher resistance to
industrial noise.
