Binary output
The binary output is realized by a transistor with open collector. In inactive state (log. 0)
the transistor 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 transis-
tor collector is power supply voltage of the router.
The impulse length is possible set in range 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
(viz. picture) is mounted on pins, electric current value is 20 mA. When jumper J4 is not
mounted, electric value is 8
μ
A. If current value is 20 mA, CNT has higher consumption,
also it has higher resistance to industrial noise.
