Digital outputs 
There are four digital outputs (electrically isolated passive output circuits) in the connection box 
(TB6-terminals, details see figure 5.6). 
The  output  at  TB6-5  is  a  breaker  (NC,  “normally  closed”),  the  other  outputs  are  makers  (NO, 
“normally open”). The maximum load per channel is 28.8 V DC/120 mA. The maximum pulse rate is 
25 Hz. 
Cable type refer to  5.4.2 Cables (power supply / communication) the maximum length is 250m ≙ 
820ft.  The  figure  also shows the  appropriate  terminals in the  connection  box.  The  wiring  in the 
drawing is only designed to illustrate the screening using an example.
