Switching outputs
1 and 2
The MA 30/31 normally has 2 switching outputs. These are active as soon as
a scanner is operated on the
MA 30
. They can be programmed for various
switching functions.
On the
MA 31
these switching functions are
not
available!
The switching voltage can be connected in two different ways:
Notice!
The connection between solder bridges JL5 and JL6 must be carefully
scratched through so that there is no longer an electrical connection at this
point. The switching output is then
galvanically decoupled from the oper-
ating voltage
.
The solder bridges are on the MA 30 circuit board directly opposite the con-
nection terminals VDD_SA and GND_SA.

Output voltage:
0 … 48VDC
Insulation voltage:
500V (only in combination with connection type
b)
Output current:
I
max
= 500mA (with VDD_SA = 0 … 32V)
I
max
= 300mA (with VDD_SA = 32 … 48V)
a) The operating voltage V_IN is used as switching voltage VDD_SA
(factory setting):
VDD_SA = V_IN
GND_SA = GND_IN
b) An external voltage is connected as the switching voltage
(galvanically decoupled)
