Voltage supply
In the connector unit MA 2, the connections for the voltage supply are implemented twice.
This permits wiring through or the voltage supply of additional components.
Table 6.4: Terminal assignment voltage supply
Notice!
It is imperative that the protective conductor PE also is wired through to avoid electromag-
netic interference.
Switching inputs 1 and 2
The MA 2 connector unit is equipped with two switching inputs SE 1 and SE 2 (SE 2 can
only be activated with BCL 22).
• Input voltage: 12 … 30VDC
Table 6.5: Terminal assignment switching inputs
Switching outputs 1 and 2
The MA 2 is equipped with 2 switching outputs SA1 and SA2 (SA 2 can only be activated
with BCL 22) which can be programmed for various switching functions using the
"BCLConfig" software.
• Output voltage corresponds to operating voltage
• Output current: I
max
= 100mA
The switching voltage for the output is generated by the operating voltage V_IN:
• VDD_SA = VDD_IN
• GND_SA = GND_IN
