ELECTRICAL CONNECTION

Illustration 3 Electrical connections transmitter PMA 05
The electrical connection of the M&C PMA 05 oxygen transmitter is via the 12-pin. plug Item 9
(Figure 3). This is where the transmitter receives power and the measurement signal is transferred.
Terminal 11 + 12: Supply voltage 24V DC (max. 1.5 A) for heating and transmitter
Terminal 9 + 10: Temperature status contact for all versions with heating, in addition, these
versions have a non-reversible thermal fuse 72 °C
Terminal 7 + 8: Signal output 4-20mA (galvanically isolated) for the ordered measuring range e.g.
0-100% O
2
Terminal 5 + 6: Signal output 0 - 10V (galvanically isolated) for 0 - 100% O
Terminal 1 - 4 there are 4 terminal points available for optional features such as a PT100.
