Use of +12V DC & -12V DC - NCR ATM

[mss230479]

Hi Friends,

In NCR ATM we are getting following output voltage from Power supply unit (Main SMPS & Slim line). Which modules uses +12V & -12V DC.
As i know +5V DC for PCB & +24V DC for DC motors.

I found this:
"In the 5670 ATM plug P10 connects into the 5670 I/O Board connector J10. The I/O Board distributes dc power to the boards in
the electronics core of the ATM and has connectors for the +24 supply to the PSU fan and +12 v to the CPU fan (see Chapter 21.5
“5670 I/O Board”).
Also, on the connector to control the motorized shutter interface board.( J1 on 56xx ATM's 10=+12V, 11=-12V)
Connector J4 provides the interface to the currency dispenser pick modules. It is a 40-way right-angle latched header connector:
(on dispenser board 30 =+12V= 11 on pick interface board)
At MCRW: Dual 4-way connector J11 provides three power lines (+24V, +12V, +5V)and associated return Grounds.
