SECTION 12 – LOGIC AND SIGNAL POWER OPTIONS
Standard Systems Using 24VDC Logic And Signal Power
If the system derives its power from a source that is higher than 24VDC an external
AC/DC or DC/DC power supply unit must be used to convert the incoming supply
voltage into the required 24VDC logic supply.
Logic Supply
The 24VDC logic supply should be connected to the terminals VS and 0VS
on the logic rack. The logic supply is protected with a 5A Fuse (F2) and a monitor LED
is provided to indicate the status of the fuse.
Signal Supply
Standard 9000TS Systems p24VDC as a signal supply voltage which is
derived from the logic supply on the P925TS-X Interface Card.
The 24VDC logic supply oVS and OVS are wired into the signal supply input
terminals VC IN and OVC IN.
The signal supply voltage, (+24VDC), is available on teVC OUT for distribution
to the customers signal input contacts. The signal supply output is protected with a 1A
fuse (F1) and a monitor LED is provided to indicate the status of the fuse.
Please note:- Each P925TS-I Input Card is equipped with a 3 pin header and 2 way
shorting bar that allows selection of inputs suitable for operation from 24VAC/DC or
125VAC/DC. Please ensure the jumper is in the correct position before applying
power.
