3.4 Power Supply Options
TPPR can be supplied from an AC 110/240 V Single Phase industrial supply via the optional Power Supply (PSU) Modules,
or from a direct DC 24 V power supply, or from optional 24 VDC backup batteries via the DC Uninterrupted Power Supply
module (DC-UPS).
When specifying power supplies, you should consider cabinet internal temperatures and cooling. In addition, power supplies
should be rated to allow for current surges and peaks. Contact your Honeywell representative for advice.

A full description of the available module types is given in the following sections.
3.4.1 Power Supply Unit Modules (PSU)
The TPPR System can be equipped with PSU modules of different capacity, depending on the number of I/O modules being
used. The power supplies are mounted to the DIN-Rail and are available in the following ratings:
120/180 W, 24 – 28 VDC (5 A @ DC 24 V)
240/360 W, 24 – 28 VDC (10 A @ DC 24 V)
480/720 W, 24 – 28 VDC (20 A @ DC 24 V)
The power supplies have a 'DC Ok' status output that can be used to give a fault warning on failure.
