Trusted High Integrity Power Supply System 1. Description
Rockwell Automation Publication PD_T8200 Issue 11 3
1. Description
The Power Supply Assembly consists of a Power Supply Chassis containing up to six Power
Supply Modules. The Chassis may be configured to distribute power in various
combinations. For example, a Chassis containing six Power Supply Modules may be set up
with three Modules providing triplicated power for Regent+Plus Input/Output (I/O)
assemblies and three Modules providing field power in a N+1 configuration. Alternatively,
the Chassis may be set up to provide separate dual 24 Vdc supplies for both a Trusted
System and associated field devices.
Figure 1 Power Supply Assembly
1.1. Power Supply Chassis
The Power Supply Chassis houses a maximum of six Power Supply Modules. It may be
mounted in a 19-inch rack or flush mounted on a panel. Table 1 identifies the available types
of Chassis.

1.2. Power Supply Modules
The Power Supply Assembly Modules are single (if redundant inputs are not required) and
dual input, hot swap, user-replaceable ac and dc units. Table 2 identifies the available types
of Modules.

The dual inputs on the ac Modules are galvanically isolated from each other. The inputs on
the dc Modules are diode isolated and share a common return.

Rockwell Automation Publication PD_T8200 Issue 11 5
Figure 3 Block Diagram of a Dual dc I/O Power Supply Module
Each primary power input is individually fused and filtered with both standard line filters
and metal oxide varistors (MOVs). The filters attenuate any high frequency common mode
and normal mode noise present in the power distribution system. The MOVs clamp high
voltage transients.
Filter, rectifier, and power factor correction circuits convert primary ac input power to bulk
dc voltage. The switching regulator converts bulk dc power to regulated dc output voltage.
Sensing, status, control and timing circuits provide for the following:
•Input power failure - Active low status output. Indicates when the input voltage is
below 85 Vac or 18 Vdc. There is a separate signal for each input.
•Bulk power failure - Active high status output on ac input modules only. Indicates
the dc bulk voltage (power factor correction (PFC output)) is outside the specified
range. There is a separate signal for each input.
•High temperature warning alarm - Both an active high and active low status output
are provided. Indicates when the module temperature exceeds 75 °C. The
temperature is sensed near the air inlet (bottom) of the module.
•High temperature shutdown - Internal signal that will shut down the switching
regulator if module temperature is above 85 °C. The temperature is sensed near the
air inlet (bottom) of the module.
•Output over-voltage - Internal signal that will shut down the switching regulator if
the output voltage exceeds +18 Vdc for the 15 volt module and +28 Vdc for the
24 volt module. Over-voltage protection circuitry activation is a permanent error
condition, requiring manual intervention to return module to normal operation.

•dc output fail - Active high status output indicates the dc output voltage has gone
out of regulation. The dc output fail threshold is 13.75 Vdc (±0.25 Vdc) for the 15 volt
module, and 21.75 Vdc (±0.25 Vdc) for the 24 volt module.
•Output current limiting - Internal signal limits output current in excessive current
demand situations.
•POWER FAIL - Active high status signal that indicates impending loss of output power
due to one of the following:
oBoth inputs have indicated power failure.
oRemote off control signal activated.
oThermal shutdown.
oOutput over-voltage.
•RESET - Active high status signal that is generated a minimum of 10 ms (ac input
module) or 0.5 ms (dc input module) after a POWER FAIL signal. RESET remains
asserted for 200 ms (minimum) after module power-up.
•PFC off - Active low input that turns off the power factor correction of an individual
input. This signal provides the capability to test the input circuitry of a module by
turning off each input independently while monitoring the module fail signal.
•Remote off - Active low input that turns off the output power of a module.
Note: Bulk Power Fail, PFC Off and Remote Off are accessed through the Monitor Module Connector on the
chassis backplane. The Monitor Module Connector allows for a future development of a monitor card that
would provide remote control and enhanced monitoring of the Power Supply Chassis.
Active low signals are not maintained while RESET is active. All status signals are open
collector and require external pull-up resistors.
RESET is used in the Regent I/O Transceivers for power system interlocking within the I/O
system. A power failure (either input power or module fault) activates RESET and turns off
the dc output Front Panel Indicator.
The POWER FAIL and RESET signals are required for proper operation of Regent I/O
Transceivers and I/O modules during power-up, power down, and loss of power. Refer to
Assembly Installation in the associated Regent Product Description for details of connecting
these signals to a Regent I/O Chassis.

1.4. Front Panel Indicators
The Front Panel of each I/O Power Supply Module supports three Light Emitting Diode (LED)
indicators detailed in the following sub-paragraphs
1.4.1. Input Power Voltage Indicator
Each green INPUT POWER indicator is lit when the associated input (Input A, Input B) is
above the lower input voltage threshold.
1.4.2. Output Power Display
The 10-segment LED indicator bar displays the approximate output current level percentage
(0 % - 100 %)
1.4.3. Output Power Indicator
The DC Output indicator is lit when the I/O Power Supply Module's dc output is within
tolerance. Out-of-tolerance conditions, loss of input power or brown-out, and module
failures turn off this indicator.

Mounting flanges can be attached to either the rear or the front of the Chassis. This allows
flush mounting the Chassis to a panel or mounting in a 19-inch rack.
The Input Crossover Patch is on the T8200 chassis only.

source 1 and source 2 are connected to input A and
input B respectively for all modules slots.

2.2. Backplane Versions and Module Keying
Connector placement on ac Input Modules and backplanes differ from dc modules and
backplanes. This prohibits insertion of the wrong Input Module type into a backplane.
Module slots in a chassis can be individually keyed to only accept a Module of a particular
output voltage.
