I/O Power Supply Assembly (T8060,T8062)

Structure

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 I/O assemblies and three modules providing field power in a N+1 configuration.

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.

Power Supply Modules

The power su

pply 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.

Input Power Regulation

A block diagram of a typical dual AC input I/O power supply module is shown in Figure 2. A block diagram of a typical dual DC input I/O power supply module is shown in Figure 3.

I/O Power Supply Assembly (T8060,T8062)

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 (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 the module temperature exceeds 75°C. The temperature is sensed near the air inle the module.

High-temperature shutdown - Internal signal that will shut down the

t (bottom) of

switching regulator if module temperature is above 85 °C. The temperature is sensed near the air inlet (bottom) of the module.

Output overvoltage - Internal signal that will shut down the switching

regulatorif the output voltage exceeds +18 VDC or +28 VDC for 15 volt and 24 volt modules respectively. Over-voltage protection circuitry activation is a permanent error condition, requiri to return module to normal operation.

DC output fail - Active high status output indicates the DC output

ng manual intervention

voltage has gone out of regulation. The DC output fail threshold is

13.75 VDC and 21.75 VDC (±0.25 VDC) for the 15 and 24 volt module respectively.

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

Both inputs have indicated power failure

Remote off control signal activated

Thermal shutdown

Output overvoltage

RESET - Active high status signal that is generated a minimum of 10

of the following:

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 monitoring the module fail signal

of a module by turning off each input independently while

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 act signals are open collector and require external pull-up resistors.

ive. All status

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 connect these signals to a Regent I/O chassis.
