Description

The PSX-D8 and PSX-D8P simple distribution accessory

provides eight zones of fused (PSX-D8) or PTC-protected

(PSX-D8P) distribution with no built-in control features. The

PSX-D8/D8P accepts one or two power inputs, which can be

powered either by the DC1 and DC2 outputs of a single PSX

power supply or by the DC1 outputs of two separate supplies.

Each output zone of the PSX-D8/D8P is selectable for either

input source.

Mounting the PSX-D8/D8P Power Distribution Module

Mounting of the board to an enclosure is via the four

snap-in standoffs supplied.

1. Locate the appropriate

mounting holes in the

enclosure and snap

the standoffs into the

holes.

2. Align the board mount-

ing holes with the

standoffs (be sure the PC board is properly oriented)

and snap the board onto the standoffs.

FlexIO Connectors

These connectors pass the FlexIO buss through the

PSX-D8/D8P to other accessory boards in the system.

2

B1 Connectors (J1 & J4)

These fastons are for connection to the B1 voltage buss

in the system. The voltage on the B1 buss comes from

the DC1 faston of a PSX power supply. This voltage

will be directed to any outputs whose Output Selection

Jumper is set in the B1 position.

3

B2 Connectors (J3 & J5)

These fastons are for connection to the B2 voltage buss

in the system. The voltage on the B2 buss comes from

the DC1 faston of a PSX power supply in a dual voltage

system. This voltage will be directed to any outputs whose

Output Selection Jumper is set in the B2 position.

If the PSX-D8/D8P is being used in a single voltage sys-

tem, these fastons can either be left unused or connected

to the PSX Power Supply’s DC2 output, to provide FAI con-

trol to outputs selected for B2.

4

BR Connectors (J2 & J6)

The DC Common buss in the system. All boards in the

system must have their BR fastons wired together for

proper operation.

5

Output Selection Jumpers (JP1 – JP8)

These jumpers select which voltage buss input is select-

ed for the output. Jumper numbers correspond with the

zone number (e.g. JP1 is the jumper for OUT1). Possible

settings are as follows:

• Position 2 (Left) – B2 Buss

• Position 1 (Right) – B1 Buss

• Removed – Disable Output

6

Output Fuses (F1 – F8) – Optional

When using the fused version of the board, these are

the fuses for each zone output. Fuse numbers corre-

spond with the zone number (e.g. F1 is the fuse for OUT1).

When using the PTC version of the board, the fuse will

be replaced with a soldered-in PTC.

7

Zone Outputs (Out1 – Out8)

These are the zone output terminal strips. These ter-

minal strips are removable and accept wire sizes from

AWG14 – AWG22. The terminals are labeled on the PC

board underneath the terminal strip.

CAUTION When powering magnetic loads such as

maglocks, door strikes, solenoids, etc, each of these

loads must have a reverse protection diode either built-in

or external to the device.

8

Output LEDs (D1 – D8) – Green

These LEDs indicate the availability of voltage on a

zone’s output. When voltage is available on the output

terminals, the LED is lit. LED numbers correspond with

the zone number (e.g. D1 is the LED for OUT1).

Connections to the module shall be

completed within the same room,

not exceeding a length of 100 ft.

Class 2 power limited wiring must be

seperated from non-power limited wiring

by a minimum of 1/4 inch and must use

seperate knockouts

• The installation and all wiring methods

shall be in accordance with ANSI/NFPA70

and all local codes.

For ULC compliance, installation and all

wiring methods shall be in accordance

with the Canadian Electrical Code, C22.1,

Part I, Section 32

PSX-D8 and PSX-D8P INSTALLATION MANUAL 3

PSX-D8, D8P – Application Examples

This application shows PSX-D8/D8P usage in a single-supply system when FAI is not required.

• The B1 input is connected to the DC1 output of a PSX power supply or the DCOUT of a PSX-B100 secondary power sup-

ply. B2 is left disconnected.

• The jumper for each zone is set for B1 (Position 1) and in this application, all zones output a continuous 24VDC.

This application shows PSX-D8/D8P usage in a single-supply system using FAI.

• The B1 input is connected to the DC1 output of a PSX power supply. B2 is connected to the DC2 output of the Power Supply.

• In this application, any zone output with its jumper set in Position 1 will have a continuous 24VDC output.

• Also, any zone output with its jumper set in Position 2 will change states when the Power Supply receives a valid FAI input

signal. The outputs can be set to enable on FAI or disable on FAI by setting the position of the Power Supply’s DC2 fuse

(See PSX Power Supply manual for more information). The voltage on these outputs (when active) will also be 24VDC.
