The PDB-0824 power distribution board enables easy distribution of 24Vdc from the main power rail to individual 24Vdc devices inside the cabinet enclosure, such as fan units and FTAs.

Figure 496 on page 792 shows the PDB-0824 board with one 24Vdc entry connector (In) for connection to the main bus bar and eight (2 Amp fused) 24Vdc field connectors (Out1 thru Out8) for connection to eight 24Vdc devices.A 24 Vdc power distribution cable (see data sheet “PDC-MB24-x” on page 812 for details) can be used to connect the main power bar to In.

• When using other connection cables make sure the wire size is adequate and a Weidmuller BVZ 7.62/02F SW connector with two keying pins is used to connect to In of the PDB-0824 (see “Pin allocation” on page 793).

24V distribution cables (see “PDC-FTA24” on page 816) connect the PDB-0824 with up to eight 24Vdc devices.

• When using other connection cables make sure the wire size is adequate and a Weidmuller BL 5.08/2 SN OR or equivalent connector is used to connect to one of the Outx connectors of the PDB-0824 (see “Pin allocation” on page 793).

Pin allocation

Figure 497 on page 793 shows the top, side & bottom view and the pin assignment of the Weidmuller BVZ 7.62/02F SW cable-connector on In.

1. The pin marked “+” is pin 1; connect to +24Vdc wire to the main bus bar

2. The pin marked “-” is pin 2; connect to 0Vdc wire to the main bus bar

The two (orange) locking slides of the cable-connector in Figure 497 on page 793 keep the cable-connector locked when inserted into In.

Figure 498 on page 793 shows the top, side & bottom view and the pin assignment of the Weidmuller BL 5.08/2 SN OR or equivalent connector to an Outx field connector on the PDB-0824.

Power Distribution Board (24Vdc, 2 Amp, 8 channel)

Description

The PDB-0824P power distribution board enables easy distribution of 24Vdc from the main power rail to individual 24Vdc devices inside the cabinet enclosure, such as fan units and FTAs.

Figure 500 on page 796 shows the PDB-0824P board with one 24Vdc entry connector (In) for connection to the main bus bar and eight (2 Amp fused) 24Vdc field connectors (Out1 thru Out8) for connection to eight 24Vdc devices.

• When using other connection cables make sure the wire size is adequate and a Weidmuller BVZ 7.62HP/02F SN connector with two keying pins is used to connect to In of the PDB-0824P (see “Pin allocation” on page 797).

24V distribution cables (see “PDC-FTA24” on page 816) connect the PDB-0824P with up to eight 24Vdc devices.

• When using other connection cables make sure the wire size is adequate and a Weidmuller BLZ 5.08/2F SN SW or equivalent connector (e.g. BL 5.08/2 SN OR) is used to connect to one of the Outx connectors of the PDB-0824P (see “Pin allocation” on page 797).

Figure 501 on page 797 shows the top, side & bottom view and the pin assignment of the Weidmuller BVZ 7.62HP/02F SN cable-connector on In.

1. The pin marked “+” is pin 1; connect to +24Vdc wire to the main bus bar

2. The pin marked “-” is pin 2; connect to 0Vdc wire to the main bus bar

The two (red) locking slides of the cable-connector in Figure 501 on page 797 keep the cable-connector locked when inserted into In.

Figure 502 on page 797 shows the top, side & bottom view and the pin assignment of the Weidmuller BLZ 5.08/2F SN SW.

1. The pin marked “+” is pin 1; connect to +24Vdc wire to the consumer

2. The pin marked “-” is pin 2; connect to 0Vdc wire to the consumer

PDC-MBMB-1 Mains power distribution cable (24Vdc, 48Vdc)

Description

The PDC-MBMB-1 power distribution cable transfers the 24Vdc or 48Vdc from one mains power rail of type FS-MB-0001 to another mains power rail of that type.

Figure 504 on page 800 shows the layout of the PDC-MBMB-1 power distribution cable.

The cable plugs in the mains power rail with a polarized connector that must be locked on the rail using its two screws. To enable this, the plug must be placed on one of the rail positions that has nuts in the rail housing (see Figure 505 on page 801).

High loads

With second rail loads exceeding 30 Amp (up to 100 Amp) it is recommended to use two PDC-MBMB-1 cables to connect the two power rails

• Connect the first cable close to the top of each power rail.

• Connect the second cable close to the bottom of each power rail.
