Single Channel DIN Rail Mount Carrier
Description
The 8BP01 is offered as a 5VDC powered (8BP01-X05) or 7VDC to 34VDC
(8BP01-X24) powered single channel DIN rail mount carrier suitable for any 8B
signal conditioner. The 8B carrier can be mounted on any standard DIN rail

2-, 4-, 8-, and 16-Position Analog I/O Backpanels
Description
The 8BP02, 04, 08, and 16 backpanels can accept any of the 8B analog I/O
modules in any mixture and can be mounted on the SCMXRK-002 19-inch metal
rack. Analog I/O signal channels provide each module with its own analog bus.
All module outputs are simultaneously accessible to high-speed data acquisition (ADC) boards. A temperature sensor is mounted on each channel to provide
cold junction compensation for thermocouple input modules (see Figure 6 for
schematic). Field connections are terminated with four screw terminals at each
module site. Use system interface cable SCMXCA006-XX for connection to the
host system.

Electrical
Power
The 8B backpanels have two power supply options. A +5VDC ±5% supply can
be connected to the ‘+5V Supply’ terminal block, or alternatively, a wide ranging
7-34VDC supply can be connected to the ‘Alternate Supply’ terminal block. In
the latter case, the 8BPWR-2 module must be installed on the backpanel. The
backpanel contains circuitry which automatically switches between the supplies
such that only one at a time provides power to the modules. When power
connections are made to both terminal blocks simultaneously, the 7-34VDC
supply takes precedence over the +5VDC supply.
Fusing
Backpanel power is fuse-protected through F1 and F2. Zener diodes D3 and D4
provide extra protection from overvoltage and supply reversal.
Grounding
For full protection against large electrical disturbances on the field-side of the 8B
modules, a #10-32 ground stud is provided on the backpanel. An electrical
connection between this ground stud and the system ground should be provided
with a large gage wire of the shortest possible length.
