OM5-BP-8-C 8 POSITION ANALOG I/O BACKPANEL, NON-MULTIPLEXED

DESCRIPTION

The OM5-BP-8-C analog module mounting board has a capacity of eight analog input and/or output modules in any combination. It can be mounted on the OMX-1363-C 19-inch metal rack. A separate analog signal path is provided for each channel and each channel’s signal is accessible at redundant 26-pin connectors. The module output switch is continuously “on” when using this backpanel and all eight module outputs are simulta- neously accessible to high-speed data acquistion (ADC) boards.

A temperature sensor is mounted on each channel to provide cold junction compensation for thermocouple input modules (See Figure 14 for Schematic-

On-board jumpers permit paralleling two OM5-BP-8-C boards to form a OM5-BP-16-C equivalent. An additional set of inter-channel bridge jumpers permits connecting an input module’s output to an output module’s input, providing two levels of isolation (Figures 13, 14).

Jumpers on the OM5-BP-8-C permit user selection of low (i.e. channels 0- 7) or high (i.e. channels 8-15) addresses.

ADDRESS SELECTION

Module addresses may be selected as low (channels 0-7) or high (channels 8-15) using the sets of 3 pins labeled J5 through J12. Place a jumper over the two pins closest to the ribbon cable connectors, P1 and P2, to select a low address (factory configuration) or over the two pins furthest from the ribbon cable connectors, P1 and P2, to select a high address.

ADJACENT CHANNEL JUMPERS

Adjacent channels may be connected together to provide an isolated output signal from an isolated input module, providing two levels of 1500V isolation. This capability is provided with the seven jumpers labeled JP1– JP7.
