SCMPB01
16-Position Analog I/O Backpanel,
Non-Multiplexed
Description
The SCMPB01 16-channel backpanel (Figure 1) can accept any of the SCM5B
analog modules in any mixture. It can be mounted on the SCMXRK-002 19-
inch metal rack. The SCMPB01 has 16 non-addressable analog I/O signal
channels which provides each module with it’s own analog bus. The module
output switch is continuously “on” when using this backpanel and all sixteen
module outputs are simultaneously accessible to high-speed data acquisition
(ADC) boards. A set of inter-channel bridge jumpers permits connecting an input
module’s output to an output module’s input, providing two levels of isolation. A
temperature sensor is mounted on each channel to provide cold junction
compensation for thermocouple input modules (See Figure 2 for schematic).
Field connections are terminated with four screw terminals at each module site.
Use system interface cable SCMXCA004-XX for connection to the host system.
