Note
The Crouzet 32 module backplane has no position on the backplane for either a
fuse or jumper. You must add a power supply fuse elsewhere before connecting the
power. Use a fuse that is suitable for your application.
SSR Module Installation
You can install the SSR modules by plugging each module into one of the
positions on an SSR backplane. They are keyed so they cannot be inserted
incorrectly. Many DAQ devices require that all DIO lines in a port be
configured either for input or output. In these cases make sure you install
the same type of SSR module, input or output, for each line in the port.
You can mix input and output SSR modules on the mounting rack only if
you connect them to different I/O ports or you use a DAQ device that allows
mixed line directions within a port. Do not attach input modules to output
lines under any circumstances or you can damage the SSR modules or the
DAQ device.
LEDs
Each module position of an SSR backplane has a status LED to show the
status of the SSR module logic line. For input modules, the LED is on when
the load voltage is within the specified range of the SSR module. For the
