To unpack the Unit, open the shipping carton and slide out the corrugated insert
containing the Unit. Remove the Unit from the insert, making sure to retain the
installation slip which accompanies the Unit. Be sure to keep the shipping carton
and corrugated insert, in the event it should become necessary to return the Unit
for service.
The components on the C500-AD501 Analog Input Unit can be damaged by
static electricity. Static control precautions should be observed when unpacking
and handling the Unit during installation and setup.
Before setting the Unit input ranges and installing the Unit to the Backplane,
make sure to review the application requirements, voltage or current modes,
and input cable configuration. Analog signal cables generally have two signal
wires which are labeled plus (+) and minus (–). They may also have an optional
common wire and/or shield wire. Use the configuration worksheet in Appendix A
to record Unit settings.
The Unit uses 5 volt power from the PC power supply. The maximum current
consumption is 1.2 amps. Refer to the Installation Guide for your PC to deter-
mine total system power requirements.
The Unit uses the I/O READ and I/O WRITE ladder instructions to communicate
with the CPU Unit. Each Unit occupies two I/O words in the I/O table. The Units
may be located on the following racks.
• CPU Rack
• CV-series CPU Expansion Rack
• Local Expansion Rack
• SYSMAC BUS/2 Slave Rack
The Unit cannot be mounted to a SYSMAC BUS Slave Rack.
There are normally no restrictions to the number of Units that can be mounted to
the Racks as long as the power supply capacity is not exceeded. Refer to page
78 for special restrictions on SYSMAC BUS/2 Slave Racks.
The C500–AD501 Analog Input Unit has six input signal ranges. The input signal
range is set for each input by setting a DIP switch. The input signal ranges and
DIP switch settings are listed below. Set the voltage/current input selection at the
same time using the slide switch.
