IC200ALG240
Analog Input Module, 16 Bit Voltage/Current, 1500 V AC Isolation, 8 Channels
Cable Shield Connections
If possible, analog input channel connections should be grounded at the source
device. If that is not possible, the cable shield must be grounded at the I/O
module.
If the module is installed on a Terminal-style I/O Carrier (IC200CHS001, 002, or
005) or a Compact Terminal-style I/O Carrier (IC200CHS022 or 025), the cable
shield can be connected directly to the carrier per the Field Wiring Table. An
Auxiliary I/O Terminal Strip (IC200TBM001, 002, or 005) can also be added to
the Terminal-style I/O Carriers to aid in grounding shields. If the module is
installed on a Compact Terminal-style I/O Carrier (IC200CHS022, 025), shield
connections can be made on an Auxiliary I/O Terminal that is mounted near the
I/O carrier. Be sure to ground the Auxiliary I/O Terminal Strip as well to use it
for this purpose.
If the module is installed on a Connector-style I/O Carrier (IC200CHS003), the
cable shield can be connected directly to an Interposing Terminal
(IC200CHS011, 012, 015). Be sure to ground the Interposing Terminal. It is
recommended to use a shielded interposing cable as well between the
Interposing Terminal and the Connector Base. A custom shielded cable can be
made using the Connector kit (IC200ACC304). In addition, a custom shield
braid can be wrapped around standard Interposing Cables (IC200CBL105, 110,
120, 230). If this approach is used be sure to ground the braid.
Operation
The default parameters of this module can be used in many applications. The
module can be software-configured when it is installed in a VersaMax PLC
system, or an I/O Station controlled by a Network Interface Unit that is version
2.0 or above. The module is configured at startup. If the module is auto-
configured, it will operate with its default features. After configuration, the
module begins receiving signals from the input devices connected to it.
Calibration
The module is calibrated at the factory. For most applications, no further
calibration is required. It is possible to perform recalibration by changing a
module's scaling so its scaled data agrees with metered values.
