The extension cable connects MC200-5AM to the system, while the
extension port connects MC200-5AM to another extension module of the
system. For details on connection, See
1.2 Connecting Into System.
The user port of MC200-5AM is described in Table 1-1.

Note:
An input channel cannot receive both voltage signals and current
signals at the same time. If you intend to use a channel for current
measurement, short its voltage input terminal and current input terminal.
1.2 Connecting Into System
Through the extension cable, you can connect MC200-5AM to MC200 series
basic module or other extension modules. While through the extension port,
you can connect other MC200 series extension modules to MC200-5AM. See
Figure 1-3.

Figure 1-4 Wiring of MC200-5AM user port
The circled 1 ~ 9 stands for the nine points to be observed during wiring.
1. It is recommended to use shielded twisted pair for the analog input and
output and separate them from power cables and any cable that may
generate EMI.
2. If the I/O signal has electric noise or voltage fluctuation, it is advisable to
connect a smoothing capacitor (0.1µF ~ 0.47µF/25V).
3. If strong EMI exists, connect the FG terminal to the PG terminal.
4. Each load of the PLC should be grounded separately
．
5. If a channel is used for current input, short its voltage input terminal and
current input terminal.
6. Shorting the voltage output terminals or connecting current load to voltage
output terminals may damage MC200-5AM.
7. Properly ground the module’s PG terminal.
8. The basic module’s 24Vdc auxiliary power or other qualified external
power supply can be used as the power source of the module’s analog
circuit.
9. Do not use the NC terminal.
