Analog 4-20 mA Output (Optional)
An optional single 4-20 mA analog output is available (Figure 3.21). To determine if the analog output is
installed, inspect the board for terminals 39 and 40. If they are not present, the option is not installed.
Figure 3.21—Wiring diagram for analog 4-20 mA output
If the analog 4-20 mA output is not installed, one can be obtained via the addition of an expansion board.

Appendix D: Input/Output Expansion Board , page 103 .
Console Serial Port
The console port is accessed through the 4-pin A01 connector (CN34) located on the underside of the
main board, on the terminal block side. This port is wired to a connector accessed from the bottom of the
enclosure, and is typically used with a console device, such as a PC. As shown in Figure 3.22, the
console serial port connector is protected by a tool-secured cover. By loosening one of two screws, the
operator can pivot the top cover plate to the side for direct access to the connector.
