Figure 9. Voltage Input Connections
The meter is capable of accepting any voltage from -10 VDC to +10 VDC.
Serial Communications
Serial communications connection is made to an RJ45 connector la-
beled M-LINK on Figure 5. Use PDA1232 for RS-232 interfacing or the
PDA1485 for RS-422/485 interfacing. The same port is used for inter-
facing with all expansion modules (e.g. external relays, digital I/O).
Use the PDA1200 meter copy cable for meter-to-meter interfacing for
cloning purposes (
i.e.
copying settings from one meter to other meters).
Relay Connections
Relay connections are made to two six-terminal connectors labeled
RELAY1 – RELAY4 on Figure 5. Each relay’s C terminal is common
only to the normally open (NO) and normally closed (NC) contacts of the
corresponding relay. The relays’ C terminals should not be confused
with the COM (common) terminal of the INPUT SIGNAL connector.
