Figure 10: Voltage Input Connections
The meter is capable of accepting any voltage from -10 VDC to +10 VDC.
Modbus RTU Serial Communications
Serial communications connection is made to an RJ45 connector labeled
M-LINK on Figure 6. For interfacing to the
PROPLUS
, use the
YPPA1232 for RS-232, the YPPA1485 for RS-485, or the YPPA8008 for
USB. The same port is used for interfacing with all expansion modules
(
e.g.
external relays, digital I/O).
Use the YPPA1200 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 6. 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.
