Power Connections
Power connections are made to a two-terminal
connector labeled POWER. The meter will operate
regardless of DC polarity connection. The + and -
symbols are only a suggested wiring convention.
Figure 11: Power Connections
Signal Connections
Signal connections are made to a six-terminal
connector labeled SIGNAL. The COM (common)
terminal is the return for the 4-20 mA and the
10 V
input signals.
Current and Voltage Connections
The following figures show examples of current and
voltage connections.
There are no switches or jumpers to set up for current
and voltage inputs. Setup and programming is
performed through the front panel buttons.

Supply or Self-Powered
The current input is protected against current
overload by a resettable fuse. The display may or
may not show a fault condition depending on the
nature of the overload.
The fuse limits the current to a safe level when it
detects a fault condition, and automatically resets
itself when the fault condition is removed.
Figure 14: 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. For interfacing to
the P
RO
V
U
, use the PDA1232 for RS-232 or the
PDA1485 for RS-485. The same port is used for
interfacing with all expansion modules (
e.g.
external
relays, digital I/O).
Relay Connections
Relay connections are made to two six-terminal
connectors labeled RELAY1
– RELAY4. 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.
