Power Connections
Power connections are made to a two-terminal
connector labeled POWER. The controller will operate
regardless of DC polarity connection. The + and -
symbols are only a suggested wiring convention. There
are separate models for low voltage and high voltage
power. See
details.
Figure 14. Power Connections
Pulse Signal Connections
Signal connections are made to a six-terminal
connector labeled SIGNAL. The COM (common)
terminal is the return for the input signals.
The following figures show examples of signal
connections.
Setup and programming is performed through the
front panel buttons.

Modbus RTU Serial
Communications
Serial communications connection is made to an RJ45
connector labeled M-LINK on Figure 7. Use the
PDA1232 for RS-232 interfacing, or the PDA1485 for
RS-485 interfacing. 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 on Figure 7.
Each relay’s C terminal is common only to the
normally open (NO) and normally closed (NC)
contacts of the cor
responding relay. The relays’ C
terminals should not be confused with the COM
(common) terminal of the INPUT SIGNAL connector.
