PK2100 Inputs and Outputs
The PK2100 provides these types of inputs/outputs:
•
•
•
•
•
•
•
•
“Universal” analog inputs.
Protected digital inputs.
High-gain differential analog input.
SPDT relays.
High-current driver outputs capable of driving inductive loads such as
solenoids and relays.
Analog outputs.
2 × 20-charcter LCD screen (backlighted display available) and 2 × 6
keypad.
Serial communication channels: PLCBus port, RS-232 port, and
RS-232 or RS-485/RS-422 port.
Figure 3-1 shows the signal names of the PK2100’s screw connectors.
The chapter describes the various interfaces and presents some typical
applications. There are 50 screw terminals used for input, output, and
power connections. In addition, there are two connectors on the sides of
the unit: a modular “phone jack” connector for the RS-232 port, and a
26-pin connector for the PLCBus expansion port.
