Status LEDs for digital inputs
The physical states of the inputs and the diagnostics
status word are indicated by LEDs.
Status LEDs for outputs
The logical states of the outputs are indicated with
light-emitting diodes (LEDs). Outputs Q 0.6 and Q 0.7
are only provided as LEDs.
Digital/analog outputs, analog inputs
Digital outputs:
The PS4-200 has 6 24 V/0.5 A digital outputs. They
are galvanically isolated from the CPU and protected
against short-circuits and overloads. Up to four
outputs can be connected in parallel.
Analog inputs/outputs:
The controller has two analog inputs and one analog
output. The signal range is 0 to 10 V. The resolution
of the inputs is 10 bits (1024 increments), while that
of the output is 12 bits (4096 increments)..
All the inputs and outputs are wired via plug-in screw
terminals.
Outputs Q 0.0 to Q 0.5 can be addressed either
in bit or byte format with peripheral commands
(see chapter 5 “Slave addressing”).
The section “Power supply” in the Engineering
chapter contains a connection diagram of the
analog inputs and outputs.
