1.4. Block diagram

Parker electronic modules PID00A-40* for rail
mounting are compact, easy to install and provide
time-saving wiring by disconnectable terminals.
The digital design of the circuit results in good ac-
curacy and optimal adaption for closed loop con-
trols by a comfortable interface program.
The described electronic unit combines all neces-
sary functions for the optimal operation of closed
loop controls. The most important features are:

1.5. Characteristics

•  Extended PID controls
•  Velocity control with position feedback
•  Differential input stage with different signal op-

tions

•  Output stage with different output options
•  Four-quadrant ramp function
•  Status indicator
•  Digital circuit design
•  Parametering by serial interface RS-232C
•  Connection by disconnectable terminals

• Compatible to the relevant European EMC

standards

• Optional technology function "linearization"
• Comfortable interface program. Download free
