The programmable logic valve control of type PLVC 16 consists of a complex PLC-enabled micro-control unit with integrated
amplifiers for mobile and stationary hydraulic applications.
The wide range of possible applications includes, among others:
'
Cranes, crane systems
'
Construction machines
'
Complex hoisting equipment
'
Logging equipment
'
Hydraulic clamping systems for machine tools
'
Presses
The various control tasks are realized through:
'
A modular system with extension and supplementary modules
- Basic module
- Extension module (additional inputs/outputs, receiver for radio control) (optional)
- Text display for diagnosis, and parameterization (via CAN-Bus)
- Large display for diagnosis, and parameterization (via CAN-Bus)
- CAN-Bus controlled power relay
'
Flexible programmability according to IEC 61131-3 standard (PLC-programming via instruction list (IL), function block diagram
(FBD) or structured text (ST))
'
Various interfaces (RS232, CAN-Bus)
'
Free parameterization of all outputs, as well as complete diagnosis capability and short-circuit protection
'
Remote diagnosis via modem or mobile phone
'
Combination of multiple PLVC’s via CAN-Bus within one integrated unit for the control of complex systems
All relevant standards regarding personal safety, EMC, vibration- and shock-proofness are complied with.
The main performance parameters include furthermore:
