### Product description – Universal pump control module PQP-176-P
The PQP-176-P module offers a versatile solution for the swivel angle, pressure and power control of variable displacement pumps. It supports the control of directional valves with one or two magnets, including valves with integrated electronics. An internal slide position controller also enables precise control of valves with electrical feedback.
**Functions and features:**
– **Control structures:** Cascade control, suitable for pumps from various manufacturers. Supports swiveling above zero with pressure and power limiting signal from a second pressure transmitter (closed circuit) or active pressure reduction in the open circuit (mooring operation).
– **Communication:** Setpoint specification and control are carried out via Profinet, current process data and status information are reported back.
– **Flexible signal inputs:** Analog signals (0…10V or 4…20mA) freely scalable to adapt to individual requirements.
**Extensions:**
The module can be combined with the LDT-401 module to read additional values such as swivel angle or slide position via the backplane bus.
**Reliability:**
The regulated output currents are independent of the power supply and magnetic resistance. Short circuit and cable break monitoring ensures safety; in the event of errors, the output stages are switched off.
**Easy to use:**
The module impresses with intuitive, problem-oriented operation and a short training period. Parameterization is carried out conveniently via the WPC-300 software or Profinet.
**Typical applications:**
– Swivel angle control
– Pressure and power control
– Master-slave control for several pumps
**Special advantages:**
Universally applicable, ideal as a replacement for OEM cards such as Rexroth VT-VPCD. Optimized control functions and reproducible settings make the PQP-176-P the ideal solution for versatile control tasks.
