The Ascon Tecnologic vP4 is a state-of-the-art PID controller engineered for applications that demand more than simple temperature regulation. As part of the Vance series, the vP4 excels in complex process control by offering two independent universal analog inputs, allowing for dual-loop control, cascade regulation, or ratio control within a single, compact industrial housing.

Advanced Dual-Loop Control and Math Logic

The vP4’s dual universal inputs are its core strength. These inputs can be used to manage two separate PID loops simultaneously or combined via the controller’s internal math blocks to calculate differential temperatures, RH% (relative humidity), or specialized flow compensations. With 8 integrated logic blocks, users can define custom control strategies that traditionally required a small PLC, effectively reducing system complexity and cost.

Connectivity for Industry 4.0

In modern automated environments, data visibility is paramount. The vP4 offers robust RS-485 serial communication as standard, ensuring compatibility with legacy SCADA systems. For high-speed data exchange and remote monitoring, the optional Ethernet interface supports the Modbus TCP protocol, enabling the controller to be integrated directly into local networks or connected to IIoT gateways for cloud-based data tracking.
