Class 1, Div. 2, Standard RTU features a standard 24Vdc power supply with optional 110/220Vac or 480Vac 3Ph configurations. This electro-hydraulic system is designed for double acting operations and can be utilized in both on/off or modulating applications. Additionally, it has the capability to convert double acting to fail safe through an onboard battery system. With onboard calibration for 4-20mA input and feedback, as well as accuracy calculation, the D2 control systems do not require loop power as they are internally powered. In most cases, our hydraulic actuators achieve modulating accuracy of .1% of full scale, making the Volta D2 ideal for low frequency modulating operations.

Standard Features

Self-Diagnostics

Continuous Hydraulic Pressure Monitoring

Continuous Hydraulic Pressure Monitoring

Continuous monitoring and recording of numerous parameters, including valve position, hydraulic actuator pressure, and battery voltage, is essential for effective control systems. Utilizing partial stroke testing ensures reliability within electro-hydraulic systems. The design allows the operator to read all inputs locally on the system, as well as remotely via Modbus protocol.

Continuous Hydraulic Pressure Monitoring

Continuous Hydraulic Pressure Monitoring

Continuous Hydraulic Pressure Monitoring

Monitoring of the actuator pressure in control systems, particularly within electro-hydraulic systems, allows the system to adjust for pressure decreases caused by temperature swings. This mechanism automatically increases the pressure, effectively eliminating what is known as 'valve creep' or false trips associated with hydraulic actuators.

Pipeline Pressure Monitoring

Continuous Hydraulic Pressure Monitoring

Pipeline Pressure Monitoring

The ESD Control System features 2 additional 4-20mA or 1-5V inputs, plus 8 digital inputs designed for monitoring line pressure and integrating various sensors. This includes inputs for limit switches, pressure transducers, temperature transmitters, or level sensors, making it ideal for electro-hydraulic systems and hydraulic actuators. An addon expansion module is also available.

Data Acquistion
