Basic Parameters
Input Signals: The positioner accepts a wide range of standard input signals, including 4-20 mA DC current signals and optional 0-10 V DC voltage signals. This flexibility allows seamless integration with various control systems, such as distributed control systems , programmable logic controllers (PLC), and single-loop controllers. The input impedance for 4-20 mA signals is typically 250 ohms, ensuring compatibility with standard signal sources without the need for additional signal conditioning.
Output Signals: To actuate control valves, the V18348-101 provides a pneumatic output signal, available in two configurations: 0.2-1.0 bar and 0.4-2.0 bar . This dual-range capability enables the positioner to work with both single-acting and double-acting actuators, making it suitable for a broad spectrum of valve types, including globe valves, butterfly valves, ball valves, and plug valves. The output air capacity is rated at up to 100 Nl/min at 6 bar supply pressure, ensuring fast response times even for large actuators with high air consumption.

The output air capacity is rated at up to 100 Nl/min at 6 bar supply pressure, ensuring fast response times even for large actuators with high air consumption.
Materials of Construction
Housing: The outer housing is constructed from glass-reinforced polyamide (GRP), a material known for its high strength-to-weight ratio, excellent impact resistance, and resistance to UV radiation, chemicals, and extreme temperatures. The GRP housing provides robust protection for internal components while remaining lightweight and easy to handle during installation and maintenance.
Internal Components: Critical internal components, such as the feedback mechanism, linkage, and valve seats, are made from corrosion-resistant materials including stainless steel (AISI 316L) and anodized aluminum. These materials ensure long-term reliability in corrosive environments, preventing rust and degradation that could affect performance over time.
Seals and Gaskets: High-performance elastomeric seals and gaskets, made from materials such as nitrile rubber (NBR), fluorocarbon rubber (FKM), and ethylene propylene diene monomer (EPDM), are used to ensure airtight sealing and protection against moisture and chemical ingress. The selection of seal materials is tailored to the operating environment, with FKM seals recommended for high-temperature and chemical-resistant applications.

Digital Signal Processing
For enhanced precision and flexibility, the ABBe V18348-101 features a built-in digital signal processor that processes both the input setpoint signal and the feedback signal. The DSP provides several key benefits, including improved accuracy, advanced diagnostic capabilities, and the ability to implement complex control algorithms.
The DSP converts the analog input and feedback signals into digital data, which is processed using advanced control algorithms such as proportional-integral-derivative control. The PID algorithm calculates the optimal pneumatic output based on the proportional (P), integral (I), and derivative (D) terms, ensuring fast response to setpoint changes, elimination of steady-state error, and damping of oscillations. The PID parameters can be adjusted via the positioner's local interface or through a digital communication protocol, allowing for fine-tuning to match the specific characteristics of the valve and actuator.
