8049-4 8049-2 Schubert & Salzer 4-20mA 24VDC 6bar Digital Positioner

Description

Schubert & Salzer 8049-4 3-28 mm stroke, 24 VDC supply, 4-20 mA input, and 6 bar maximum pressure digital positioner. The device features an IP 65 rated anodized aluminum housing with a polymer cover and utilizes a non-contacting stroke sensor for feedback. It is designed for mounting on linear and quarter-turn pneumatic actuators with a standardized G 1/8″ or NPT 1/8″ pneumatic connection. The internal microprocessor-controlled system provides self-adaptation and diagnostic functions via DeviceConfig software while maintaining a stationary air consumption of less than 0.06 Nl/min.
