Schubert & Salzer – Type 2040 – Digital Position Indicator

Overview

The Schubert & Salzer Type 2040 is a compact optical and electronic position indicator designed for direct mounting on pneumatic valves equipped with linear or part-turn actuators. It provides both a visual display of valve position and electronic position feedback via NPN switching contacts, making it suitable for integration into automated process control systems.

The Type 2040 features a self-teaching adaptation mode for quick calibration to the actuator stroke, and supports full configuration and diagnostics through the Schubert & Salzer “DeviceConfig” PC software (version 7.02.00 or higher). The unit also monitors for valve faults and configurable maintenance intervals, outputting alerts both visually and through a dedicated NPN switching output.

Features & Benefits

• Compact aluminum housing with polycarbonate dome — suitable for direct mounting on valve actuator without additional brackets in most configurations
• Visual display of valve position (open/closed) — provides at-a-glance status in the field
• Three NPN switching outputs (UP, DOWN, ERROR) — enables direct PLC or relay integration without additional signal conditioning
• Error detection and output — detects valve sticking and similar faults; signals via red indicator lamp and dedicated NPN switch contact
• Configurable maintenance interval tracking — triggers a pulsating 1 Hz signal on the error output when a scheduled maintenance interval is reached
• Self-teaching semi-automatic stroke calibration — simplifies commissioning by automatically adapting to actuator travel
• Fully configurable via “DeviceConfig” PC software — all operating parameters, output polarity, and maintenance intervals adjustable through software
• IP65 protection rating — suitable for installation in wet or dusty industrial environments
