Description
Introduction
With the Schischek InMax-50-F | 50 Nm, quarter-turn actuator, IP67, you choose an industrial InMax actuator with IP67, universal 24…240 VAC/DC power supply, and flexible control. This increases safety and continuity in any space, while also benefiting from easy integration and reliable performance.
Features
- IP67 housing; therefore suitable for demanding environments
- Universal 24…240 VAC/DC power supply
- Among others: 3-point, on/off or modulating 0–10 V / 4–20 mA
- Available with spring return (~3 s or ~20 s) depending on variant
- Ex-safe circuit and tripping (variant-dependent)

FAQ
What does the Ex-safe circuit do?
That means the actuator switches off safely in the event of a fault; this minimizes risks.
Which control do I need?
Compared with on/off, modulating control (0–10 V/4–20 mA) provides more precise regulation.
When should I choose spring return?
In the event of power failure, the valve automatically returns to a safe position; this increases operational reliability.
Will this fit into my system?
Yes, and you can also connect it to common HVAC and process control systems.
