Description
Introduction
With the Schischek InMax-15-CYF spring-return actuator IP67, you choose an industrial InMax actuator with IP67, universal power supply 24…240 VAC/DC, and flexible control. This increases safety and continuity in every space, while also benefiting from easy integration and reliable performance.
Features
- IP67 enclosure; therefore suitable for demanding environments
- Universal power supply 24…240 VAC/DC
- Including 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 safety circuit and tripping (variant-dependent)

FAQ
What does the Ex safety circuit do?
This means the actuator safely switches off in the event of faults; thereby minimizing risk.
Which control do I need?
Compared with on/off, modulating (0–10 V/4–20 mA) provides more precise control.
When should I choose spring return?
In the event of a power failure, the valve automatically returns to a safe position; thus increasing operational reliability.
Does this fit into my system?
Yes, and it also connects to common HVAC and process control systems.
