Overview
The HIMA F 3237 is an 8-fold input module specifically designed for safety-related applications. It connects safety proximity switches and resistor-wired sensors, ensuring continuous operation. Moreover, the module monitors input lines for wire breaks and short circuits, maintaining system reliability in critical environments.
Key Benefits of F 3237
- Safety-Certified: Complies with requirement class AK 1 to 6 for critical applications.
- Automatic Testing: Continuously tests switching capability, input filters, and module functionality.
- Short Circuit & Wire Break Detection: Protects systems from unexpected failures.
- LED Indicators: Provides operational status, though not tested in automatic self-tests.
- Flexible Sensor Compatibility: Supports DIN 19234 (NAMUR) proximity switches; external resistors can enhance non-standard switch functionality.
