Hima F3237 Safety-Related Digital Input Module
Manufacturer: HIMA
Product Number: F3237
Category: 8-Channel Safety-Related Digital Input Module
Number of Channels: 8
Input Type: Proximity switches, NAMUR devices (DIN 19234), resistive sensors
Switching Time: Approx. 10 ms
Input Current Thresholds: 1 signal: 2.1-6.0 mA; 0 signal: 0.35-1.2 mA; wire break <0.28 mA
Line Impedance: ≤50 Ohm (per DIN 19234)
Power Consumption: 5V: 90 mA; 24V: 170 mA
Product Description
The HIMA F3237 is an eight-channel safety-related digital input module designed for use in industrial automation and safety systems. It supports the connection of proximity switches (including NAMUR devices according to DIN 19234) and resistor-wired sensors, while continuously monitoring wiring integrity such as short-circuit and wire-break detection. The module performs built-in self-tests during operation to ensure reliable performance.
It is ideal for safety-critical applications requiring high availability and functional safety up to SIL 3.
Main Features:
-
Eight isolated safety-related input channels
-
Supports NAMUR proximity sensors per DIN 19234
-
Continuous self-diagnostic and line-fault detection
-
Suitable for redundant safety architectures
-
Compact 4 TE plug-in module design
-
Typical switching time of approximately 10 ms
