HIMA F3331 safety-related 8-channel digital output module

HIMA F3331 is a safety-related 8-channel digital output module originating from Germany. It is widely used in safety-critical industrial scenarios due to its integrated safety protection functions and automatic testing capabilities, and has obtained SIL 3 certification which complies with the IEC 61508 standard. The detailed information is as follows:

Core Electrical and Channel Parameters

Parameter Category	Specific Details
Channel Configuration	It is an 8-fold output module with 8 digital output channels, which can meet the control needs of multiple sets of equipment in small and medium-sized safety systems at the same time.
Load Capacity	It is compatible with multiple load types. It can carry resistive or inductive loads up to 500mA (12W), and the maximum load for lamp connection is 4W, which is suitable for controlling common industrial actuators, indicator lights and other equipment.
Voltage and Current Indicators	The typical applicable voltage is 24V DC. The internal voltage drop is up to 2V when the load is 500mA; the undervoltage trip occurs when the voltage is ≤16V, and the maximum output voltage is 1.5V when the module is reset. The maximum leakage current of the output terminal is 350μA, and the maximum current input of the watchdog is 30mA.
