HIMA F3331 Digital Output Module

Multiple Load Driving: It can handle resistive loads or inductive loads, with a maximum load current of up to 500mA (12W). It can also connect lamps with a maximum power of 4W, featuring a wide range of applications.

Safe Shutdown and Monitoring: Equipped with an integrated safe shutdown function, along with safety isolation and line monitoring. In case of L power supply interruption, there will be no output signal, which can effectively avoid dangerous situations.

Automatic Testing: Automatic testing can be performed during operation. The main test procedures include output signal readback, switching capability of test signals, crosstalk testing (walking bit test), and line monitoring to ensure the module works properly.

Number of Channels: Usually an 8-channel output module, which can control multiple external devices simultaneously.

Safety Level: Achieves SIL 3 certification (in compliance with IEC 61508 standard), with high safety performance.

Power Supply Voltage: Generally 24V DC, but some data shows that there is a version with 220V voltage specification.

Output Frequency: Some models can reach an output frequency of 30kHz, which can meet some occasions with requirements for output speed.

Operating Temperature: The operating temperature range is generally -20℃ to +60℃, but some modules can work in an environment of -40℃ to +85℃.

Protection Level: The protection level is usually IP20, and versions with higher protection levels can also be provided according to requirements.

Electrical Isolation: Using optoelectronic isolation or electromagnetic isolation technology, the control circuit inside the module is completely isolated from the power circuit of external executive equipment, preventing external high voltage, surges, or noise interference from entering the control system, and also avoiding the spread of internal faults to external equipment.

Output Driving: The safety-verified instructions are transmitted to the output drive circuit, and the module outputs corresponding digital signals (usually 24V DC switching signals) according to the instructions to drive external actuators (such as safety valves, emergency stop devices, contactors, etc.) to act.
Each output channel is independently controlled and can drive the load separately, ensuring that a single channel fault does not affect the normal operation of other channels.
