Product Description

HIMA F3405 Relay Amplifier Module

Functional Features:

Fail-Safe Design: Equipped with a fail-safe function and built-in fail-safe logic. If any part of the system fails, the module will operate in a predefined safe state, which can effectively protect personnel and assets. It is suitable for occasions with extremely high safety requirements.
Multi-Channel Independent Control: Has 4 independent channels, which can control 4 different loads respectively and efficiently process various input signals. Each channel has been carefully tested to ensure accurate activation of the relay under various conditions.
Wide Temperature Operating Range: The operating temperature range is usually -25℃ to +70℃, which can maintain stable performance under harsh environmental conditions and adapt to different regions and working conditions.
Digital Input Compatibility: Compatible with digital inputs, can adapt to a wide range of control signals, and can be flexibly applied to various industrial scenarios such as process automation, mechanical control, or safety-critical systems.

Technical Parameters:

Type: Relay amplifier.
Number of Channels: 4 channels.
Operating Voltage: Usually 24V DC.
Input Current: Maximum 10mA per channel.
Load Capacity: Up to 5A@24V DC per channel.
Protection Level: Generally IP20.
Installation Method: Panel mounting can be adopted.
Weight: Approximately 0.2kg.

Application Fields: Due to its high safety and reliability, the F3405 module is widely used in industries such as chemical industry, petroleum, and electric power. For example, in chemical production, it can be used to control the opening and closing of key valves to ensure the safety of the production process; in power plants, it can be used in protection systems to safely control equipment such as generators and transformers.

Working Principle:

Receiving and Processing of Control Signals
The module receives low-level digital control signals (usually 24V DC logic signals) from the upper-level safety controller (such as HIMA F3 series controllers) through the input interface. These signals carry instructions to "activate" or "deactivate" the relay.
The internal circuit performs validity verification on the input signals (such as detection of signal duration and level stability), filters out interference or false trigger signals, and ensures that only legal instructions are responded to.
Signal Amplification and Relay Driving
The received control signals are amplified in power by the internal amplifier circuit: Since the signal power output by the controller is weak (usually a maximum of 10mA per channel), it cannot directly drive the relay coil. The module increases the current/power through the amplifier circuit to make it sufficient to drive the relay action (each channel can output a maximum of 5A@24V DC).
The amplified signal is transmitted to the relay coil of the corresponding channel, controlling the relay contacts to close (conduct) or open (cut off), thereby realizing the switch control of external loads (such as valves, contactors, alarm devices, etc.).
Fail-Safe Mechanism and Status Monitoring
Fail-safe logic: The module has a built-in fail-safe design. When it detects input signal loss, power interruption, internal circuit faults (such as abnormal amplifiers, relay sticking), etc., it will automatically trigger the preset "safe state"—usually the relay contacts open (cut off the load power supply), avoiding dangers caused by misoperation in the fault state.
Real-time monitoring: It monitors the status of relays in each channel (such as whether the contacts are closed, whether the coil is energized), power supply voltage, input signal integrity, etc., through built-in sensors, and feeds back the monitoring data to the upper-level controller, facilitating the system to grasp the operating status of the module in real time.
Electrical Isolation and Protection
It adopts optoelectronic isolation or electromagnetic isolation technology to completely isolate the input control circuit, internal amplifier circuit, and external load circuit, preventing external high voltage, surges, or load-side faults (such as short circuits) from reversely affecting the controller or the internal circuit of the module, and improving the anti-interference ability and safety of the system.
Some channels have overcurrent protection function. When the load current exceeds the rated value (such as 5A), it will automatically limit the output or cut off the channel to protect the relay and external equipment from damage.

Summary:
The core function of the HIMA F3405 module is "safe amplification and driving": it drives relays by amplifying weak control signals to realize safe control of high-power loads; at the same time, relying on fail-safe design and real-time monitoring, it ensures accurate response to instructions under normal working conditions and automatically switches to a safe state in case of faults. It is suitable for scenarios with extremely high requirements for load control safety in industries such as chemical industry and electric power (such as driving key valves and emergency shutdown devices).
