Technical Specifications

Power Supply Parameters
- The power supply voltage ranges from 20V DC to 35V DC. The maximum power consumption of the module is 2.0W, and it weighs 140 grams, which helps reduce the overall energy consumption and weight of the control cabinet.
- The maximum voltage tolerance of the related circuits reaches 253V RMS, which can adapt to the voltage fluctuations in industrial power supply environments.
Input and Output Parameters
- For proximity detector input, it provides 7.0V – 9.0V DC excitation with a nominal 1kΩ resistance. The output turns on when the input exceeds 2.1mA and turns off when the input is less than 1.2mA, with a nominal switching hysteresis of 0.2mA.
- The safe – area pulse output has a maximum delay of 10μs, a maximum off – state voltage of 35V, a maximum off – state leakage current of 10μA, a maximum on – state resistance of 25Ω and a maximum on – state current of 50mA.
- The analog output signal ranges from 4mA to 20mA, with an accuracy better than 20μA at 20°C and a temperature drift of less than 14μA/°C. The maximum load resistance it can drive at 20mA is 450Ω.
- The relay alarm output can bear a maximum of 0.5A current at 35V DC.

Description

- Environmental and Physical Parameters
  - The operating temperature ranges from -20°C to +60°C, which is suitable for most indoor and outdoor industrial working environments.
  - It adopts 35mm DIN rail mounting and requires a 20mm clearance during installation to ensure good heat dissipation.
Functional Features
- High – Speed Pulse Isolation and Transmission
  - It achieves efficient isolation and transmission of pulses from devices in hazardous areas, with a maximum pulse delay of only 10μs. This high – speed response capability fully meets the application requirements of high pulse rate scenarios and ensures that pulse signals are not distorted during transmission between hazardous and safe areas.
- Dual Output Modes for Diversified Needs
  - It integrates both pulse output and analog output proportional to frequency. The pulse output repeats the original signal for digital control, while the 4 – 20mA analog output is convenient for connecting to display instruments and recording equipment. The matching relay output can be set as an alarm to meet different signal application requirements of industrial systems.
- Strong Compatibility and Standard Compliance
  - It is compatible with 2 – wire and 3 – wire switches and proximity detectors, and complies with Namur and BS EN 60947 – 5 – 6:2001 standards. It can be directly connected to most common pulse signal devices on the market without additional adaptation components.
- Easy Installation and Maintenance
  - The plug – in power and signal connectors allow quick disassembly and assembly during maintenance. The compact 16mm – wide design enables intensive installation in control cabinets, improving space utilization. Meanwhile, it is compatible with the previous MTL 5000 series, facilitating the upgrading and replacement of old systems.
Application Scenarios
- Oil and Gas Industry
  - It is installed in onshore oil refineries and offshore drilling platforms. It connects pulse transmitters for flow and pressure detection in Zone 0 hazardous areas, transmits pulse signals to the safe – area flow computing system, and the analog output provides continuous flow data for monitoring. The relay alarm promptly notifies staff of abnormal flow, preventing leakage accidents.
- Conveyor and Material Handling Systems
  - In large logistics warehouses and industrial material workshops, it connects proximity detectors on conveyor belts in flammable dust hazardous areas. It transmits pulse signals reflecting the running speed and position of the conveyor belt to the safe – area control system, and triggers an alarm through the relay when the conveyor belt malfunctions, ensuring the safety of material transportation.
- Chemical Plants
  - It is used in Zone 0, IIC hazardous areas such as reaction kettles and chemical storage tanks. It connects pulse – type level detectors to isolate and transmit level pulse signals to the central control room. The analog output converts the level into a 4 – 20mA signal for display, helping operators grasp the material storage status in real time and avoid overfilling and leakage.
- Tank Level Detection in Storage Terminals
  - In petrochemical and chemical storage terminals, it matches with pulse – output level sensors on storage tanks in hazardous areas. It transmits the tank level pulse signals to the safe – area monitoring platform. The high – speed response ensures the timeliness of level data updates, and the relay alarm function can be activated when the level reaches the upper or lower limit, ensuring the safety of storage operations.
- Emergency Shutdown Systems
  - In industrial sites requiring high safety levels, it is integrated into emergency shutdown systems. It connects emergency stop switches and proximity safety detectors in hazardous areas. Once an emergency occurs, the pulse signal of the switch is quickly transmitted to the safe – area control unit through it to trigger the shutdown procedure, minimizing accident losses.
