Core performance characteristics

1. Extremely compact design, space utilization breakthrough

The module adopts the ultimate miniaturization structure design, with a core size of only 22.5mm × 17.4mm × 10mm, reducing its volume by more than 60% compared to traditional industrial control modules, and weighing only about 0.05kg. It can be easily installed on micro rails, narrow cavities inside equipment, and embedded installation positions, greatly improving space utilization. In response to the installation requirements of small industrial equipment and compact control systems, the module adopts a non redundant structure design, maximizing the simplification of volume while ensuring core functions. At the same time, it is equipped with micro pluggable terminal blocks, which balance installation convenience and space adaptability, solving the pain point of traditional modules that cannot be installed in narrow spaces.

2. Highly integrated and multifunctional, suitable for small control needs

The module adopts a highly integrated circuit design, integrating multi-channel signal processing, logic control, and data transmission functions within a miniature volume. The standard configuration includes 2 analog input channels, 2 digital input channels, and 1 digital output channel. The analog input channel supports 0-10V DC voltage signals and 4-20mA current signals, and can be directly adapted to small pressure sensors, temperature sensors, and other field devices; The digital input and output channels support 12-24V DC signals, which can achieve functions such as small actuator control and equipment status monitoring. Some sub models can support thermocouple (K/J type) and thermistor (PT100) inputs, adapting to the temperature monitoring needs of small industrial equipment without the need for additional dedicated modules, greatly simplifying the architecture of small control systems.

3. Industrial grade anti-interference, stable operation guarantee

Despite its compact size, the module still adopts full industrial grade design standards, with built-in multi-channel optoelectronic isolation circuits to achieve electrical isolation between input/output signals and core control circuits. The isolation withstand voltage can reach 1kV AC/1 minute, effectively blocking electromagnetic interference, surge voltage, and ground loop interference in industrial sites. The module is equipped with miniature Transorb surge protection devices, which can withstand instantaneous 30V DC surge impact. At the same time, it adopts anti electromagnetic radiation packaging materials, which comply with the IEC 61000-4 electromagnetic compatibility standard, ensuring stable operation in complex electromagnetic environments with dense installation of small equipment. In addition, the module adopts a low-power design, with a normal operating current of only 20mA or less, reducing energy consumption and heat generation, and adapting to the heat dissipation needs of sealed and narrow installation spaces.

4. Flexible configuration and adaptation, easy installation and maintenance

The module supports parameter configuration through a micro handheld terminal (such as Yokogawa JHT200), which needs to be connected with a dedicated adapter (model E9786WH). It can flexibly set signal type, range, alarm threshold and other parameters without disassembling the module, and can be configured and adjusted to meet the on-site maintenance needs of small devices. Adopting a micro pluggable terminal design, the wiring operation is convenient, and cables can be quickly plugged and unplugged during later maintenance, greatly improving maintenance efficiency. At the same time, the module supports two installation methods: DIN micro rail installation and embedded buckle installation, which can be flexibly selected according to the actual installation space, further enhancing the flexibility of system integration.

Installation and wiring specifications

1. Preparation before installation

Before installation, it is necessary to confirm that the module size matches the installation space, check that the module appearance is not damaged, the micro wiring terminals are not bent or deformed, and the embedded LED indicator lights are not damaged. Confirm that the installation environment meets the requirements of module environmental parameters, and stay away from strong electromagnetic interference sources (such as micro frequency converters, high-voltage micro components, etc.), high temperature heat sources, and humid areas; Due to the small size and limited heat dissipation space of the module, the installation position needs to ensure smooth ventilation and avoid excessive dense installation with other heating elements. Installation personnel need to have qualifications for installing small industrial control equipment, be familiar with module installation manuals, prepare micro installation tools (such as micro screwdrivers), compatible micro wiring terminals, and fine shielded cables in advance to avoid module damage caused by improper tools.

2. Key points of installation operation

Choose the appropriate installation method based on the installation space: When using DIN micro rail installation, align the module buckle with the micro rail and smoothly push it in to ensure that the buckle is fully engaged and avoid module detachment due to vibration; When using embedded snap fasteners for installation, it is necessary to ensure that the size of the installation cavity matches the module, gently press the module until the buckle locks, and do not apply too much force to avoid damaging the module housing. The installation direction should follow the positive direction of the module identification, ensuring that the LED indicator light is visible and the wiring terminals are operable. A minimum distance of 2mm should be maintained between modules and adjacent components to ensure adequate space for heat dissipation and wiring operations. After installation, gently pull the module to confirm that it is securely fixed without any looseness.

3. Wiring operation specifications

Before wiring, all associated equipment power must be cut off, including module power supply, backend control equipment power supply, and on-site sensor power supply. After confirming that the voltage has dropped to a safe level, wiring operations can be carried out to avoid electric shock or module damage. Due to the use of miniature wiring terminals in the module, it is recommended to use thin wires with a size of 0.5-0.75mm ², and the stripping length should be controlled within 3-5mm to avoid short circuits caused by excessively long wires. Micro shielded twisted pair cables are preferred for analog signals, with a cable length not exceeding 50m. The shielding layer is grounded at one end (with a grounding resistance of less than 10 Ω) to avoid parallel installation with power cables. Strictly distinguish between analog input, digital input, digital output, and power terminals when wiring, and connect them accurately according to the wiring manual to avoid module failures caused by incorrect terminal connections. After the wiring is completed, gently pull each wire to confirm that the connection is firm, organize the cables to avoid compressing the module or blocking the indicator light, and ensure that there are no short circuits or virtual connections.
