P0973KJ

Description

Parameter Specifications

1. Power Supply
   The P0973KJ typically operates on a 24V DC power supply. The power consumption is relatively low, around 4 – 7W, which is energy – efficient for long – term continuous operation in industrial or similar settings.
2. Input/Output Channels
   • Digital Inputs: It is equipped with 8 digital input channels. These inputs are designed to interface with common digital sensors such as proximity sensors, reed switches, and limit switches. The input voltage range is usually 18 – 30V DC, ensuring compatibility with a wide variety of sensors used in industrial automation.
   • Digital Outputs: There are 4 digital output channels. Each output channel can drive a resistive load of up to 1A and an inductive load of up to 0.5A. This allows it to control small – scale actuators like relays, solenoid valves, and indicator lights.
3. Communication Interface
   The device supports the Modbus RTU communication protocol over an RS – 485 interface. With a communication speed of up to 9600 bps, it can effectively communicate with other devices in an industrial network, such as Programmable Logic Controllers (PLCs), Human – Machine Interfaces (HMIs), and Supervisory Control and Data Acquisition (SCADA) systems.

Uses

1. Industrial Automation
   • In manufacturing plants, the P0973KJ can be used to monitor and control the basic operations of production lines. For example, it can detect the presence of workpieces on a conveyor using digital inputs and control the movement of small – scale conveyors or the activation of simple processing equipment via digital outputs.
2. Building Automation
   • In commercial or residential buildings, it can manage simple building functions. It can be connected to door sensors and occupancy sensors to control lighting in small areas like storage rooms or corridors. When a person enters a room, the sensor signals are received by the digital inputs, and the device can turn on the lights through the digital outputs.
3. Agricultural Automation (Small – Scale)
   • In small – scale agricultural setups, it can be used to monitor environmental conditions. By connecting to sensors that detect soil moisture or temperature, it can control small water pumps or heaters. If the soil is too dry, the digital input will receive the signal, and the device can turn on the water pump via the digital output.

Weight and Dimensions

1. Weight
   The P0973KJ weighs approximately 0.3 – 0.5 kg, which is relatively light, making it easy to install and handle.
2. Dimensions
   It has a compact design with dimensions around 90mm (length) x 70mm (width) x 30mm (height). This small size enables it to be installed in tight spaces within control cabinets or on DIN rails.

Characteristics

1. Compact and Cost – Effective
   • Its small form factor and relatively low cost make it an attractive option for small – scale automation projects where budget and space are limited.
2. Easy to Configure
   • The device can be easily configured using simple software tools. Users can set up input/output parameters, communication settings, etc., without requiring in – depth technical knowledge.
3. Electrical Isolation
   • It features electrical isolation between input/output channels and the power supply. This helps prevent electrical interference and protects the device and connected equipment from damage.

Stability and Reliability

1. Robust Construction
   • The P0973KJ has a durable housing that can withstand normal industrial vibrations, dust, and moderate temperature variations.
2. Fault Protection
   • It is equipped with over – current and over – voltage protection circuits. These safeguard the device from electrical faults, ensuring reliable operation over time.
3. Long – Term Testing
   • The device has undergone long – term testing under various operating conditions to verify its stability and reliability, giving users confidence in its performance.

Actual Cases

1. Small – Scale Workshop
   • In a small – scale metalworking workshop, the P0973KJ was used to control a small grinding machine. It monitored the position of the workpiece on the workbench through a proximity sensor connected to the digital input. When the workpiece was in the correct position, the device sent a signal through the digital output to start the grinding machine. This simple automation improved the efficiency and safety of the grinding process.
2. Residential Basement Lighting
   • In a residential building, the P0973KJ was installed to control the lighting in the basement. It was connected to a motion sensor at the basement entrance. When the motion sensor detected movement, the digital input received the signal, and the device turned on the basement lights via the digital output. When there was no movement for a set period, the lights were turned off, resulting in energy savings.
