Sensor-controlled DC relay

DC Sensor Controlled Relay – Intelligent Automation Solution for Industrial Applications

Introduction to Industrial Relay Control

The DC Sensor Controlled Relay from AKCP represents a modern solution for industrial automation and monitoring systems. This intelligent relay circuit enables the remote control of electrical devices via the internet and automatically responds to sensor alarms. Remote control of devices is realized through seamless integration with AKCP base units and a comprehensive selection of sensors.

Function Principle and Automation

Relay control is accomplished via an intelligent connection between sensors and circuits. The system can, for example, automatically switch on a fan when the room temperature exceeds a defined threshold value or activate lighting when a motion detector is triggered. This type of process automation is particularly valuable in industrial facilities, data centers, and monitoring systems.

The DC Sensor Controlled Relay uses an auto-sense function that significantly simplifies configuration. Via a user-friendly web interface, users can set the desired parameters and configure alarm notifications by email or SNMP trap. This remote monitoring enables proactive maintenance and a rapid response to critical situations.

Technical Specifications and Performance Features

Electrical Characteristics

The DC Relay operates with an input voltage of up to 125 VDC and also provides an output voltage of up to 125 VDC. The relay contacts are designed for a rated load of 10 amperes at 30 VDC and use AgCdO contact material for high reliability and long service life.

The switching capacity is up to 480 watts with a resistive load and 350 watts with an inductive load (L/R = 7 ms). A 10-ampere fuse at 125 VDC protects the system from overload. The maximum switching frequency is 18,000 operations per minute without load and 1,800 operations per minute at rated load.

Operating Conditions and Environment

The industrial relay is designed for use in demanding environments. The operating temperature range extends from -40°C to 70°C, while the storage temperature can range from -40°C to 70°C. This robustness makes the system ideal for industrial environments with extreme conditions.

Communication and Connectivity

The interface is via an RJ-45 socket with UTP CAT5e/6 cable. The communication cable can be up to 100 feet (30 meters) long, enabling flexible installation. Power is supplied directly via the control unit, so no additional power source is required. The typical power consumption is 471 mW at 94.20 mA.

Status Display and Monitoring

The system features comprehensive LED status indicators for various operating parameters:

• Input voltage (LED display)
• Output voltage (LED display)
• Sensor power supply (LED display)
• Relay status (LED display)

These visual indicators enable rapid diagnosis of the system status and support maintenance and troubleshooting.
