7.1 Activity - Green LED indicates the device system status,

Device operating mode: blinks at a frequency of 2 times per second;
Successful completion of the software update process: blinks at a frequency of 4 times per second;

7.2 Error - Red LED indicates errors and traffic.

Device operating mode: If everything is normal, the LED is off; otherwise, it is constantly lit;
Software update mode: blinks at a rate of 2 times per second;

7.3 Alarm - The LED can be programmed via the user interface for alarm indication.

7.4 CAN - Green LED indicates CAN bus status.

LED blinks slowly - nothing is connected
LED blinks fast - configuration in progress
LED is constantly lit - connected to CAN devices

7.5 E1, E2 - LED status indicators for 12V 0.25A relay outputs.

LED ON (orange) - output is ON (initial state can be configured).
LED OFF (off) - output is OFF (initial state can be configured).

7.6 R1, R2, R3, R4, R5, R6, R7, R8 - LED status indicators for the status of x8 C13 outlets.

LED ON (orange) - relay is ON (initial state can be configured).
LED OFF (off) - output is OFF (initial state can be configured).

8. OUTLETS 1-8 - x8 C13 sockets 110-240V AC, 50/60 Hz.

9. INLET - C20 inlet, 110-240V AC, 50/60Hz, fuse 16A

10. INLET FUSE - Fuse 16A

11. OUTPUTS 12V 0.25A - 12V 0.25A (per output) terminal outputs (electronic relay). LED indicators are located on the front panel.

12. DRY CONTACT INPUTS 1...2 - Digital inputs (type IN).

13. CAN 1 / CAN 0 - Two digital RJ12 connectors for connecting CAN sensors/extensions/devices on a CAN bus.

Modules connected to these connectors can be interconnected.

14. SD Card - MicroSD card slot with eject mechanism. The card is required for data storage or “system recovery.”

15. Extension Slot - Only one of the two extensions can be installed: Modbus RTU extension or OSDP v2 reader extension. Ordered separately.

16. Chassis Grounding - Chassis grounding, M4 thread. Improves the equipment’s immunity against conducted and radiated RF interference.

Please contact a professional electrician before connecting it.

17. DC 12V BACKUP POWER - This is a backup power supply connection.

18. TEMPERATURE SENSOR - Accuracy +/- 1 °C.

19.1 Restart - The button restarts the device. Hold the button for 2 seconds and then release it, and the system will restart.

19.2 Factory reset - Resets settings to standard factory defaults. Hold the button pressed for more than 5 seconds.

The Error LED starts blinking. This indicates that the factory reset has been initiated. Wait 20-60 seconds for the system to restart.
The Activity LED starts blinking once the system has restarted. The device is now accessible.

20. N - R - DIP Switch is used for different system modes.

Normal mode: The switch is set to the left ←. The switch should always be in this position.
Device recovery: The switch is set to the right →. Used to load a clean system image from an SD card.

Areas of Application

The Didactum PDU 8T switched PDU with 8 outlets is designed for a wide range of applications, making it an indispensable tool in environments that require reliable power management and environmental monitoring. Here are some of its key areas of use:

• Data Center Management: The Didactum PDU 8T enables data center operators to efficiently manage the power supply of servers and network equipment. By remotely switching outlets on and off, technicians can perform remote reboots and ensure optimal load distribution, which is crucial to avoid overheating and ensure uptime.

• Environmental Monitoring: The device allows monitoring of critical environmental parameters such as temperature, humidity, voltage, and smoke. In data centers or server rooms, maintaining specific conditions is essential to prevent equipment damage. For example, a temperature rise detected by the Didactum PDU 8T can trigger alarms or automatically activate fans for cooling.

• Peripheral Device Control: The Didactum PDU 8T can be used to control peripheral devices such as fans, generators, and UPS systems. This functionality is especially useful during power outages, as the system can automatically switch to emergency power while managing other connected devices to maintain operation.

• Security Systems: With its ability to control doors and alarms, the Didactum PDU 8T acts as part of an integrated security system. It can manage access control systems and monitor unauthorized access to ensure that sensitive areas remain protected.

• Customizable Logic Schemes: Users can set up complex logic schemes to enable automated responses based on specific conditions. For example, the system can automatically activate dehumidifiers or fans when a humidity threshold is exceeded.

• Energy Data Management: By monitoring voltage and power consumption of various devices, the Didactum PDU 8T helps organizations optimize energy use and reduce costs. Alerts can be configured to notify operators of unusual consumption patterns that might indicate faulty equipment.

• Remote Monitoring and Management: The integrated web interface allows easy remote access, enabling IT personnel to monitor and control systems from anywhere. This feature is indispensable for companies with multiple locations or external management.

These applications highlight the versatility and importance of the Didactum PDU 8T in modern IT and facility management, helping organizations ensure operational efficiency, security, and reliability.
