PCU Specification
The Process Control Unit (PCU) operates on a 24V DC power supply with a voltage range of 18 to 31.2V. It consumes 8W of power and functions within a temperature range of -10°C to +70°C with 96% non-condensing humidity. It includes two LAN ports, one RS-232C port, four RS-485 ports, and six DIO ports. The PCU features a power-on self-test, watchdog timer, and low voltage detection.

VDU Specification
The Video Display Unit (VDU) is powered by a 24V DC supply, consuming up to 35W. It operates between 0°C and +55°C and weighs 6.1kg. It includes an Intel Core2Duo Processor, 3.5GB DDR2 RAM, and supports UXGA resolution. The VDU features multiple I/O ports and runs on Windows Embedded Standard 7.

EAP Specification
The Extension Alarm Panel (EAP) features a 7-inch wide TFT LCD with touch panel, supporting 65,536 colors. It operates on a 24V DC power supply with a consumption of 9.6W. The EAP includes dual Ethernet LAN interfaces and supports RS-485 communication.

AI/AO Specification
The Analog Input/Output (AI/AO) units operate on a 24V DC supply, consuming 16W. They support various signal types including current, voltage, and potentiometer inputs. The units feature self-test capabilities and earth leakage detection.

DI/DO Specification
The Digital Input/Output (DI/DO) units also operate on a 24V DC supply, with power consumption of 6W for DI and 12W for DO. They support dry contact inputs and relay outputs, with self-test and earth leakage detection features.

Multifunctional PCU
The PCU is designed for data measurement, alarm monitoring, and control tasks. It supports high-speed sampling at 20 ms intervals, aiding in detailed data analysis.

Installation and Configuration
The TERANET 50X system simplifies installation by using the ship's backbone LAN. It allows for easy modification of I/O signal types and system configuration without proprietary devices.

Reliability Features
The system is designed to be maintenance-free with fan-less, HDD-less, and battery-less components, ensuring high reliability.

RSTP HUB Specification
The RSTP Hub supports a 24V DC power supply, consuming 6W. It includes eight RJ45 ports and supports RSTP, SNMP, and VLAN for enhanced network reliability and security.

System Configuration
The TERANET 50X system allows for direct connection of the extension alarm system to the ship's LAN, improving reliability by processing alarms independently of the central system.
