The ICS Triplex T8461 is a high - performance digital output module designed for industrial control systems, especially suitable for applications that require high reliability and fault tolerance. Here are the detailed contents:
- Manufacturer: ICS Triplex
- Part Number: T8461
- Product Type: Digital Output Module
- Country of Origin: USA
- Dimensions: Approximately 39cm x 31cm x 9cm
- Weight: About 1.7 kg
- System Power Supply Voltage Range: 20 - 32VDC
- Operational Output/Field Voltage Range: 18 - 60VDC
- Output Channels: 40 digital output channels, which can interface with 40 field output devices
- Redundancy Design: Adopts a Triple Modular Redundant (TMR) architecture for each output channel. Each channel has three independent circuits that compare and vote on the output signals to ensure data accuracy and reliability
- Isolation: Has a 2500V impulse - withstand opto/galvanic isolation barrier to protect against electrical interference
- Diagnostic Function: Built - in comprehensive automatic diagnostic and self - test functions. Each channel has automatic line monitoring to detect open - circuit and short - circuit field wiring faults. There are also status LEDs for each channel on the front panel to indicate output status and field wiring faults, and module - level status LEDs to show module operation status and mode
- Protection Mechanism: Equipped with automatic over - current protection for each channel, no external fuses are required
- Event Reporting: On - board Sequence of Events (SOE) reporting with 1ms resolution, which can accurately record the order of output signal changes
- Hot - Swap Capability: Can be configured for online hot - swapping using dedicated Companion slots or SmartSlots, which improves system availability
- Operating Temperature Range: - 40°C to +85°C
- Humidity: 5% to 95% non - condensing
- Certification: TÜV certified to IEC 61508 SIL 3, which indicates its high reliability for safety - critical applications
- Industrial Automation: Used in industrial control systems to control various actuators, such as motors, valves, and relays
- Safety - Critical Systems: Widely used in safety - critical applications in oil and gas, chemical plants, power generation facilities, etc., due to its high - reliability and fault - tolerance design, ensuring the stable operation of the system under various conditions
