        Description
        The ICS Triplex T3401 DC Digital Input Module is engineered with 16 input circuits divided into two isolated groups of eight channels, enabling structured signal acquisition for industrial control applications. It operates within a voltage range of 14 to 30 VDC and supports a turn-on threshold of 12 VDC minimum with a turn-off limit of 4.7 VDC maximum. With an input current of 8.7 mA, the T3401 DC Digital Input Module ensures consistent signal detection across field devices while maintaining stable electrical performance.

        One of the key strengths of the T3401 DC Digital Input Module is its triplicated I/O Safetybus interface, which ensures that no single failure can compromise system operation. The module supports fault-tolerant configurations when operated in parallel with redundant modules, allowing continuous system operation even during maintenance or replacement. In comparison to non-redundant input modules in the same ICS Triplex series, the T3401 DC Digital Input Module offers significantly higher system availability due to its built-in voting and redundancy logic.

        The T3401 DC Digital Input Module provides strong electrical isolation, with a minimum rating of 2500 volts between field wiring and logic circuits as well as between input groups. This isolation protects internal circuitry from electrical disturbances such as transients and over-voltages. The module also features automatic self-testing of Safetybus circuits and logic functions, ensuring continuous diagnostic coverage and reliable operation of the T3401 DC Digital Input Module in safety systems.

        Thermal performance and operational durability are also key aspects of the T3401 DC Digital Input Module, with power dissipation of approximately 10 watts and heat output of 34 BTUs/hour. It operates reliably in environments from 0°C to 60°C and can be stored between -40°C and 85°C. With hot-replaceable capability, the T3401 DC Digital Input Module allows maintenance without interrupting system operation, making it suitable for continuous industrial processes.
