EnglishThe ICS Triplex 3401 Digital Input Module is a safety-critical input module designed for use in distributed control systems (DCS) and emergency shutdown systems.
Description:
The ICS Triplex 3401 is part of the Trusted TMR (Triple Modular Redundant) system, which is renowned for its reliability and fault-tolerant capabilities. This digital input module is typically used in safety-related applications where high availability and fail-safe operation are critical. The 3401 module monitors the status of digital inputs from field devices such as switches, sensors, or contacts, and sends this data to the controller for processing.
Triple Modular Redundancy (TMR): Ensures high reliability and continuous operation even in the event of a hardware failure.
Fault Detection: The module can detect and signal failures such as stuck-on or stuck-off signals.
Diagnostic Coverage: Includes advanced diagnostics to monitor the health of both the field devices and the module itself.
Key Parameters:
Input Voltage Range: Typically operates with a voltage range suited for standard industrial digital inputs (often 24V DC).
Channel Count: Supports 40 digital input channels.
Input Isolation: Provides electrical isolation between channels to prevent interference and enhance safety.
Operating Temperature: Typically designed for industrial environments, capable of operating within a range of -40°C to +70°C.
