        Features:

        • Delivers 40 independent 4–20 mA output channels for precise multi-loop control.
        • Implements triple current-control architecture to maintain stable loop current during faults and hot swap.
        • Provides conformal coating and failsafe group switching for enhanced durability and system reliability.
        The ICS Triplex T8480C plays a key role in modern industrial automation systems where accurate analogue signal output is required. By combining current-controlled functionality with Trusted TMR architecture, the module ensures dependable performance in safety-critical environments. Its ability to maintain signal integrity under fault conditions makes it valuable in continuous process industries. The design aligns with systems that demand high availability and minimal downtime. With 40 channels available, the ICS Triplex T8480C supports complex control schemes efficiently. This makes it suitable for large-scale distributed control systems.

        In terms of functionality, the ICS Triplex T8480C introduces a unique switching mechanism that differs from standard analogue modules. The use of three current-controlling switches and three shutdown switches allows better management of output current. This approach helps balance load conditions and maintain stable output even during module replacement or failure scenarios. The internal grouping of channels further enhances protection through shared failsafe switching. As a result, the ICS Triplex T8480C provides both precision and resilience. These characteristics are essential for maintaining consistent process output.

        From a deployment perspective, the ICS Triplex T8480C adapts to various industrial environments with an operating temperature range of 0°C to +60°C. Installation via PD-8480 ensures compatibility within Trusted systems. While not intrinsically safe, the module can still be integrated into hazardous areas with appropriate protective measures. In explosion-proof enclosures, direct connection is permitted, simplifying certain installations. The ICS Triplex T8480C therefore balances flexibility with compliance. This combination makes it a practical solution for industries requiring robust and stable analogue output control.

        The T8480C ICS Triplex Trusted TMR Analogue Output Module (Coated) may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

        Description
        The ICS Triplex T8480C operates as a current-controlled analogue output module, offering 40 output channels with a 4–20 mA signal range for accurate process control. Unlike conventional analogue modules, the ICS Triplex T8480C behaves similarly to a digital output module in terms of termination and characteristics, while introducing current regulation capabilities. This structure allows it to support demanding industrial applications where consistent signal delivery is essential. With a power consumption of 22 W and an input range of 20–32 Vdc, the module integrates efficiently into existing Trusted TMR systems. The conformal coating further enhances durability in harsh environments.

        Internally, the ICS Triplex T8480C uses a specialized circuit architecture where channels are grouped and powered through a common failsafe switch. Instead of traditional FET switching, the module incorporates three current-controlling switches and three shutdown switches. This design enables the demand current to be distributed across three slices, ensuring that total loop current remains as constant as possible during fault conditions or hot-swap operations. Such a configuration improves system resilience and minimizes disruption in continuous processes. The ICS Triplex T8480C is therefore well suited for applications requiring high availability and fault tolerance.

        From an application perspective, the ICS Triplex T8480C is intended for use in industrial safety and control systems, particularly where analogue output stability is critical. The module is not intrinsically safe or non-incendive, meaning additional power-limiting devices are required when used in hazardous areas. However, direct connection is permitted in EEx "d" environments when installed within explosion-proof enclosures. With an operating temperature range of 0°C to +60°C and installation via PD-8480, the ICS Triplex T8480C supports flexible deployment across a wide range of industrial conditions while maintaining compliance with safety requirements.
