ATC5S-00 | Yokogawa CENTUM VP Digital Output Module

Product Overview

The Yokogawa ATC5S-00 functions as a high-integrity digital output interface specifically engineered for CENTUM VP and ProSafe-RS control architectures. This module executes precise switching commands for field-side devices, such as solenoid valves, actuators, and status indicators. By utilizing dedicated hardware isolation for each channel, the ATC5S-00 maintains superior signal purity even in electrically turbulent plant environments. We supply this module as 100% Brand New and original, ensuring factory-certified performance for your mission-critical DCS or SIS network.

Engineering Advantages

The ATC5S-00 addresses rigorous technical requirements through advanced circuit engineering:

• Total Galvanic Isolation: The module features a 1500 VAC isolation barrier between the internal system logic and field wiring. This architecture prevents ground loops and blocks high-voltage transients from migrating to the central processor, effectively safeguarding the controller’s backplane.

• High-Speed Logic Execution: With a response time of 5 ms or less, the module enables real-time synchronization between the controller's logic and field actuators. This speed proves essential for emergency shutdown (ESD) sequences and high-frequency process switching.

• Optimized Thermal Dissipation: The module consumes only 2.5 W during typical operation. This low power draw reduces the heat load within the I/O nest, allowing for denser module packing without the risk of thermal derating or premature component failure.

• Seamless SIS Integration: Unlike generic I/O, the ATC5S-00 interfaces directly with ProSafe-RS systems. It meets the stringent reliability standards required for safety instrumented systems, providing a stable platform for both basic control and safety-related functions.

FAQs

Which Yokogawa systems support the ATC5S-00?

The ATC5S-00 integrates natively with CENTUM VP (DCS) and ProSafe-RS (SIS) platforms. It fits standard Yokogawa system racks and communicates directly via the system bus without requiring specialized protocol converters.

What is the maximum current this module can drive?

Each of the 8 channels supports a maximum continuous load of 0.5 A. This capacity allows the module to drive most industrial-grade solenoids and interposing relays directly from the I/O rack.

How does the module handle high-humidity environments?

The ATC5S-00 features industrial coatings that allow operation in environments with up to 90% non-condensing relative humidity. This robust build prevents moisture ingress and terminal oxidation in typical process plant conditions.

Does the module require external fuses for each channel?

While the module includes internal protection, we recommend installing external fast-acting fuses or circuit breakers for field wiring to prevent permanent damage from short circuits or over-current events at the device level.
