ATD5S-00 | Yokogawa Pressure Clamp Terminal Block for Digital Output

Product Overview

The Yokogawa ATD5S-00 functions as a high-density, 32-point pressure clamp terminal block specifically engineered for digital output signal distribution in industrial automation environments. It facilitates secure, vibration-proof connections between the control system and field actuators. We supply this unit as 100% Brand New and Original, ensuring your DCS (Distributed Control System) maintains peak signal integrity and meets stringent regulatory standards.

Part Number Breakdown: ATD5S-00

Yokogawa utilizes the following suffix logic to define the hardware capabilities of the ATD5S series:

Technical Specifications

The ATD5S-00 combines a compact form factor with robust environmental hardening:

• Channel Capacity: 32-channel digital output

• Connection Method: Pressure clamp terminal (screwless)

• Environmental Standard: ISA Standard G3 compliant (Conformal coating)

• Surge Protection: None (Configuration -0)

• Mounting Compatibility: Standard 19-inch rack / DIN rail options

• Weight: Approximately 0.20 kg

• Application: Industrial automation and process control systems

Engineering Advantages

The ATD5S-00 optimizes field wiring and protects electronic hardware in demanding process plants:

• Corrosion Resistance in Harsh Zones: This terminal block complies with ISA Standard G3, protecting copper traces and contact points from atmospheric corrosion caused by $H_2S$, $SO_2$, and high humidity. This feature ensures long-term electrical conductivity in wastewater treatment and chemical processing facilities.

• Maintenance-Free Pressure Clamps: The spring-loaded pressure clamp mechanism maintains constant tension on the conductor. This design eliminates the need for periodic re-tightening—a common requirement with traditional screw terminals—and prevents signal loss caused by mechanical vibration from nearby rotating machinery.

• High-Density Signal Management: By packing 32 digital output points into a slim 0.20 kg footprint, the ATD5S-00 significantly reduces the amount of rail space required in marshalling cabinets. This allows engineers to increase I/O density without expanding the physical enclosure size.

• Simplified Commissioning: The tool-free wiring capability speeds up installation. Technicians insert stripped wires directly into the clamp, reducing labor costs and eliminating the risk of over-tightening or stripping screw threads during the setup phase.

FAQs

• Does the ATD5S-00 require ferrules for stranded wire?

  While the pressure clamp secures bare stranded wire effectively, we recommend using insulated ferrules to prevent stray strands from causing short circuits in high-density 32-point configurations.

• What happens if I encounter a voltage surge without a surge absorber?

  The ATD5S-00 configuration lacks an internal surge absorber. In environments prone to lightning or heavy inductive switching, you must install external surge protection devices to prevent transient voltages from reaching your I/O modules.

• Can I use this terminal block for analog output signals?

  Yokogawa specifically designs the ATD5S series for digital output logic levels. Using it for sensitive analog signals may introduce impedance mismatches; therefore, we recommend using the dedicated analog series for precision loops.

• Is this unit compatible with existing 19-inch racks?

  Yes, the ATD5S-00 adheres to standard Yokogawa mounting dimensions, fitting seamlessly into existing 19-inch rack-mounted DCS cabinets or DIN rail assemblies.
