Yokogawa ATD5S-00 Pressure Clamp Terminal Block

The Yokogawa ATD5S-00, also cataloged as the ATD5S Terminal Block, operates as a dedicated hardware component for digital output signal termination within Yokogawa CENTUM VP control systems.

Hardware Specifications

DCS Signal Integrity & Process Control Architecture

• 4-20 mA HART Loop & Digital Switching Isolation: Facilitates direct physical wiring interfaces for 32 digital output channels, preventing cross-channel electrical noise propagation to CENTUM VP FIO cards.
• Integrated Field Surge Suppression: Features built-in surge absorbers to suppress high-voltage field transients and fulfill EN 61000-6-2 surge immunity limits.
• Channel-to-Channel Environmental Protection: Incorporates ISA Standard G3 class conformal treatment options to protect internal terminal connection points from corrosive gaseous contaminants.

Frequently Asked Questions

Q: Can the ATD5S-00 terminal block be removed from the FIO module while field wiring remains physically clamped?

A: Yes, the terminal assembly unlatches directly from the front face of the FIO card without necessitating wire insertion release or rewiring operations.

Q: Does the integrated surge absorber require external earth grounding connections?

A: Yes, transient voltage suppression relies on low-impedance ground bonding through the FIO mounting baseplate or rail assembly to route surge current to functional earth.

Field Installation Guidelines

Mount the ATD5S-00 terminal block directly onto the corresponding 32-channel digital output module in the CENTUM VP cabinet slot. Strip field conductor ends to recommended gauge length (8 mm to 10 mm) without damaging metal strands, and press each wire firmly into the pressure clamp terminal point. Ensure the cabinet rail or baseplate is bonded to functional earth to activate the integrated surge absorber protection in compliance with EN 61000-6-2 standards.
