Product Description

The Yokogawa ADV869-P00 is a high-density integrated digital I/O module designed for ST control architectures. It combines 32 isolated digital input channels and 32 transistor-based digital output channels in a single compact module, reducing hardware footprint and simplifying cabinet design.

Equipped with specialized firmware, the module supports pulse width modulation (PWM) and time-proportional output, making it suitable for processes requiring variable duty cycles. With robust channel-to-channel isolation and fast response times, the ADV869-P00 ensures high data integrity and precise execution of discrete control tasks across power, chemical, and manufacturing applications.

Technical Specifications

Functional Applications

• Bi-Directional Process Control
  Monitor field switch states while simultaneously controlling solenoid valves or indicators.

• Energy Management
  Read pulse-based meter signals via the input channels and operate auxiliary equipment via outputs.

• Machine and Skid Automation
  High-density I/O for interlocking, sequence control, and integrated automation in compact control panels.

Technical FAQ

Q: Can the ADV869-P00 handle both pulse and steady-state signals?
A: Yes. Input channels support standard ON/OFF monitoring, while output channels provide continuous ON/OFF control or pulse-width/time-proportional operation.

Q: How is the isolation structured?
A: Commons are provided for every 16 channels, ensuring group isolation so electrical disturbances in one group do not affect others.

Q: Does the module require an external power source for outputs?
A: Yes. A 24 V DC external supply is needed to drive the transistor outputs and the connected field devices.
