The Yokogawa ADV869-P01 is a mixed digital I/O module designed for advanced industrial automation systems. It combines 32 digital input channels with 32 digital output channels in a single compact module. The suffix “-P01” indicates this variant supports pulse-width and time-proportional output modes as well as a more robust environmental specification (for demanding installations).
This module is ideal for modular I/O racks or distributed control systems (DCS) where space is limited but I/O density and timing control are required. The integrated design allows status monitoring (inputs) and control actuation (outputs) in one module, simplifying wiring and system architecture.
| Parameter | Specification |
|---|---|
| Number of Input Channels | 32 |
| Number of Output Channels | 32 |
| Input Type | 24 V DC contact/voltage input |
| Output Type | 24 V DC transistor current-sink outputs |
| Pulse-Width / Time-Proportional Output Range | ~8 ms to ~7200 s |
| Max Load Current per Output Channel | ~100 mA |
| OFF-state Leakage Current (Outputs) | ≤ ~0.1 mA per channel |
| ON-state Voltage Drop (Outputs) | ≤ ~2 V DC (approx) |
| Response Time (Inputs) | Millisecond-class (≈8 ms) |
| Response Time (Outputs) | ≤ ~10-16 ms depending on mode |
| Isolation | Fully isolated between input, output groups and system |
| Dimensions | 144 mm (W) × 100 mm (H) × 30 mm (D) |
| Weight | ~0.32 kg (approx) |
| Supply Voltage | 24 V DC field I/O |
| Mounting / Format | Plug-in rack module, industrial I/O rack |
| Environment | Suitable for higher ambient temperature or harsher conditions relative to base models |
| Redundancy Support | Compatible with dual-redundant I/O rack systems |
Process control plants where both many status signals and many control outputs are needed together (e.g., valve position feedback + actuators)
Batch or sequencing operations where timed digital outputs (pulse/ proportional) are required alongside discrete inputs
Manufacturing automation like machine lines, packaging, robotics that monitor sensors and drive actuators with timing control
Utilities / water-treatment: controlling pumps, gates, mixers with timed outputs and monitoring sensors/alarms
Remote I/O installations: near the field where cable runs must be minimized and mixed I/O modules reduce cabinet count
High-availability systems: where a robust module with higher spec is needed for redundant remote racks in critical installations
High I/O density: 32 inputs + 32 outputs in one module reduce cabinet size and system complexity
Advanced output timing: Pulse-width and time-proportional modes give control over duty cycles or sequenced actuation
Robust environment rating: The “P01” variant is built for harsher ambient conditions and adds resilience
Combined I/O simplifies wiring: One module handles both status and actuation rather than two separate modules
Compact & lightweight: At about 0.32 kg and standard modular size, it fits well into dense I/O racks
Isolation protects system: Strong isolation between groups safeguards against electrical noise and field disturbances
Scalable modular architecture: Works in rack systems, easy to expand or replace
Cost-efficient design: Combining functions in one card reduces component count, wiring, maintenance overhead
