| Suffix Code Meaning | “P60” means: “P” = has pulse width / time‑proportion output capabilities; “6” = with status display; “0” = basic / no explosion‑proof variant |
The ADV551‑P60 is a 32‑channel digital output module engineered for control systems that require more than just ON/OFF outputs — it includes pulse width and time‑proportional output capabilities, as well as visual status indicators per output channel. It is used where control of actuators, indicators, valves or alarms demands precise switching, feedback, and durability.
It is designed for 24 V DC systems with current sink outputs. The module includes electrical isolation between the outputs and the system, to protect against electrical noise, surges, and provide safety. The P60 variant is the “status display + pulse/timing output” version, though it does not include explosion‑proof rating.
Driving field devices (solenoids, indicator lights, alarms, valves) in process plants
Time‑proportioning control (e.g. modulation of valves or devices by varying ON/OFF duty cycles)
Systems where output status visualization (LED or equivalent) is useful for diagnostics and maintenance
Environments with standard industrial temperature/humidity (not extreme hazardous classification)
Use in control racks or IO nodes in distributed control systems (DCS)
High channel count (32) per module reduces space and wiring complexity
Ability to generate pulse width and time‑proportion outputs gives flexible control beyond simple discrete ON/OFF
Status display on each channel helps troubleshooting and operational clarity
Fast response times (3 ms status; 10 ms mixed) allow for timely control and monitoring
Good electrical isolation increases reliability and reduces interference risks
Moderate size and weight (~0.20 kg) aid in compact installations
Here are five comparable models in the ADV551 family, with key parameters for comparison:
| Model | Output Channels | Pulse / Time‑Proportion Output | Status Display | Key Differences | Weight (kg) |
|---|---|---|---|---|---|
| ADV551‑P63 | 32 | Yes | Yes | Similar features, perhaps different suffix variant | 0.20 |
| ADV551‑P50 | 32 | Yes | No | No status display; simpler version | 0.20 |
| ADV551‑E63 | 32 | Yes | Yes | Explosion‑proof or enhanced environmental version | ~0.20 |
| ADV561‑P63 | 64 | Yes | Yes | Double channel count; larger module | ~0.30 |
| ADV551‑P10 | 32 | No | Yes | Earlier variant, no pulse/time functionality | 0.20 |
Here are five other modules from Yokogawa that are often used in similar spaces (either digital output or analog etc.):
| Model | Function / Use Case | Key Parameters | Weight (kg) approx. |
|---|---|---|---|
| ADV151‑P63 | Digital Input – 32 channels, status + pushbutton / signal display | 24 V input, 32 channels, status display | ~0.30 |
| AAI143‑S50 | Analog Input – voltage / current channels | 16 channels, various ranges | ~0.40‑0.50 |

Q1: What is the meaning of “P60” suffix in ADV551‑P60?
A1: “P” denotes that this variant supports pulse width and/or time‑proportional outputs; “6” means it includes status indicators (display), and “0” indicates the basic (non explosion‑proof) version.
Q2: How many output channels does ADV551‑P60 provide?
A2: It provides 32 digital output channels.
Q3: What is the rated voltage for outputs?
A3: Nominal operating voltage is 24 V DC.
Q4: What is the maximum load current per channel?
A4: Up to 100 mA per channel at about 26.4 V DC.
Q5: How fast does the module respond when status outputs change?
A5: Status outputs respond in ≤ 3 ms.
Q6: What about mixed outputs (status + pulse / time proportion)?
A6: Mixed mode (status + pulse or time‑proportional) response time is ≤ 10 ms.
Q7: What is the minimal pulse width and greatest duration available for pulse/time‑proportional outputs?
A7: Minimal pulse width is 8 ms, maximum duration is 7200 seconds (i.e. up to 2 hours), with resolution of about 8 ms and up to ~1 ms delay for ON/OFF edges.
Q8: What is the weight and size of the module?
A8: Weight is about 0.20 kg; dimensions approximately 130 mm × 100 mm × 35 mm.
Q9: What level of electrical isolation is provided?
A9: Withstands 2 kV AC for 1 minute between output signals and system; 500 V AC for 1 minute between common terminals (per groups of channels).
Q10: Is this module explosion‑proof or suited for hazardous area installations?
A10: No – the “0” in P60 suffix indicates the basic version, without explosion‑proof certification. For hazardous area use, a variant with appropriate suffix (e.g. “E…” etc.) would be required.
