Product Precautions
- Yokogawa ADV161-P50 S2 captures dense contact and pushbutton signals while retaining separate field-common groups for the connected circuits.
Input density: 64 channels at 24 V DC
Field grouping: 16 channels per common
Pushbutton timing: At least 20 ms ON; up to 25 Hz
Field grouping: 16 channels per common
Pushbutton timing: At least 20 ms ON; up to 25 Hz
The 64 inputs are divided into common groups of 16 channels. Input circuits can use sink or source signals, but all inputs on the module must follow the same polarity arrangement. The field-common map must therefore be checked separately from the physical connector grouping.
The -P execution supports pushbutton inputs. A valid pushbutton event requires at least 20 ms ON time and a maximum switching frequency of 25 Hz; the ordinary input response rating alone is insufficient for evaluating a short pulse.
MIL connector wiring or the applicable AKB337 cable connects the field circuits. Cable insulation can impose a lower withstand limit than the module itself, so the installed termination and cable arrangement must be included in the electrical assessment.

The original technical excerpt applicable to Yokogawa ADV161-P50 S2 covers ADV161 ratings, wiring considerations and suffix selection. PDF · 2 pages.ADV161-P50 S2 Installation & Verification Guide
Apter Power installation and verification guide covering common-group wiring, polarity, input levels and pushbutton point tests. PDF · 5 pages.
Original manufacturer pages retain their technical context. Use the Apter Power guide with the applicable manufacturer instructions and approved installation design.
System and supply context: ADV161-P50 is a CENTUM digital-input execution; S2 identifies the offered hardware series.
Application scope: Use it for compatible 24 V contacts and pushbutton signals with correct common grouping and event timing.
Application scope: Use it for compatible 24 V contacts and pushbutton signals with correct common grouping and event timing.
Operator pushbuttons
Capture pushbutton inputs that meet the specified ON time and repetition limit.Interlock status
Acquire discrete permissive and interlock contacts in the configured logic.Dense field inputs
Bring 64 points to the station through the applicable cable arrangement.Grouped circuits
Separate field commons in 16-channel groups while retaining one polarity scheme.
Prepare Yokogawa ADV161-P50 S2 for its configured installation using these checks.
Common groups
Use four groups of 16 channels, not two groups of 32.
Polarity
Keep the same sink/source scheme across the module.
Input level
Do not exceed 30 V DC at an input.
Pulse duration
Check 20 ms minimum pushbutton ON time.
Cable insulation
Apply the installed cable withstand limit.
Point testing
Test every assigned input and its application action.

Technical notes
Signal and interface: ON recognition requires 20–26.4 V DC and OFF is no more than 5 V DC. The input current is 2.5 mA ±20% per channel.
Installation boundary: All input channels must use the same sink/source polarity arrangement. Dedicated cable withstand requirements can reduce the installation insulation limit.
Technical basis: Yokogawa Digital I/O Modules GS33J60F70-01EN, 5th Edition. ADV161-P50 electrical data and the pushbutton-input suffix apply; S2 remains the offered hardware marking and is not a separate electrical rating.
FAQ View All FAQ
-
How are the commons grouped on ADV161-P50 S2?Each common serves 16 channels, giving four common groups across the 64 inputs.
-
Can ADV161-P50 S2 mix sinking and sourcing signals on one module?No. The module supports either arrangement, but the polarity must be the same for all its inputs.
-
What pulse duration can ADV161-P50 S2 accept as a pushbutton event?The pushbutton input must remain ON for at least 20 ms and must not exceed 25 Hz.
-
Which voltage levels distinguish ON and OFF for ADV161-P50 S2?ON is 20–26.4 V DC; OFF is 5 V DC or less. Check these values at the input terminals.
-
How much field current does one input of ADV161-P50 S2 draw?The input current is 2.5 mA ±20% per channel at the specified input conditions.
-
Why can the cable reduce the insulation rating of ADV161-P50 S2?The module input-to-system withstand rating is 2 kV AC for one minute, but the applicable dedicated cable can impose a 500 V AC limit on the installed connection.
-
Does the 8 ms response of ADV161-P50 S2 permit an 8 ms pushbutton pulse?No. The module response and the pushbutton minimum ON time are separate specifications; the latter remains 20 ms.
-
What should a point test demonstrate on ADV161-P50 S2?Apply ON and OFF levels to each assigned channel, verify the correct CENTUM point and exercise the configured pushbutton behavior without cross-activating adjacent inputs.
