Product Description
The ADC16 is a high-density digital input module designed for the Yokogawa Electric Corporation CENTUM VP control environment, with compatibility across legacy and modern CENTUM platforms.
It is engineered to capture binary (ON/OFF) states from field equipment such as:
-
Limit switches
-
Pushbuttons
-
Auxiliary relay contacts
-
Valve position feedback contacts
The ADC16 converts mechanical contact status into logic signals for the DCS, enabling precise event monitoring and alarm handling.
Each channel features individual optocoupler isolation, protecting the system backplane from electrical noise, voltage spikes, and ground loop interference. Its dry-contact architecture is optimized for voltage-free sensing, typically using a 24 V DC loop for state detection.

Integration with the CENTUM engineering suite enables accurate event time-stamping, alarm generation, and sequence-of-events recording.
Frequently Asked Questions
Does the ADC16 require external power for contact sensing?
Yes. While the module logic is powered from the rack, a 24 V DC field supply is typically required to energize the dry contact loop for state detection.
Can the ADC16 be hot-swapped?
Yes. In CENTUM VP and compatible architectures, online module replacement is supported when system configuration and plant safety procedures are properly followed.
