The ADM52C-2 is a connector-type digital output module for Yokogawa RIO configurations. It provides 32 output points using transistor-contact outputs and supports status output, pulse-type output, pulse-width output and time-proportional ON/OFF functions. The “-2” suffix specifies hold action during online maintenance, with the hold behavior applying in status output mode.

ADM52C-2 Technical Profile
01 / Channel Structure
ADM52C is the 32-point connector-type member of the ADM5xC digital output family. ADM52C-2 therefore provides 32 output points within the same module architecture, making it suitable where a higher point count is required without moving to the 16-point ADM51C configuration.
OUTPUT POINTS32
02 / Output Technology
The output signal is specified as a transistor contact. The contact rating is suitable for resistive or inductive loads up to 30 V DC and 100 mA or less. When selecting a field load, the external circuit should remain within the specified contact rating.

MODEL RELATIONSHIP
What the ADM52C-2 Variant Changes
The ADM52C family shares the same 32-point connector-type output architecture. The suffix is important when evaluating behavior during online maintenance.
ADM52C
Base 32-Point Architecture
The ADM52C family provides 32 transistor-contact output points, connector-based field connection, and the common-minus-side arrangement every 16 points.
ADM52C-2
Hold Action During Online Maintenance
The “-2” suffix specifies hold action during online maintenance. According to the module specification, the output hold action of ADM52C-2 is effective in status output mode.
ADM52C-2 sits on the digital-output side of the Yokogawa RIO architecture. The module translates control-side discrete states into transistor-contact outputs for connected field circuits.

Output Configuration Consideration
The ADM52C-2 is a transistor-contact output module rather than a conventional relay-output module. Load selection should therefore be checked against the specified 30 V DC / 100 mA maximum contact rating. For applications using inductive loads, the external circuit design should account for the electrical characteristics of the connected load.

Need ADM52C-2 for a Replacement or System Project?
Send us the part number, quantity, destination, required date and machine/system details. Our sales team can help check the requested configuration and arrange the next step.
01 — When replacing an ADM52C-2, why does the “-2” suffix matter?
The suffix defines the online-maintenance behavior. The ADM52C-2 uses hold action during online maintenance, and the specified hold action is effective in status output mode. Therefore, a replacement assessment should compare the complete suffix rather than treating ADM52C and ADM52C-2 as behaviorally identical variants.
02 — Can ADM52C-2 replace a 16-point ADM51C when the control logic needs more output points?
ADM51C and ADM52C belong to the same digital-output family, but their point counts differ: ADM51C provides 16 points while ADM52C provides 32 points. ADM52C-2 is therefore the 32-point configuration. A replacement should still be checked against the existing wiring, channel assignment and system configuration before installation.
03 — Is ADM52C-2 suitable when the field circuit uses an inductive load?
The specified contact rating covers both resistive and inductive loads at 30 V DC and 100 mA or less. This rating is the boundary for selecting the connected circuit. The actual field device and its transient characteristics should be evaluated before connecting the output.
04 — What should be checked when an existing ADM52C-2 installation needs a cable replacement?
ADM52C is the connector-type version of the 32-point output architecture and uses KS9 or KS10 cable connection. The cable arrangement should therefore be matched to the existing connector configuration and field termination before ordering a replacement cable or changing the installation.
05 — Does ADM52C-2 support pulse-based control as well as ordinary ON/OFF output?
Yes. The ADM52C family supports status output, pulse-type output, one-shot pulse-width output and time-proportional ON/OFF functions. For pulse-width operation, the specified setting range is 0.1 to 7200 seconds with 20 ms resolution. The exact mode should be matched to the control strategy used by the host system.
