Product Description
The ADC32-S1 is a high-density safety-rated discrete output module designed for the Yokogawa Electric Corporation ProSafe-RS Safety Instrumented System (SIS) platform.
This module provides 32 independent relay contact outputs for safety-critical field actuation, including:
-
Emergency shutdown (ESD) final elements
-
Fire & gas (F&G) safety responses
-
Solenoid valve control
-
Motor starter interlock triggering
The ADC32-S1 is optimized for high availability safety architectures, using mechanical relay contacts to provide true galvanic isolation between safety logic circuits and field-side power systems. Front-panel diagnostic LEDs allow maintenance personnel to instantly verify channel status during commissioning or troubleshooting.

Operational Applications
Emergency Shutdown Systems (ESD)
Controls safety valves, shutdown actuators, and process isolation devices.
Fire & Gas Protection Systems
Triggers alarm annunciators and protective field responses.
Sequence of Events (SOE) Recording
Provides reliable safety event signaling for plant auditing and compliance monitoring.
Control Room Signaling
Drives large arrays of indicator lamps or safety status panels.
The relay-based architecture is especially suitable for safety loops requiring dry contact closure logic rather than sourced voltage outputs.
Frequently Asked Questions
Is the ADC32-S1 suitable for high-frequency switching?
No. Since the module uses mechanical relays, it is designed for safety logic and interlock switching rather than high-speed PWM or pulse modulation. For high-speed control, transistor-based output modules are recommended.
Does this module support both AC and DC loads?
Yes. The relay contacts support both AC and DC switching. However, users must ensure load current and voltage remain within specified inductive and resistive limits to prevent contact wear or pitting.
Is this module suitable for safety-critical loops?
Yes. The ADC32-S1 is specifically engineered for safety integrity applications within ProSafe-RS SIS architectures.
