Product Description
The SDV144-S53 S2 is a 16-channel safety digital input module designed for the Yokogawa ProSafe-RS Safety Instrumented System (SIS). It provides robust galvanic isolation between field devices and the safety controller, ensuring signal integrity in harsh industrial environments.
This module features ISA Standard G3 conformal coating for corrosion resistance and an extended operating temperature range of -20 to 70 °C, making it suitable for remote or outdoor installations. The S2 hardware revision incorporates refined internal components for enhanced thermal management while maintaining full SIL3 safety compliance.
The SDV144-S53 S2 supports pressure clamp terminals or MIL cables and ensures high-speed safety logic execution with a maximum 40 ms response time.

Frequently Asked Questions
What does the “3” in the S53 suffix signify?
The “3” indicates that the module is equipped with G3-compliant conformal coating and rated for high-temperature operation (-20 to 70 °C), making it more durable than standard indoor-only variants.
Can this module be used in explosive atmospheres?
The SDV144-S53 S2 is intended for non-explosion-proof areas. For hazardous area installations, Zener barriers or galvanic isolators must be used to meet intrinsic safety requirements.
