Product Description
The SAI143-H03 is a high-integrity analog input module engineered for the Yokogawa ProSafe-RS Safety Instrumented System (SIS). Designed to meet SIL 3 safety standards, this module provides 16 isolated 4–20 mA channels for reliable safety loop monitoring. The H03 variant features HART digital communication and an ISA Standard G3 conformal coating, ensuring durable performance even in corrosive and harsh industrial environments.
Key Features
-
SIS Ready: Built for safety-critical applications such as Emergency Shutdown Systems (ESD) and Fire & Gas (F&G) loops
-
HART Digital Integration: Simultaneously transmits analog signals and device diagnostics from smart transmitters
-
G3 Environmental Protection: Corrosion-resistant coating for operation in harsh environments (-20°C to +70°C)
-
Galvanic Isolation: 16 fully isolated channels prevent ground loops and protect the safety system backplane
-
Redundancy Support: Compatible with dual-redundant configurations for uninterrupted safety loop operation
