Product Description
The Yokogawa ADV142-P03 is a 16-channel high-voltage digital input module designed for the CENTUM VP Integrated Production Control System. It is intended to interface with 200–240 V AC field signals commonly found in motor control centers, industrial switchgear, and power distribution networks.
The P03 suffix indicates G3-compliant protection against corrosive gases and an extended operating temperature range of –20 to 70 °C, making the module suitable for harsh industrial environments. It provides robust electrical isolation (2 kV AC) between field inputs and system logic, ensuring high reliability and safety.

Technical FAQ
Q: How does ADV142 differ from ADV141?
A: ADV141 handles 100–120 V AC, while ADV142 is rated for 200–240 V AC. Using the wrong voltage can permanently damage the module.
Q: Why is the response time 160 ms, slower than DC modules?
A: AC inputs require rectification and filtering to distinguish true ON/OFF states across a 50/60 Hz sine wave, which naturally slows response compared to 24 V DC modules.
Q: Does this module require a specific terminal block?
A: Yes, high-voltage rated pressure-clamp or compatible cables are required to maintain creepage distances and operator safety.
