YOKOGAWA NFAF135-S00 Frequency Input Module

Description

The YOKOGAWA NFAF135-S00 Frequency Input Module is a specialized component for industrial control systems, with technical specifications and features aligned with the related AAP135-S00 Pulse Input Module from the YOKOGAWA CENTUM VP series Distributed Control System (DCS). It is an 8-channel module with channel-to-channel electrical isolation, such as optocoupler isolation, providing strong anti-interference performance for reliable operation in industrial environments. The module supports a pulse counting range of 0 to 10 kilohertz, and is designed to accept multiple input signal types, including thermocouples (types J, K, T, E, R, S, B), resistance temperature detectors (PT100, Cu100), voltage signals (0-10V, 1-5V), and current signals (4-20mA). As a standard configuration marked by the -S suffix, it also offers optional configurations including compliance with ISA standard G3 and an operating temperature range of -20 to 70 degrees Celsius. The module is compatible with the ATI3A-00 KS cable interface adapter, and can be integrated into dual redundant configurations to enhance system stability. It is engineered to simultaneously collect multi-channel signals, making it suitable for pulse and frequency monitoring applications in process control scenarios.
