YOKOGAWA PSCCM22AAN Critical Control Module

Description

The YOKOGAWA PSCCM22AAN Critical Control Module is a specialized component designed for safety instrumented systems (SIS) and industrial automation applications, engineered to execute safety logic and ensure secure operation of industrial processes. Equipped with a 32-bit RISC microprocessor, it delivers reliable performance, paired with 8MB RAM and 2MB Flash memory to support safety logic operations and data storage. It features dual communication interfaces: Ethernet and RS-232, and is compatible with Modbus protocol for seamless integration with third-party devices, while some variants also support HART protocol for smart sensor diagnostics. Powered by 24VDC (with ±10% tolerance and reverse polarity protection in some models), it operates in a temperature range of -40 degrees Celsius to 85 degrees Celsius, with a humidity range of 5% to 95% non-condensing, making it suitable for harsh industrial environments. The module meets IEC 61508 standards and supports SIL 2 safety rating, with built-in diagnostic functions and redundant configuration capability to enhance system reliability. Measuring 110mm x 60mm x 25mm and weighing 200g, it has a protection rating of up to IP65, and some variants support up to 8 independent PID control loops with 4-20mA analog input/output signals.
