The Yokogawa CP451-51 S2 is a Signal Conditioner from the UTAdvanced series of DIN-rail mounted instruments. It is specifically designed as a Pulse (Frequency) to Analog Signal Converter.
Its primary function is to accept a pulse or frequency input signal from a field device (such as a turbine flowmeter, vortex flowmeter, or digital tachometer) and convert it into a standardized 4 to 20 mA DC analog output signal. This allows pulse-generating sensors to be easily integrated into process control systems, PLCs, or DCSs that expect a standard analog input.

The Allen Bradley 64676-72 RFUSE is a reliable circuit protection device designed for industrial control systems. It offers robust overcurrent protection and is suitable for various applications in manufacturing and automation environments.
