SMC 5B1-40D Electro-Pneumatic Pressure Regulator

SMC 5B1-40D Electro-Pneumatic Pressure Regulator is a compact electronic regulator that uses a 24 V DC input to control downstream air pressure, delivering a maximum regulated pressure of 130 psi. The device draws 20 mA from the supply, enabling integration with standard automation controllers and control circuits. It is designed to translate an electrical control signal into a regulated pneumatic output, supporting precise pressure management in pneumatic circuits that require electronic control. The 5B1-40D is part of SMC’s family of electro-pneumatic regulators and is suitable for installations where a dedicated 24 VDC interface is used to set and maintain target pressure in automated equipment. This model’s 130 psi ceiling makes it appropriate for applications that need moderate pressure regulation in compact spaces, helping to maintain stable actuator and valve performance in manufacturing and processing automation.
