ABB FSM4000 S4 Signal Converter Power Supply Unit

ABB FSM4000-S4 Signal Converter Power Supply Unit is the external converter for ABB's FSM4000 electromagnetic flowmeter family, delivering the required power and signal conditioning to the FSM4000-S4 transmitter. It accepts a wide-range mains input of 85-253 V AC at 50/60 Hz and draws less than 45 VA, enabling flexible installation across different regions. The unit's coils and signal circuit can be connected with ABB sensors only, reinforcing system integrity within ABB's measurement platform. It supports a pulse output and passive HART communication on the signal line, allowing basic integration with field devices and monitoring equipment without active digital power. It is identified as FSM4000-S4, with order number 0002238521 / Y001, and is designed to be used with the FSM4000-S4 transmitter assembly within industrial process environments. This external converter is a component of ABB's Measurement & Analytics FSM4000 family, engineered for robust performance in demanding applications where accurate flow measurement and reliable sensor interfacing are required.
