Technical Specifications Module Type: HART‑capable Analog Input Module Channel Quantity: 8 input channels Input Signal: 4‑20 mA DC with HART superimposed digital signal Channel Isolation: Per‑channel galvanic isolation Communication: Redundant I/A fieldbus, supports HART protocol Operating Power: 24 VDC Operating Temperature: 0 °C to +60 °C Storage Temperature: ‑40 °C to +85 °C Relative Humidity: 5%‑95%, non‑condensing Mounting: DIN‑rail baseplate installation Certifications: CE, HART protocol compliance certification
Functional Features Eight‑channel isolated 4‑20mA analog input with HART signal transparent transmission. Simultaneously acquires process analog value and HART transmitter diagnostic data. Built‑in channel fault diagnosis for loop open‑circuit and short‑circuit abnormal condition. Redundant fieldbus communication ensures reliable data transmission. Hot‑swappable module design for convenient on‑site maintenance replacement.
Application Scenarios Widely used in petrochemical and chemical industry DCS control projects. Cooperates with HART intelligent pressure, flow and liquid‑level transmitters, completes process variable collection and on‑line diagnosis management of field intelligent instruments.
Structural Characteristics Compact 200‑series module housing for baseplate mounting. Gold‑plated bottom connector for connection with DIN‑rail baseplate. Front‑panel LED indicators for power, bus communication and channel fault status. Matches dedicated termination assembly for HART field transmitter wiring conversion.
Working Principle HART field transmitter outputs 4‑20mA analog signal superimposed with HART digital signal. Signal is transmitted to FBM214 module through termination assembly. Module separates analog process value and HART digital diagnostic information.
Installation Requirements Install supporting baseplate on standard 35 mm DIN‑rail inside control cabinet. Insert FBM214 onto baseplate and lock mechanical buckle. Connect HART field transmitter wiring to matched termination assembly terminals. Complete redundant fieldbus cable connection.
