Technical Specifications Module Type: Discrete Digital Input Module Channel Quantity: 16 digital input channels Input Signal: Dry‑contact / DC voltage discrete input Channel Isolation: Per‑channel galvanic isolation Communication Interface: Redundant I/A fieldbus 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 industrial digital I/O module compliance
Functional Features Sixteen‑channel isolated digital switch‑value signal acquisition. Configurable input filter time suppresses field signal jitter interference. Built‑in channel fault diagnosis function reports circuit abnormal status. Redundant fieldbus communication supports automatic link switching. Hot‑swappable module structure for convenient on‑site maintenance replacement.
Application Scenarios Applied in petrochemical, chemical and power‑industry DCS control system. Collects field valve position feedback, equipment running status, safety interlock switch discrete signals, provides status data for system interlock logic and equipment monitoring.
Structural Characteristics Compact 200‑series module housing, hardware assembly part number P0916JS. Gold‑plated bottom connector for electrical connection with DIN‑rail baseplate. Front‑panel LED status indicators for power, bus communication and channel alarm. Works together with matched termination assembly for field signal wiring conversion.
Working Principle Field discrete switch‑value signal passes through termination assembly to FBM207B P0916JS module. After filter and isolation processing, module identifies each channel on‑off status, transmits digital status data and diagnostic information to DCS field control processor via redundant fieldbus.
Installation Requirements Mount matched baseplate on standard 35 mm DIN‑rail inside control cabinet. Insert FBM207B P0916JS onto baseplate and lock mechanical buckle. Complete field switch‑signal wiring on corresponding termination assembly terminals. Connect redundant fieldbus cable between baseplate and control processor. Set input filter parameters in DCS configuration software after power‑on.
