Foxboro FBM219 Mixed Discrete I/O Interface Fieldbus Module

Technical Specifications

Model:FBM219(P0916RH / P0917LH)

Brand:Foxboro

System compatibility:I/A Series DCS Compact‑200‑series fieldbus I/O subsystem,works with FCP/FCM controller,supports single‑module operation or redundant hot‑standby pair with second FBM219,matched with Compact‑200‑series baseplate,redundant adapter RH101AZ and corresponding termination assembly

Function:Compact‑form‑factor group‑isolated mixed discrete input/output fieldbus module,24 discrete input channels acquire contact or voltage‑monitor status from field switches,sensors and valve feedback;8 discrete output channels drive solenoid valves,indicators and auxiliary relays,supports multiple signal voltage ranges dependent on termination assembly,configurable input debounce filter time,fail‑safe output state setting,on‑board Sequence‑of‑Events(SOE) timestamp function,local ladder logic processing capability

Installation:Compact‑200‑series baseplate‑mount installation;for redundant configuration,two FBM219 occupy adjacent baseplate slots with redundant adapter RH101AZ,share one common termination assembly

I/O channel:

‑Discrete Input:24 channels,supported signal:15‑60V DC,120V AC/125V DC,240V AC

‑Discrete Output:8 channels,signal range depends on matched termination assembly

‑Group‑wise galvanic isolation between field group and module logic ground,non‑channel‑to‑channel isolation

Circuit feature:Opto‑coupler isolation implemented on termination assembly side,configurable input filter time,SOE timestamp resolution 1ms,channel over‑current limiting protection,open‑circuit and short‑circuit channel fault diagnosis

Feature:Support hot‑swap online replacement without subsystem power‑off,redundant 2Mbps fieldbus communication with FCP/FCM controller,hardware‑level hot‑standby redundancy available,compact mechanical outline for cabinet space‑saving deployment,group‑isolated design

Diagnostic:Front‑panel multi‑color LED indicators for power,fieldbus communication and per‑channel status,SOE timestamp data and channel fault status passed to DCS system

Power supply:24VDC via Compact‑200‑series baseplate backplane

Built‑in function

FBM219 mixed discrete I/O module collects field switch,valve feedback and equipment status signals,and outputs drive signals to field solenoids and auxiliary executing devices for Foxboro I/A‑Series DCS system. It adopts group‑isolation architecture. Built‑in SOE high‑precision time‑stamping supports accident‑sequence analysis. It can run as single‑point acquisition‑output or form hot‑standby redundant‑pair with another FBM219. Hot‑swap supports online module replacement without system shutdown,widely applied for interlock logic,valve‑motor status monitoring and discrete‑control‑loop maintenance in petrochemical,chemical and power‑plant facilities.

Product Brief

FBM219(P0916RH/P0917LH) belongs to Foxboro I/A Series legacy DCS Compact‑200‑series mixed‑discrete‑I/O spare‑part family,obsolete original compact‑form‑factor 24DI‑8DO discrete‑input‑output module component. Must match with Compact‑200‑series dedicated baseplate and matched termination assembly. Widely used for original Foxboro DCS equipment maintenance and renovation. ESD anti‑static protection shall be followed during installation.
