Foxboro P0961CA Fiber Optic LAN Module

200 Series Substrate Mounting

Most 200 series baseboards are available in three basic mounting configurations –

horizontal DIN rail mount),vertical DIN rail mount, or horizontal or vertical DIN rail mount,

but the baseboards themselves must be orientated horizontally.

Any of these mounting configurations can be used inside the cabinet,

outside the cabinet, or mounted on secure DIN rails.

The combination of a pair of modules provides redundancy at the fieldbus

module (FBM) level. In this configuration, one FBM233 is the master and the

other is the tracking module. Input points on the control station are updated

from device input points received on the network connected to the master.

Device output points (depending on the I/O driver) are written by both the

master and the trace module.

If the I/O driver detects a problem (e.g. any device loses its heartbeat), a role

switch is automatically performed, or the user can switch roles at any time via

the SMDH.

Fieldbus Communication Modules (FCMs) are fibre optic communication extenders that allow

200 Series fieldbus modules to be remotely mounted near plant processes.

FCM2F2 (RH914YZ), FCM2F4 (RH917JA) and FCM2F10 (RH916TQ)

Three models are available with nominal maximum substrate-to-substrate fibre optic

cabling distances: up to 2 km (1.24 mi), 4 km (2.48 mi) and 10 km (6.21 mi) respectively.

FCMs are mounted in pairs on standard baseboards for redundancy.

Non-redundant configurations require only a single FCM.

Fibre optic cabling is unaffected by electrical noise (EMI, RFI and lightning)

and is a versatile and highly reliable means of extending signal communications.

It can be used in areas containing equipment such as rotating machinery, arc welders, etc.

It can also be installed in cable bridges containing high voltage power lines,or in outdoor

areas exposed to lightning hazards. or outdoor areas exposed to lightning hazards.

Its electrical isolation features protect against voltage differences and ground loops.

 supports FCP280/FCP270. FDC280. and FCM100Et baseboards:

– Connection for optional GPS time strobe.

All non-FDC280 module time strobe connections require a splitter/splitter.

direct connections are supported on the FDC280 baseboard.

 All baseboards are supported except the FDC280 baseboard (RH101KF):

– Connection to 2 Mbps modular fieldbus for standard fieldbus modules or 268 Kbps fieldbus for 100 series FBMs

– Splitter/terminal modules for A/B fieldbuses

– Backwards compatible with existing I/O subsystems, allowing for future expansion

No additional interface hardware required

 Primary and secondary 24 VDC power supplies and communication connections

 Dedicated keying position for individual CP-type modules (e.g. FCP280. FDC280 or FCM/FBM),

depending on the substrate type

 Passive backplane for increased system reliability.
