FOXBORO FBM237

FOXBORO FBM237 is a channel isolation output interface module produced by Foxboro,mainly used in industrial automation control systems.The following is a detailed introduction to the module:

I.Product Overview

The FBM237 module provides isolated 0 to 20mA DC analog output channels,each of which is electrically isolated to prevent interference and fault propagation between circuits.The module is ruggedly designed for use in a variety of environments,especially G3-level(harsh)environments.It can also be used as a single unit or redundant pair to improve system reliability and stability.

II.Main Features

Eight output channels:The FBM237 module contains eight isolated 0 to 20mA DC analog output channels,each of which can independently drive an external load.

Electrical isolation:Each output channel is insulated from other channels and ground to ensure that interference and faults between circuits do not propagate.

Redundancy function:The module can be used as a redundant pair.When a failure is detected in one of the modules,its output will be driven to 0mA,and the corresponding channel in the good module will automatically continue to provide appropriate current.

Rugged design:The FBM237 module features a rugged extruded aluminum housing that provides physical protection for the electronic circuitry.The cabinet is specially designed to protect the FBM installation in all types of environments,even in harsh environments defined by ISA standard S71.04.

Communication capability:Communication with the control station is via an optionally redundant Ethernet fieldbus,ensuring reliable and stable data transmission.

III.Technical specifications

Output range:The output range for each channel is 0 to 20.4mA dc.

Output load:Maximum 750Ω.

Output processing delay:Maximum 30ms.

Resolution:13 bits.

Power requirements:Input voltage range is 24V dc+5%,-10%,power consumption is maximum 7W,and heat dissipation is maximum 5W.

Working environment:temperature range is-20 to+70°C(-4 to+158°F),relative humidity is 5 to 95%(non-condensing),altitude is-300 to+3,000 meters(-1,000 to+10,000 feet).
