FBM237 8-channel isolated analog output interface module

FBM237 is an 8-channel isolated analog output interface module belonging to Foxboro's I/A Series Distributed Control System (DCS). It is mainly used to convert digital signals from controllers into standard analog signals to drive on-site actuators, and is widely used in multiple industrial fields due to its high precision and reliability. The detailed information is as follows:

Core Technical Specifications

Parameter	Details
Output Channels	8 independent DC analog output channels, each channel is electrically isolated from other channels and the ground.
Output Signal & Range	The main output is 0 - 20mA DC, and some can reach 0 - 20.4mA DC, which is compatible with most industrial actuators and transmitters.
Precision & Resolution	The precision is ±0.1% of full scale; there are different specifications for resolution, including 12-bit and 13-bit, which can ensure the accuracy of control signals.
Load Capacity	The maximum load capacity can reach 750Ω, and some versions are marked as 500Ω, which can adapt to different on-site wiring and equipment load requirements.
Power Supply	It adopts 24V DC power supply, and the voltage allows a fluctuation range of +5% and -10%. The maximum power consumption is 7W, and the maximum heat dissipation is 5W, with low energy consumption.
Physical Dimensions & Weight	The size is 102mm in height, 45mm in width and 104mm in depth, and the weight is about 284 grams, which is compact and easy to install in the standard rack of the system.
Environmental Adaptability	The operating temperature range is -20°C to +70°C, and the storage temperature can reach -40°C to +85°C. It is suitable for the G3 harsh environment defined in the ISA S71.04 standard and can work normally in an environment with 5% - 95% relative humidity (non-condensing).
