Foxboro I/A Series Compact 200 16 Slot Horizontal Substrate (31H2C480B4)

Support redundant communication links (with the cooperation of the controller). When the main communication link fails, the backup link will automatically switch to ensure that data is not lost.

（3） Fault diagnosis and maintenance convenience

Status indication:

The front of the substrate is equipped with LED indicator lights, including a "power status light" (main/backup power, green constant light indicates normal, red flashing indicates fault), a "bus status light" (yellow constant light indicates normal, off indicates bus interruption), and a "module fault summary light" (red light indicates any slot module fault), which facilitate quick judgment of the system status;

Module hot plug support:

All 16 slots support "hot swappable" (the module itself needs to have a hot swappable design). When replacing the I/O module, there is no need to disconnect the power supply or communication cable of the substrate. Simply unlock the module buckle to plug and unplug, reducing maintenance downtime;

Fault isolation:

A single slot is equipped with an independent fault isolation circuit. When a certain I/O module fails, the substrate automatically cuts off the abnormal signal between the slot and the bus to prevent the fault from spreading to other modules or higher-level controllers.

（4） Environmental protection and durability

Anti pollution capability: meets the G3 level (harsh) environmental requirements of ISA standard S71.04, can withstand industrial dust, oil and gas, corrosive gases (such as hydrogen sulfide), and the substrate surface is coated with anti-corrosion coating (such as epoxy resin) to extend its service life;

Resistance to vibration and impact:

Vibration protection: Within the frequency range of 5-500Hz, it can withstand a sine vibration of 7.5m/S ² (0.75g), meeting the installation requirements near vibration sources such as pumps and compressors;

Impact protection: capable of withstanding a 15g (half sine wave, duration of 11ms) impact, suitable for the impact environment of industrial equipment transportation and on-site installation;

Temperature adaptability: Operating temperature range -20 ° C to+60 ° C, storage temperature range -40 ° C to+85 ° C, suitable for most industrial scenarios (such as chemical workshops, outdoor control cabinets).
