Description
FCM10E modules have a compact design, with arugged extruded aluminum exterior for physicalprotection of the circuits. Up to 30 FCM10E pairs canbe connected to the Ethernet trunk Fieldbus.Enclosures specially designed for mounting of DINrail mounted FBM equipment provide various levels ofenvironmental protection for the FieldbusCommunications Modules, up to harsh environmentsper ISA Standard S71.04.
Analog input/output interfaces are generally used to sense signals generated by sensors. These interfaces can be used to measure flow, temperature, and pressure, as well as to control voltage or current output devices. The typical ranges of these interfaces are -10~+10V, 0~+10V, 4~20mA, or 10~50mA.
Some manufacturers design special analog interfaces on PLCs, which can receive low-level signals such as RTDs, thermocouples, etc. Generally speaking, this type of interface module can be used to receive different types of thermocouple or RTD mixed signals on the same module.
Special function input/output
When selecting a PLC, users may face some special types of I/O limitations that cannot be achieved using standard I/O (such as positioning, fast input, frequency, etc.). At this point, users should consider whether the supply and marketing manufacturers provide special modules that help minimize control effects. Some special interface modules can handle a portion of on-site data themselves, freeing the CPU from time-consuming task processing.
