The Model 2300 is a High Resolution, 19-bit, 8-Channel Current Input Network Node that is housed in a compact DIN rail enclosure. It allows integration of up to 8 current output transmitters into the LonWorks distributed digital network. Using the Model 2300 allows multiple sensors to be used over a simple four-wire bus installation. Two wires are used for power, the other are used for digital communication. The communication interface is the FTT-10 transceiver. All connections to the Model 2300 are made via high quality removable terminal blocks. Power into the Model 2300 is reverse voltage protected, individually fused, and finally made available to the sensor terminal blocks. This feature allows simple power distribution to each 4-20 mA transmitter and reduces external wiring. Additionally, the input current sense resistors are individually protected against over- current conditions by a unique circuit. The protection circuit will limit the input current and return an error value to attached network device. The protection circuit will automatically recover when the fault condition is removed and will resume normal measurement.
