SMEs as an open distributed control system to maintain the best performance of the system at the same low cost. PlantScape Vista / HC900 to meet a variety of process automation equipment control applications require Honeywell temperature module is flexible, reliable sized distributed control system, is currently used as a substitute for all PLC programmable logic controller on the market the ideal solution for every device process control systems. 1. Open system architecture 2. Flexible and reliable integrated controller 3. The spot color LCD operator interface 4. Easy to use and fully functional system configuration tools of two-wire advantages: 1, less susceptible to parasitic thermocouples and pressure drop along the wire resistance and temperature drift, can be used very cheap finer wire; can save a lot of cable and installation costs; 2, when the current source output resistance is large enough inlet temperature module magnetic field sensor coupled to the voltage of the wire loop will not have a significant impact, because the current source of interference caused by small, usually using twisted pair can reduce interference; shield three wire and four-wire shielded cable must be used STT25H temperature module, shielded cable should be properly grounded. 3, capacitive interference can cause the receiver to the resistance of the error, for 4 ~ 20mA two-wire loop, the receiver resistance typically 250Ω (sampling Uout = 1 ~ 5V) that resistance small enough to produce significant errors, therefore temperature module You can allowed wire length longer than the voltage telemetry system; 4, each time a single display device or recording device can be connected to the exchange wire length ranging between different channels, not because of the length of the wire caused by unequal accuracy The difference, to achieve decentralized collection, decentralized capture advantage is: decentralized collection, centralized control .... 5, 4mA to zero level, so that the judge open and short circuit or sensor damage (0mA state) is very convenient. 6, two-wire output port is easy additional twelve lightning protection and surge device, is conducive to safe mine explosion.
