Product Details General Note About Relays and Inductive Loads High voltage transients may occur when switching inductive loads such as some contactors or solenoid valves. Through the internal contacts, these transients may introduce disturbances which could affect the performance of the instrument.For this type of load it is recommended that a ‘snubber’ is connected across the normally open contact of the relay switching the load. The snubber recommended consists of a 15nF series connected resistor/capacitor (typically 15nF/100Ω). Asnubber will also prolong the life of the relay contacts.A current transformer can be connected directly to the controller to monitor the actual current supplied to an electrical load. A digital (logic) input from a volt free contact can be configured to select Setpoint2, Keylock, Run/Hold, Reset, Alarm Acknowledge or Auto/Manual. The common connection is shared for each of these inputs and is, therefore, not isolated.
Moore News NONFERROUS INDUSTRY:Non-ferrous Industry CapabilityThe sintering method and the Bayer process are currently the main methods for industrial production of alumina.Most of the alumina produced is produced by Bayer process.The Bayer-sintering hybrid method was first created, which greatly improved the total recovery of alumina.With the continuous improvement of production technology, some new production methods such as lime Bayer method and beneficiation Bayer method are continuously applied to production.
