RADIODETECTION SI220 Smart InterrupterProduct infoThe SI220 is a high performance Smart Interrupter for monitoring the effectiveness of Cathodic Protection systems. It is a solid state device for use by Corrosion Technicians to enable the interruption of the CP current thereby allowing the integrity of the pipeline coating to be evaluated without disturbing the pipeline as part of the routine maintenance of cathodically protected pipes. With the ability to switch currents up to 100 Amps at 220V peak (155V rms) and the capability to synchronise up to 8 units using a GPS time stamping system (supplied as standard) the SI220 can be used to monitor a variety of CP systems and the effect of multiple CP sources. The product comes as a 2 part kit comprising a base unit controller which drives the 100A switching capability booster pack. Lightweight and modular the product is designed for the typical kinds of field use and environment that the CP technician will come across.Key features• High voltage and current switching capability - for todays CP systems; longer pipes in difficult conditions• Ability to synchronize multiple units for evaluation of complex networks• Easy to use with simple menu operation and powerful control features• Advanced safety features including transient and overvoltage protection and cool running even at elevated external ambient temperatures• Full microprocessor controlled, automatically stores the last ten used setups and stores up to 10 Waveforms.• On/Off ranges between 0 to 100 seconds• GPS synchronization as standard; permits synchronization of any number of interrupters remote from each other and permits 24hr timer operation.• Can generate 4H &8Hz for compatibility with Radiodetection Precision Pipe Locators.
