GE IS220PPRFH1A | I/O Pack | PPRFH1A | Mark VI Turbine Control System.Mark VI General Electric module IS220PPRFH1A is labeled a Profibus Master GatewayAnalog I/O Pack and works with the IS200PIDG1A accessory board. This model was rated to operate in hazardous and non-hazardous locations.Model number IS220PPRFH1A is described within the Mark VI series produced by General Electric as a PROFIBUS Master Gateway Module. While this model was designed to be used in the Mark VI series, it can also be used in the Mark VIe and Mark VIeS series. The PPRF model is considered an analog output pack and is often used with the IS200SPIDG1A accessory ID board. Together the I/O pack and the terminal board were rated and approved for hazardous and non-hazardous locations. www.plc-module.com  When the IS220PPRFH1A model is being used, there are electrical specifications that must be followed so as to eliminate potential property damage or some cases, personal injury. There are two specifications, labeled voltage and current. The power supply voltage has a range of 27.4 to 28.6 VDC, with the nominal voltage supply being 28.0 VDC. The power supply current used by the PPRF pack is a maximum of 0.18 ADC. There is also a specific temperature range the PPRF model must be used in; this temperature range is -4 to 131°F or -20 to 55°C.
