GE PQMII-T20 Switching Input Module

Technical data of product parameters

The GE PQMII-T20 Switch Input Module is a component of the PQM II meter manufactured by GE Multilin, which provides accurate and reliable three-phase power metering with an optional Ethernet and fiber communications module [0]. The PQM II meter is designed on the latest industry specifications and comes in a small and modern package. The Switch Input Module is a part of the PQM II meter that allows the user to assign a numeric value which corresponds to the 4 mA end of the 4 to 20 mA signal range or the 0 mA end of the 0 to 1 mA signal range

The Switch Input Module operates in conjunction with the Analog Input (Optional) and Analog Outputs components of the PQMII meter The Analog Input (Optional) component allows the user to multiplex two analog input signals to the PQMII, while the Analog Outputs component gives the PQMII eight analog outputs The Switch Input Module allows the user to choose which analog input setpoints to use and assign numeric values to the output signal range.

There are several messages that the user can access with the Switch Input Module, such as the “ANALOG IN MAIN/ALT SELECT RELAY” message, which allows the user to select the output relay that is to be used to multiplex two analog input signals to the PQMII There is also the “SWITCH A(D) TIME DELAY” message, which allows the user to enter the required time delay for a switch input function assigned to “Alarm”, “Aux1”, “Aux2”, or “Aux3”

There are a few precautions that the user should take when using the Switch Input Module. It is important that the serial master and PQMII are both at the same ground potential, which is accomplished by joining the RS485 ground terminal Additionally, if the user needs to test the complete switchgear for dielectric strength with the PQMII installed, they should note that the PQMII is rated for 1500 V AC isolation between relay contacts, CT inputs, VT inputs, control power inputs, and Safety Ground Terminal 6
