Frequently Asked Questions about 169PLUS-120N-125VDC
What is the 169PLUS-120N-125VDC?
The 169PLUS-120N-125VDC is a Motor Management Relay produced by General Electric Multilin. It is intended for use with three phase medium to large motors and provides elements designed to protect, control, and monitor the motor system. This particular unit has 120 ohm nickel RTD and a control power of 125 V DC.
What RTD inputs does the 169PLUS-120N-125VDC have?
The 169PLUS-120N-125VDC, and other relays in the GE Multilin 169 Plus family of motor management relays have a variety of input options. The 169 Multilin relay model has 6 stator RTDS and 2 additional after those six. In contrast, the 169 Plus relays, such as a 169PLUS-120N-125VDC, has four additional RTDS after those six.
Are mounting accessories provided for the 169PLUS-120N-125VDC Multilin motor management 169 Plus relay?
GE Multilin 169 and 169 Plus motor management relays such as the 169PLUS-120N-125VDC have the ability to be mounted with four mounting holes included on the mounting panel. Included with the relay as purchased from Multilin are four mounting screws (10-32 x 3/8 inch) and four washers. The 169 series of relays are built with internal shielding in order to reduce the amount of interference or noise pickup that the relay experiences during operation. Regardless, it is beneficial to secure the relay in a location separate from magnetic fields or from high current conductors to further eliminate the occurrence of interference. The terminal blocks located at the rear panel of the 169PLUS-120N-125VDC are beneficial to establish connections when necessary. The 169PLUS-120N-125VDC has analog current output terminals that have the ability to be programmed to better tailor a relay to the motor management application. The relays also have a RS 422 Serial port (if Plus model). The 169 Plus relays have four sets of relay contacts (NO/NC). For the purpose of comparison, the 169 model only has two sets of relay contacts.
