MVAJ21T1GB0771B communication module
Technical data of product parameters
MVAJ21T1GB0771B is an auxiliary variable speed relay whose manufacturer has discontinued production. According to source 0, this module is a relay module component, and the general auxiliary relay of the FX series PLC does not have a power-off protection function. In addition, battery backup/latch assist relays can be used in such situations. When the power supply is interrupted, use a lithium battery to maintain the contents of the image registers in RAM or store them in the EEPROM. According to source 3, MVAJ21T1GB0771B is a low voltage auxiliary variable speed relay with a rated voltage of 110/125 volts.
According to Source 1, the module should be operated through the edges of its front panel, frame, or printed circuit board to avoid touching electronic components, printed circuit tracks, or connectors. If you are transferring the module to another person, make sure that you and the other person are at the same electrostatic potential. Handshaking can achieve potential balance.
According to Source 2, wireless communication modules are widely used in vehicle monitoring, remote control, telemetry, small wireless networks, wireless meter reading, access control systems, community paging, industrial data collection systems, wireless tags, identity recognition, non-contact RF smart cards, small wireless data terminals, safety and fire protection systems, wireless remote control systems, biological signal collection, hydrological and meteorological monitoring, and machinery.
In summary, MVAJ21T1GB0771B is a low-voltage auxiliary variable speed relay whose manufacturer has discontinued production. This module is a relay module component. The general auxiliary relay of the FX series PLC does not have a power failure protection function. If it is necessary to maintain the state during a power outage, a battery back-up/latching auxiliary relay can be used. When operating a module, it should be done through the edges of its front plate, frame, or printed circuit board. Wireless communication modules are widely used in various occasions, such as vehicle monitoring, remote control, telemetry, small wireless networks, and so on.
