Rack Mountable 0.5 inch POE NTP Clock
$189.99The TM160 POE clock is a low profile clock based on the same hardware and software as our other NTP digital clock displays. The bright red digits are 0.5 inches tall. It is installed in the same case as any of our time servers, making it an ideal solution for a rack mount companion to those products. It can be mounted using the same 1U rack mount face plates that the TM1000, the TM2000, or the TM2500 use. Mount a single clock using the 760-022-000 plate, or mount a time server and a clock in a 1U space using the 760-023-000 dual rack mount plate. Its small size also makes it ideal as an interface to a campus wide bell system. It has the same relay output that our other displays have and all of the same versatility for alarm event setting through its web interface or using TM-Manager. The rack mount plate and relay connector is sold separately.
