The Netbell-Ultra is housed in a Din-rail mountable enclosure. There are 2 relay outputs (1-Form-A relays 110/220@10A) with removable terminal block connector that provides quick connect/disconnect capability simplifying installation, allows you to control up to 2 bells/buzzer and other timed signal equipment. Each device can be connected at 500 feet away from the controller with 16AWG cable (250ft/18AWG) with a suitable power source. With the digital inputs you can wire a push switch for ringing bells manually.

It's ready to go out of the box, and you need only connect the unit to power 12VDC or POE and network with the provided cable; it can be connected anywhere on the network and does not require a direct connection to a PC.
