Outputs are shared. Total Outputs is the number of physical outputs on the controller; each one can be assigned to a clock mechanism, a bell or general-purpose use. Per-type figures are maximums and can’t all be used at the same time.

NTP Sync sets the time automatically from internet time servers, so it requires an internet connection.

Models and specifications may change at any time without notice.

/ How to Choose /

Start with what’s in your tower

Each family is built around what it has to drive. Pick the one that matches your tower, then move up within it for more outputs, more ways to control it, and more to connect.

ChronosOne clock mechanism kept precise by an onboard GPS clock and NTP sync, set up from an onboard OLED and rotary encoder.
Chronos ProUp to 3 clocks and 4 bells, adding stepper clock support, Ethernet + WiFi and ChurchAssistant™ automation.

Agnus

Bells

For towers where the bells come first.

Agnus MiniA single bell output, run from an onboard 7″ touch screen, connected over WiFi with MQTT support and one phone remote.
AgnusUp to 3 bell outputs with the same onboard 7″ touch screen, WiFi and MQTT connectivity, and one phone remote.
