IMService has released a new relay control box for Sherline, Taig, mini
and micro mill, and desktop CNC router sized CNC machines.
The box has opto-isolated circuits for spindle and coolant. It uses magnetic relays
to better handle the inductive loads encountered in motor starting.
It is plug compatible with our SYS-3A, DeskCNC servo controllers and can be easily
adapted to other systems with 5v signal levels.
