3141 - Multi-Mode Universal Timer

Highly versatile Multi-Mode Timer that features seven different timing modes. A microcontroller is employed to do all the hard work, keeping the size and price down to a minimum.

Four crystal controlled timing periods are provided (1-255 seconds, 10-2550 seconds, 1-255 minutes or 10-2550 minutes). Timing modes and delay ranges set using on-board DIP switches.

Trigger Inputs are opto-isolated. Triggering options available range from simple push button to electrically isolated voltage switching sources, to taking the output from our counter and timer kits 3129 and 3154.

Output is to a mains rated relay.
