3141 - Multi-Mode Universal Delay Timer

Highly versatile microcontroller based Multi-Mode Timer that features seven different timing modes that cover a good variety of applications (see User Manual for details).

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 include simple push button, electrically isolated voltage switching sources or taking the output from our counter and timer kits like 3129 and 3154.

Output is to a SPDT relay with NO, NC, C connections (Relay FAQ).
