4-digit stopwatch timer board with Start, Pause, Stop, Display Toggle and Reset functions. Displays time elapsed in Seconds and Hundredths. At the end of every minute the display changes over for 1 second to show the elapsed Hours and Minutes time. It then reverts to displaying and counting second. An open collector output pulses low for 20mS on the minute when the timer is running. Maximum time is 99H 59M 59.99S.
The stopwatch functions operate as follows:
The board has an active low open collector transistor output (NPN, 100mA @ 30V). This can be used with to drive our 3156 relay boards or the 3141 delay timer board. Please refer to individual firmware documentation for details of how the output behaves.
Connections: DC IN, RESET, OUTPUT, STOP and START are brought out to a 10-way header strip for easy connection.
START and STOP buttons are also provided on the board.Custom Firmware Design Service
