4-digit 40MHz auto ranging frequency counter board. Two ranges: under 10KHz (1Hz resolution, 0.1 second gate speed); above 10KHz (10Mhz resolution, 1 sec gate). Auto range switching.
The board has an active low open collector transistor output (NPN 100mA, 30V max.). This is active when the counter is operating in the high range above 10KHz.
Connections: DC IN, RESET, OUTPUT, STOP and START are brought out to a 10-way header strip for easy connection.
