Counter I/O Board combines three 16-Bit counters with 8 digital TTL input lines and 8 digital TTL output

SCMD200
Counter + I/O board

The SCMD200 Counter I/O Board combines three 16-Bit counters with 8 digital TTL input lines and 8 digital TTL output lines on one board.

Chaining of the counters can be performed via the on-board jumper block of the SCMD200. A 10 MHz oscillator is installed with a jumper providing selection of 5 MHz, 1 MHz, 500 KHz, or 100 KHz oscillator signal for the input to the counters.

The 8 digital TTL input lines have resistor sips installed and can be pulled high or low via on-board jumper, and the 8 digital output TTL lines have a maximum +/-35 ma drive current per line. The 8 output lines can be used to directly control the relays on our RIB101 Relay Board.
