Count pulses and measure pulse rate.
Counts input pulses from flowmeters, turnstiles, shaft rotation sensors, etc. and reads digital inputs from switches and sensors. The unit is housed in a bulkhead/wall mount aluminum enclosure. Data is output by RS232 serial connection to host PC over DB9 connector and software is supplied to read and display the data. The serial interface is also fully documented so you can integrate the PRT232 into your own custom written software.

The counter is also available with eight digital power outputs rated for driving relays, solenoid valves, or high-current annunciator LEDs such as 1W Luxeon LEDs.
Pulse counter with output power drivers
PRT232A..................................................................$139.00

The PRT232 counter is also available in a heavy duty die cast aluminum enclosure that can be wall or bulkhead-mounted. This is a NEMA4 (washdown proof) enclosure and is ideal for industrial applications or installations where a bare circuit board can be damaged. This version includes 4' cables for power and pulse input connections. Cables exit the enclosure through a gland seal that provides strain relief and protects internal connectors against accidental tension on the cable. PRT232E.................................................................$179.00

This is a 12 Volt power supply suitable for powering the PRT232. Provides 12V unregulated at 300mA with mating connector for PRT232 power input. PS12V3.....................................................................$12.95
