The ACT-2A is a front panel programmable for single or multiple pulses per revolution and for scaling. The ACT Series Panel Instruments offer a fixed and floating decimal point and can be supplied with Remote Optical, Infrared, Laser, Proximity, and Magnetic Sensors, and are directly compatible with a TTL input and a 200mV to 50 Vac signal.
