The RCT404 is a preset counter that counts events, batches, measures frequency, motor-speed, cable-length, acts as a zero-speed switch to detect stoppage of a rotating shaft and more. It features a pushwheel switch for frequent setpoint changes. 

The counter accepts input from proximity switches, photoelectric switches, voltage pulses, limit switches and electromagnetic pickups amongst others. The RCT404 features a single 4-digit LED display, which indicates the measured process value. 2 additional LEDs indicate the status of 1 relay and 1 setpoint. Operators view and change the single setpoint on the display via the pushwheel on the front of the unit.

The counter can count a range of 0 to 999999 with absolute accuracy and measure 0.06 - 9999 RPM within 0.05% of the reading. The RCT404 features 2 user-programmable electromagnetic relays for process control as well as retransmits an isolated output signal to other devices such as a Programmable Logic Controller (PLC) or Solid-State Relay (SSR). Signal isolation protects your devices and machines downstream of our instruments from damaging fluctuations in the input signal. The counter can measure frequency up to 5000 Hz.
