The Six Digit Ratemeter or Totalizer can measure rates from 0.5 Hz to 30 kHz. It totalizes up or down from -99,999 to 999,999 or can act as an accumulating stopwatch. There is a 1/8 DIN case which has five programming keys. It features a 6-digit, 7-segment LED which is 14.22mm high.
The signal input choices are selectable by DIP switch. It is TTL compatible with protection to 25V and high level signals are protected to 115V. It is an open collector of PNP or NPN sensors. The device operates at low level (25mV rms).
The Six Digit Ratemeter offers excitation outputs of 12.5V to 100mA, 8.2V to 70mA and 5.0V to 50mA. A RS-232 output is optional as are dual 5A form C relays and analog output which is scalable, at 4 to 20 mA, 0 to 20 mA, 0 to 10 V.
