The SCADA 3000 Pulse Count Module is an optional component for use with the Sensaphone SCADA 3000 system. It features 4 totaling pulse count channels and 4 virtual channels that can be programmed to calculate various rates or to display count overflow.
The module has four pulse count channels, each of which is capable of counting pulses at a rate of up to 10,000 pulses per second (10KHz). Each channel will totalize pulses up to one million and then reset to zero. The four virtual channels can be programmed to calculate the pulse as either pulses-per-second, pulses-per-minute, or pulses-per-hour.
The module is compatible with dry contact or solid state pulse generating devices such as relays or switches. The term DRY contact means that there must NOT be any voltage connected to the circuit. The module may also be connected to the logic output of another solid state computer device (e.g., Open Collector, TTL, CMOS). The module includes adjustable filtering for each channel to prevent counting errors generated by the bounce from slow-moving switches.
The two main uses for the Pulse Count Module are
The SCADA 3000 Pulse Count Module splits incoming data into four channels of accumulated pulse, and four virtual channels measuring the rate of pulses, thus generating a total of eight. Thus, you can receive two different measurements from a single input.
Channels 1-4 measure Accumulated pulse from 0 to 1 million, after which the figure resets.
