What is S0 output?
S0 is an industry-standard pulse output of electricity meters, water meters, gas meters, and so on. In effect, these pulses correspond to the closing of a mechanical contact for 30 to 70 ms. Yes, the device remembers the counter state even after a power outage.
What is pulse output on water meter?
What is Pulse Output? When it comes to water meters, a pulse output is simple SPST (single pole, single throw) dry contact reed switch. The switch is normally open. The switch closes when a magnet is in close enough proximity to pull the reed to the closed position.
What is pulse signal output?
A pulse output signal is a typical method of measurement for electricity, water or gas meters. It’s likely that the meters in your own home will use pulses to define the amount of energy, water or gas passing through them at any given time.
What is a pulse in electricity?
A pulse is a burst of current, voltage, or electromagnetic-field energy. In practical electronic and computer systems, a pulse may last from a fraction of a nanosecond up to several seconds or even minutes.
How does a pulse signal work?
When activated by a magnet in the rotating turbine or gear, the NPN sinks to the zero volt wire, and the signal output value drops. As flow passes through the meter, the sensor is continually switched on and off in proportion, giving the pulse output.
What is a pulse generator used for?
A pulse generator is either an electronic circuit or a piece of electronic test equipment used to generate rectangular pulses. Pulse generators are used primarily for working with digital circuits, related function generators are used primarily for analog circuits.
What is pulse counter used for?
The purpose of the Pulse counter, is to count the number of pulses during a specified amount of time. The time is dictated by the signal on the start/stop pin. When the start/stop pin is high, the algorithm is counting pulses, otherwise the last count value is output.
What is a pulse input module?
Keep a pulse on things. Used in conjunction with the DMS 2.5 Gateways, the Pulse Input Module (PIM) can monitor and record energy consumption from Samsung indoor units or pulse signals from other devices from water, gas, and electricity meters.
What type of signal is pulse?
Pulse Signal The following illustration shows a series of pulses. A Pulse signal is a unidirectional, non-sinusoidal signal which is similar to a square signal but it is not symmetrical like a square wave. A series of continuous pulse signals is simply called as a pulse train.
Is pulse signal analog or digital?
digital signal
PULSE TRAIN SIGNAL CONDITIONING A pulse can be considered a digital signal because only the number of rising or falling edges is measured. In many instances, however, the pulse-train signal comes from an analog source, such as a magnetic pickup.
How do you take a pulse reading?
To check your pulse at your wrist, place two fingers between the bone and the tendon over your radial artery — which is located on the thumb side of your wrist. When you feel your pulse, count the number of beats in 15 seconds. Multiply this number by four to calculate your beats per minute.
What is a pulse generator circuit example?
What is pulse in communication?
A pulse in signal processing is a rapid, transient change in the amplitude of a signal from a baseline value to a higher or lower value, followed by a rapid return to the baseline value.
What is the main function of a pulse generator?
What is pulse signal used for?
Pulse Width Modulation (PWM) is a fancy term for describing a type of digital signal. Pulse width modulation is used in a variety of applications including sophisticated control circuitry. A common way we use them here at SparkFun is to control dimming of RGB LEDs or to control the direction of a servo.
How does the number of S0 pulses depend on consumed energy?
The number of S0 pulses is directly proportional to the amount of consumed energy (e.g. 1000 pulses = 1 kWh). This ratio is specific for the particular 3rd party energy meter.
How does the S0 output of the Damocles work?
The S0 output is connected to a Digital input of the Damocles unit. There are several models availale with 4, 12 or 24 Digital Inputs (DI). All Damocles units feature a has 32-bit digital counter on every DI. The number of S0 pulses is directly proportional to the amount of consumed energy (e.g. 1000 pulses = 1 kWh).
How do I get the pulse value from a 3rd party meter?
Pulse outputs from 3rd party meters (S0 interface) are connected to the Damocles Ethernet I/O unit. Each Digital Input on the Damocles unit features a 32-bit pulse counter. The value of this counter can be read out over the web using most M2M protocols (SNMP, XML, Modbus/TCP).
How do I connect a 3rd party pulse meter to Damocles?
Pulse outputs from 3rd party meters (S0 interface) are connected to the Damocles Ethernet I/O unit. Each Digital Input on the Damocles unit features a 32-bit pulse counter.
