CR Magnetics CR9650-25-NPN-M Adjustable NPN Transistor Output Current Switch with Mounting Case, Normally Open, 30 VDC, 0.59" Window Diameter, 25 Input Range

 PartNumber: CR9650-25-NPN-M   |   Asin: B005CWOXVI

This CR Magnetics current switch has an adjustable set point, an NPN transistor, a mounting case, normally open (NO) contacts, a maximum off-state voltage of 30VDC, and is suitable for use in applications that require an "on" or "off" indication of current flow. This self-powered current switch has a 0.59" window diameter for routing the current-carrying wire and a calibrated dial for adjusting the set point. When current levels rise above the adjusted set point, the switch will turn the output to full on. It is only recommended for applications where the continuous operating current is above the rated full on level of 1.0 amps. This current switch has a mounting case for securing to equipment such as a programmable logic controller (PLC) and is suitable for use in monitoring electrical loads in power-using equipment such as heating elements and motors.

Standards met RoHS (Restriction on Hazardous Substances)
Relay switches (also called an electrical relay or an electrical relay switch) use a small amount of power to control a larger source of power connected to electrical devices such as car motors, computers, and lighting installations. A basic relay switch has a control circuit with an electromagnetic coil and a load circuit with contacts and a lever. When current flows into the relay switch, it moves through the coil and a magnetic field is created, which causes the lever in the load circuit to move between contacts, either turning the device on or off. In a normally open (NO) relay switch, when power is supplied to the relay, the load circuit is closed and the power source connected to the relay is turned on. In a normally closed (NC) relay switch, when power is supplied to the relay, the load circuit is open and the power source connected to the relay is turned off. In other types of relay switches, non-moving parts such as transistors or semiconductors can be used as the control circuit to operate the switching mechanism. Relay switches can be controlled with an external switch, such as a light switch, or they can be connected to an automatically switched power source, such as a car ignition. One relay can operate multiple switches, and multiple relays can be operated with a single switch, with each relay operating independently from the other relays in the system.

CR Magnetics manufactures electrical sensors, indicators, and displays. The company, founded in 2004, is headquartered in Saint Louis, MO.

  • Current switch for monitoring current flow
  • Current carrying wire is routed through an aperture

INA219 High Side DC Current Sensor Breakout - 26V 3.2A Max

Model: ina219-FBACA   |    Mpn: 58-1B8R-D1V5   |    Ean: 0720189972614   |    PartNumber: 58-1B8R-D1V5   |   Asin: B00I827TUQ

This breakout board will solve all your power-monitoring problems. Instead of struggling with two multimeters, you can just use the handy INA219B chip on this breakout to both measure both the high side voltage and DC current draw over I2C with 1% precision. Most current-measuring devices such as our current panel meter are only good for low side measuring. That means that unless you want to get a battery involved, you have to stick the measurement resistor between the target ground and true ground. This can cause problems with circuits since electronics tend to not like it when the ground references change and move with varying current draw. This chip is much smarter - it can handle high side current measuring, up to +26VDC, even though it is powered with 3 or 5V. It will also report back that high side voltage, which is great for tracking battery life or solar panels. A precision amplifier measures the voltage across the 0.1 ohm, 1% sense resistor. Since the amplifier maximum input difference is 320mV this means it can measure up to 3.2 Amps. With the internal 12 bit ADC, the resolution at 3.2A range is 0.8mA. With the internal gain set at the minimum of div8, the max current is 400mA and the resolution is 0.1mA. Advanced hackers can remove the 0.1 ohm current sense resistor and replace it with their own to change the range (say a 0.01 ohm to measure up 32 Amps with a resolution of 8mA) We include a 6-pin header (so you can easily attach this sensor to a breadboard) as well as a 3.5mm terminal plug so you can easily attach and detach your load. Usage is simple. Power the sensor itself with 3 to 5VDC and connect the two I2C pins up to your microcontroller. Then connect your target power supply to VIN+ and the load to ground to VIN-. Adafruit has an Arduino library right now that will do all the gain, range and math for you - just plug and go!

Features

  • Requires soldering of header pins (easy!)
  • Measure high side voltage and DC current draw
  • Great for tracking battery life or solar panels
  • Supported by Adafruit Arduino libraries!
  • Perfect for your solar or battery powered Arduino project

Loulensy AC Current Transducer Sensor Transformer 0-10A 20A 50A User-selectable Input with 0-10V DC Output

 PartNumber: FCS521-SD-10V   |   Asin: B00KIKFDAO

Application FCS series current transducer combines a solid-core current transformer and signal conditioner with top-mounted terminals, and is suitable for use in industrial automation systems. The transducer provides average root-mean-square (RMS) measurement for sinusoidal alternating current waveforms, with an accuracy of 1.0% full scale (FS) and a response time of 100 ms for voltage output models and 300 ms for current output models (10-90% step change). User-selectable input current ranges reduce inventory needed. This current transducer is Underwriters Laboratories (UL) listed and Conformit Europ enne (CE) certified for quality assurance. It is suitable for monitoring linear, constant-speed alternating current (AC) loads that produce sinusoidal waveforms. Current transducers are used to detect electrical current flowing in a wire or cable, and to generate an electrical signal proportional to the current for measurement or control. The transducer consists of an electrical winding, a magnetic core, and a signal conditioner. When current flows through a wire, the transducer winding generates a current, which produces a magnetic field in the core, which then creates a proportional current or voltage output signal. Current transducers are used in industrial automation systems for monitoring, alarming, and equipment control. Warranty & Return 1.24 MONTHS QUALITY guarantee.
