Monitor - Current/Voltage - Relay Output

84871020 is a monitoring device which can be used for monitoring input current and/or voltage, and to provide an output signal to a relay to initiate an action. The 84871020 features an accurate, isolated, adjustable output-level sensing devices and a wide range of power monitoring options for single or multiple channels.

Application Field

The 84871020 is generally used for monitoring and control of AC and/or DC voltage and current. It is used in many industrial applications such as motors, lights, pumps, and other materials, as well as in telecommunications, medical, and automotive industries. It can be used for alarm systems, control systems, process monitoring systems, and in any other system that requires the monitoring and control of current or voltage.

Working Principle

The 84871020 works by monitoring input current and/or voltage and provides an output signal to a relay to initiate an action. The device has an isolated, adjustable output-level sensing device, and is able to measure both AC and DC voltages. The device is also able to measure both AC and DC currents, and to measure and hold voltage and current on separate channels.

The 84871020 uses an internal relay for the output of monitored signals. This output can be used to initiate an action, such as activating an alarm, a relay, or a motor. The settings of the device can be adjusted manually or remotely through an external control system. The settings can also be saved in memory for later use.

The 84871020 can be used in various applications, such as AC and DC current/voltage monitoring and control, data logging and recording, remote monitoring and control, and alarm triggering. The device can also be used for monitoring and protecting motors, lights, pumps, and other materials, as well as in telecommunications, medical, and automotive industries.
