SIEMENS 3UG4615-1CR20 Industrial Controls VOLTAGE MONITORING RELAY

VOLTAGE MONITORING RELAY

The SIEMENS 3UG4615-1CR20 Industrial Controls VOLTAGE MONITORING RELAY monitors high voltages up to 32 V and low voltages down to 0.8 V.

The SIEMENS 3UG4615-1CR20 Voltage Monitoring Relay is a nuclear power relay for switching loads. Use this switch to protect a circuit and equipment from voltage spikes, reverse current, or to eliminate electromagnetic interference (EMI).

The SCR series Voltage Monitoring Relay (VMR) monitors and controls the voltage of a power supply. An increase in line voltage above the selection range of a relay coil can cause an SCR to fail. The VTMR are designed to protect limited life automotive semiconductor devices from excessive line voltage. These relays have low power drain for battery applications and are tested for meeting current leakage requirements.

Stable operation of industrial electrical equipment is a key to reliable performance. Instruments used are known to have an influence, as well as the incoming voltage and the current demand of the customer's process. It is important to detect and respond to voltage variations in a controlled fashion. Voltage monitoring relays are used for this purpose.

The Siemens 3UG4615-1CR20 is a Voltage Monitoring Relay that uses monitored voltage input for trip indication. It monitors the input voltage, and transfers over-voltage or under voltage to the output contacts. The relay attempts to hold the output contacts open when power is turned off. It also keeps switch contacts out of the closed position while the load is being powered up. This helps protect against shock hazards at turn on time.

The SIEMENS 3UG4615-1CR20 is a NAMUR voltage monitoring relay that measures and reports real time power supply availability, particularly useful where control and load currents must not differ from the overall voltage or frequency. With its module technology, the device incorporates all technical components and sensors directly on the printed circuit board

The 3UG4615-1CR20 is a voltage monitoring relay for use in industrial appliances and machines. It detects the voltage value, which may range from 3 to 36 volts AC/DC or up to 80 V DC/AC. Voltages between 111 and 170 V AC may be measured with a separate transformer accessory. Direct current voltages below 80 volts may be measured with an external resistor divider, not supplied. When the measured voltage drops or rises outside the set 4.5 to 36 volt range, the relay changes state after a delay time set by the user by means of a potentiometer between 90 and
