The 460-L is part of a class of devices known as Monitor - Current/Voltage - Relay Output. This device is designed to detect changes in the current or voltage of a circuit, and respond with a signal to activate a relay. This relay can then be used to control a circuit, or to alert personnel when a certain current or voltage is detected.

The 460-L features two types of input: one for current with an input range of 0.5-4 A, and the other for an adjustable voltage from 0-240 VAC. Both of these inputs can be used together, or independently for detecting different levels of current or voltage in a circuit. The device also features a digital display showing the current or voltage being measured. This display can be used to monitor the circuit and assess any problems.

The 460-L also features two different output modes. The first option is a Normally Open (NO) mode, which keeps the relay open until a specific current or voltage is detected; when the threshold is exceeded, the signal to the relay is activated. The second option is a leakage (LK) mode, which closes the relay until a certain current or voltage is detected; when the threshold is exceeded, the signal to the relay is opened. This feature can be used to detect any leakage in a circuit.

The 460-L also has a wide range of automated features. These include an adjustable delay of 0-60 minutes for After Delay Normal (ADN) running, which allows the current or voltage to remain in effect for a specified amount of time after the device was triggered. The device also includes a manual reset for emergency lockout, and an automatic reset when the current or voltage returns to a pre-determined level. Additionally, the 460-L includes an analog output for logging and recording data.

The 460-L is used in a variety of applications where it is necessary to detect changes in current or voltage. This includes monitoring high voltage electricity cables, where it can be used to detect and alert personnel of an interruption or surge in the power supply. It can also be used in industrial plants to detect any overloads in machinery and automatically shut them off when needed, or detect any leakage in sensitive parts of a process. Additionally, the device is used in residential settings to monitor energy usage, and to provide automated shut-off in case of an overload.

The 460-L application field and working principle provide an effective means of monitoring and controlling current or voltage in any application. By controlling the current or voltage with a relay, it allows personnel to monitor and adjust the circuit when necessary. This can be done either manually, or with the automated features to ensure efficient monitoring of the circuit.
