EL731-24-10

Protection Relays & Systems refer to the safety equipment for power systems.They are used to detect, monitor and deal with faults in electric power system. Different types of protection relays can provide different protection features as monitoring and current indication of power system, circuit disconnect, warning alarms, circuit breaker trip or shutdown. EL731-24-10 is mainly used in many industrial applications.

The EL731-24-10 is a digital time-delay relay with a protected setup. It provides an adjustable time limit for a circuit to stay powered so that a preset power on delay can be set before allowing a device circuit to be powered. When the input device such as a push button or a switch is closed, 10 sets of timing period 1 and time period 2 can be set up. Set up A is the time period for period 1, and set up B is the time period for period 2. This digital time delay relay has a protection function built in to help protect both the input and output devices by detecting any faults in the circuit. A red LED located beside each of the 10 programs shows an error in the circuit.

The EL731-24-10 has an operating voltage of 24VDC or 220VAC, and the operating frequency is from 40-400 Hz. The DC input current is 0.2A, and the AC input current is 0.4A. It has a maximum power capacity of 10W and a net weight of 0.15kg. The dimensions are 93mm x 55mm x 50mm. This time-delay relay features a 6-bit code setting device that can be used to set the timing range for period 1 (from 0~999.9s) and period 2(from 0~999.9min). It also has a red LED display for indicating the status of the relay, such as ON, OFF and ERROR.

The working principle of the EL731-24-10 is very simple. When the input device such as a push button or a switch is closed, it activates the timing module and the output device is powered on. The timer\'s preset timing period1 begins and at the end of the period, it is switched off. The preset timing period 2 also begins and at the end of the period, it is re-activated. During this time, if the input device is closed again, the timer will reset to the starting period and the output device will be powered on again until the input device is closed again.

The EL731-24-10 can be used in a variety of industrial applications including electric power substations, motor protection relays, home appliances withtimer control, fitness equipment, elevator control systems, etc. In order to provide long-time safety and reliability, it also comes with short circuit protection, overload protection, overvoltage protection, overload protection, undervoltage protection, and over temperature protection.

The EL731-24-10 digital time-delay relay is a reliable and safe solution for protecting and controlling electrical circuits. Its accuracy and protection features make it an excellent choice for a variety of industrial applications, suchas electric power substations, motor protection relays and elevator control systems. It is an efficient and cost-effective solution for managing the timing of switching operation in a wide range of applications.
