The ESX10-T unit expands the "electronic overcurrent protection" product group for DC 24 V applications.
With a width of only 12.5 mm, it selectively protects all DC 24 V load circuits. This is achieved by a combination of active electronic current limitation in the event of a short circuit and an overload cut-off from 1.1 x IN.
The ESX10-T can be snapped directly onto the top-hat rail and thus offers fast and flexible mounting for groups of devices with several circuits.
DC 24 V switching power supplies are very often used in automation technology. In the event of an overload, however, they regulate the output voltage that is to supply all connected loads. So if a fault occurs in a single load in the system, the voltage also drops in all other load circuits. Often, this results not only in an undefined fault condition, but even in a standstill of the machine or system.
This is exactly where the ESX10-T intervenes by reacting faster than the switching power supply to the overload condition. The maximum possible overcurrent is always limited to 1.3...1.8 times the selected rated current (see Table 1). This makes it possible to switch on capacitive loads up to 75,000 μF, but they are only switched off in the event of an overload or short circuit. For adaptation to the load conditions, the rated current is available in fixed values of 0.5 A...12 A and adjustable, e.g. [2 A/4 A/6 A].
Operating and error states are indicated by a multi-coloured LED, an integrated short-circuit-proof status output or individual or group alarms. Remote operation is possible via a remote reset signal or a remote ON/OFF control signal. The manual ON/OFF switch directly on the unit allows targeted commissioning of individual load circuits. As soon as the ESX10-T detects an overload or short circuit in its load circuit, it disables the load output transistor and thus interrupts the current flow in the faulty circuit. Once the fault has been rectified, the load output of the ESX10-T is reactivated by an electronic reset signal or manually by pressing the ON/OFF switch directly on the unit.
