10-function time relay 3xNO/NC 100-264V AC/DC PCU-530

Multifunction time relay – reliable time control

The PCU-530 time relay is a versatile device that can be used in a wide range of electrical installations and automation systems. It offers as many as 10 different time functions, allowing precise control of circuits depending on needs. Thanks to the supply voltage of 100-264V AC/DC, it is compatible with most standard installations.

Functionality and application

The PCU-530 relay is not only a timer, but a comprehensive tool for managing time in automation systems. It offers functions such as delayed switching on, delayed switching off, cyclic operation, and the ability to set a fixed on or off time. This makes it ideal for:

• Controlling lighting (e.g. in corridors, warehouses)
• Automation of ventilation and air conditioning systems
• Control of heating devices
• Industrial applications requiring precise time measurement
• Alarm and security systems

Characteristics and benefits

The relay design based on 3 switching contacts (3xNO/NC) provides flexibility in connecting various loads. Mounting on a standard 35 mm rail facilitates installation and integration with existing systems. Additionally:

• Wide time range: from 0.1 seconds to 12 days allows the device to be adapted to the specifics of a given application.
• Smooth time adjustment: allows precise setting of the desired working time.
• Status indication: LEDs indicate the power supply status and contact activation, which facilitates diagnostics and monitoring of the device's operation.
• High resistance: operating temperature range from -25°C to +50°C guarantees reliable operation even in difficult environmental conditions.
• Compact dimensions: a width of only 1 module (18 mm) allows for efficient use of space in the switchgear cabinet.
• Safety: Contact separation provides additional safety of use.

Time ranges include: 0.1 ÷ 1.2 s, 1 ÷ 12 s, 10 ÷ 120 s, 1 ÷ 12 min, 10 ÷ 120 min, 2 ÷ 24 hours, and 1 ÷ 12 days (24 ÷ 288 hours) and 2 ÷ 24 days (48 ÷ 576 hours).

Operation with a newly set time range occurs after switching off and on the power supply – this protects against accidental changes to settings during device operation. The maximum load current of up to 3 x 8 A allows control of various devices with higher power consumption.
