Programmable impulse time switch PCZ-523, 2x125 entries, contact: 1P, I=16A, 24÷264V AC/DC, 2 modules

Time switch PCZ-523 – precise time control

The programmable time switch PCZ-523 is a reliable device designed for automatic switching of electrical devices on and off. It is ideal for both home and industrial installations where precise time control is required. It is particularly well suited for cyclical applications such as school bells, outdoor lighting or irrigation systems.

The clock offers a wide range of programming options, allowing you to create individual schedules tailored to specific needs. This gives the user full control over the operation of connected devices, which translates into energy savings and increased comfort. DIN rail mounting simplifies integration with existing electrical infrastructure.

Functionality and possibilities

PCZ-523 stands out for its versatility and a rich set of functions. It allows programming in daily, weekly mode and using special cycles (weekdays, weekends). The pulse length (on-time) can be set in the range of 1 second to 99 minutes and 59 seconds, allowing for precise adaptation to specific applications. Additionally, the clock has a manual control function, which allows for immediate switching of the circuit on or off without changing the program. Automatic daylight saving time correction ensures accurate operation throughout the year.

• Pulse program: ideal for short-term activations, e.g. school bells.
• Two program lines: allow you to create alternative schedules for one receiver.
• Automatic time change: eliminates the need to manually adjust the time with the change of season.
• Manual operation: allows quick switching of the circuit on or off without modifying the program.
• Large number of memory locations (250): provides flexibility in creating complex schedules.
• Wide supply voltage range (24-264V AC/DC): increases the versatility of the device and allows it to be used in various electrical installations.

Construction and mounting

The PCZ-523 clock has been designed with easy mounting and intuitive operation in mind. The housing with a width of 2 modules (35 mm) allows it to be placed in a standard distribution box on a DIN rail. Screw terminals with a capacity of 4 mm² ensure safe and durable connection of electrical wires. The device is characterized by high resistance to electromagnetic interference and stable operation in a wide temperature range (from -20°C to +50°C). The IP20 protection class provides protection against touching with fingers and against access to small solid objects. The clock is equipped with a lithium battery type 2032, which ensures maintenance of settings in the event of a power failure for a period of up to 6 years.
