Time relay 12-240V AC/DC Type: PCM-01/U EXT10000074

Multifunction time relay – precision and reliability in automation

The PCM-01/U time relay is a versatile device designed to perform delayed switching functions in automation and control systems. Its wide time setting range, from 0.1 seconds to 10 days, allows it to be adapted to various applications – from simple delays in lighting circuits to more complex industrial processes. The relay is triggered by the supply voltage, ensuring reliable operation and easy integration with existing systems.

Functionality and construction for professionals

PCM-01/U stands out not only for its wide time setting range but also for additional functions, such as permanently switching the receiver on or off. Status indication – supply voltage, relay status and time measurement – using LEDs, facilitates diagnostics and monitoring of the device's operation. The single-module housing (17.5 mm) allows for easy mounting on a TH 35 rail, saving space in the distribution box. The relay output with changeover contacts with a maximum load capacity of 16 A ensures compatibility with various types of loads.

Key features:

• Wide supply voltage range: 12-240 V AC/DC – versatility of use in various installations.
• High time accuracy: ensures precise process control.
• ON/OFF functions: allow permanent switching of the receiver on or off, increasing system flexibility.
• LED indication: informs about the status of the supply voltage, relay operation and time measurement – facilitates diagnostics.
• Mounting on TH35 rail: standard mounting in electrical distribution boards.
• Single-module housing: compact dimensions allow for efficient use of space in control cabinets (90x17.5x66 mm).
• 1NO/NC relay output: allows control of various types of loads (maximum current 16A at 250V AC).
• Time setting range: discrete settings allow precise adaptation to application needs (from 0.1 s to 10 days).
