10-function time relay with start and reset inputs. PCS-516DC

Multifunction time relay – precise time control

The PCS-516DC time relay is a versatile device designed for time control in industrial and home automation. It is ideal for applications such as controlling ventilation, heating, lighting or signaling. Thanks to 10 different operating functions and START and RESET inputs, it offers flexibility and precision in managing time processes. The device is mounted on a 35 mm rail, which facilitates its integration with existing installations.

### Functionality and application

The PCS-516DC relay stands out with a rich set of functions, including delayed switching on, delayed switching off, cyclic modes and pulse generation. START and RESET inputs allow for remote control of the relay's operation, which increases the possibilities of its use in complex automation systems. This makes it possible to precisely adapt the device's operation to specific application needs.

**Versatility in practice:**

• Building automation: Controlling the lighting of corridors, stairs or parking lots with a delayed switch-off.
• Industry: Controlling the working time of machines and devices, controlling production processes.
• HVAC systems: Managing the operation of fans, heaters and air conditioners based on set time schedules.
• Alarm systems: Delaying the activation of the alarm to avoid false alarms.

### Technical characteristics and benefits

The PCS-516DC relay is characterized by a wide range of supply voltage (9 ÷ 30 V DC) and a high load current (8 A DC). Semiconductor outputs (transistor in an open collector configuration) ensure high reliability and long device life – the lack of mechanical contacts eliminates the risk of wear and damage caused by frequent switching. The status of the contact is indicated by an LED, which facilitates monitoring the operation of the relay. In addition, smooth time adjustment in the set range allows for precise adaptation to specific application needs.

**Key features:**

• 10 operating functions: Wide range of application possibilities.
• START and RESET inputs: Remote control of the relay's operation.
• Semiconductor outputs: High reliability and long life.
• Wide supply voltage range: Compatibility with various electrical installations (9 ÷ 30 V DC).
• Smooth time adjustment: Precise adaptation to application needs.
• Mounting on a 35 mm rail: Easy integration with existing automation systems.
• Time ranges: 0.1s - 576 hours – flexibility in choosing the appropriate working time for different applications.

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

The PCS-516DC relay is a solid and reliable solution for professionals and demanding end-users looking for a precise tool for time control in various automation applications. Its versatility and ease of installation make it an ideal choice for both installers and people independently implementing home or industrial automation projects.
