Description
Electromechanical time relay РВ 235 УХЛ4 (direct current)
The РВ 235 УХЛ4 series electromechanical time relay is designed for use in power electrical networks, relay protection devices, and emergency automation (RPA). The device operates in DC circuits as an auxiliary element, providing a precise, adjustable time delay when transmitting command signals for equipment shutdown or switching.
Key Advantages and Features:
- High Accuracy and Stability: The relay's clock mechanism ensures stable operation of the contact group with a set time delay, regardless of ambient temperature fluctuations.
- Easy Adjustment: The scale on the front panel with a rotary pointer allows for smooth and precise setting of the required delay time.
- Transparent Protective Cover: The dust-proof transparent housing allows for visual monitoring of the contact group's status and the operation of the clock mechanism without disassembling the relay.
- Industrial Reliability: The powerful contact group and screw terminals are designed for long service life under conditions of regular vibration and high operational loads.
Compatibility and Application Area:
- Relay protection and automation (RPA) schemes for substations, power plants, and distribution points.
- Control of incoming and sectional circuit breakers in DC circuits.
- Industrial automation systems, protection of electric drives, and technological equipment.

Expert Tip: Before installing and configuring the time delay relay, be sure to check for mechanical damage to the clock mechanism and verify the smooth movement of the pointer. When connecting wires to the screw terminals on the rear/side panel, ensure a secure grip to prevent voltage drops and malfunctions in the relay coil operation.
