Interface relay Push-in 1P, 16A, 24 V AC PI85-024AC-M91G-PS-2011 864837

Interface relay – reliable connection in automation systems

This interface relay, catalog number 864837, is a key element in electrical installations and automation systems. Designed to operate at 24 V AC, it provides reliable switching of circuits with a current of up to 16A. Its construction based on Push-in connectors significantly simplifies and speeds up installation, and the included accessories increase functionality and safety.

Construction and application

This relay consists of an RM85 relay in a standard white housing, a Push-in socket GZP80, an ejector clamp GZP80-0400 and a surge protection module M91G with an LED. This configuration makes it a complete solution ready for immediate use. The relay is used to control various devices, such as lighting, heaters, pumps or fans. Thanks to its compact design (97 x 15.9 x 75.8 mm), it is ideal for spaces with limited surface area. Mounting is possible both on a 35 mm rail and directly on a mounting plate using a single M3 screw.

Key features and benefits

• Quick installation: Push-in technology eliminates the need for tools when connecting wires – simply press the wire into the terminal. This saves time during both installation and service.
• Versatility: The relay works with comb connectors of the ZGZP type, which allows for easy expansion and modification of the installation.
• Safety: The surge protection module M91G protects the circuit against harmful overvoltages, increasing its lifespan and reliability. The LED indicates the operating status of the relay.
• Durability: The AgNi (silver-nickel) contact material ensures high resistance to wear and corrosion, guaranteeing long-term operation.
• Universality: Intended for AC (16 A / 250 V AC) and DC (16 A / 24 V DC) circuits, it makes it an ideal solution for a wide range of applications.
• Compact dimensions: Allow mounting in tight spaces without compromising functionality.

Technical parameters in practice

The relay is characterized by a coil voltage of 24 V AC and a single switching contact (1P). Its AgNi contact material ensures a stable electrical connection and high resistance to arcing. The rated current of the contacts is 16A for both AC and DC circuits, making it a universal solution for many applications. The operating temperature is in the range of -40°C to +70°C, which allows its use in harsh environmental conditions. The housing has a protection class of IP20, which provides basic protection against accidental contact.
