Interface relay PI84-024DC-M41G-MS-2012, contacts: 2P, supply: 24VDC, load current: 8A, width: 15.5mm with GZM80 socket 862190

Interface relay for automation and control

The PI84-024DC-M41G-MS-2012 relay is a component designed for use in automation, control and security systems. It provides reliable circuit switching, galvanic isolation of input from output and is ideal for working with loads up to 8A. The set includes a GZM80 socket, making mounting and replacement easier.

Construction and functionality

This relay is characterized by a double-pole switching contact (2P), which means the ability to simultaneously switch on or off two independent circuits. The coil supply voltage is 24V DC, and the presence of a freewheeling diode protects against damage caused by back EMF. An LED indicator signals the relay's activation status. Mounting is possible both on a 35mm rail and on a mounting plate using a single M3 screw – this provides flexibility in choosing the installation method.

Applications and benefits

This relay finds application in a wide range of devices and installations, such as:

• Building automation: controlling lighting, heating, ventilation.
• Alarm systems: activating sirens, signaling a threat.
• Motor control: switching motors on and off with low power.
• Programmable Logic Controllers (PLCs): expanding the number of control outputs.
• Switching power supplies: protection against overvoltage and short circuits.

Thanks to its compact dimensions (78.1 x 15.9 x 66.5 mm), the relay easily integrates with existing systems. Galvanic isolation between the input and output circuits increases safety and interference resistance. The included GZM80 socket allows for quick mounting and dismounting without the need for tools – which is particularly important during service or modernization of installations. Screw terminals guarantee a secure connection of wires.
