Phoenix Contact 2900322

The PLC-INTERFACE is specifically intended for railway applications, integrating a basic terminal block with a Push-in connection and a miniature relay equipped with multi-layer gold contacts. This module operates within a voltage range of 0.7 x U_N to 1.25 x U_N and is rated for input voltage of 72 V DC. It supports temperature class TX, functioning effectively between -40°C to +70°C. The module includes one changeover contact and is designed to withstand an operational factor of 100%.

Constructed for robust performance, this relay module features a mechanical service life of approximately 20 million cycles. The product meets various standards including IEC 60947-5-1 and is categorized under overvoltage category III with pollution degree 2. Electromagnetic compatibility is ensured in accordance with the EMC directive, making it suitable for installation on vehicles.

In terms of dimensions, the relay module measures 6.2 mm in width, 80 mm in height, and 94 mm in depth. It is designed for DIN rail mounting, allowing for flexible installation in various orientations. The Push-in connection method simplifies wiring, accommodating conductor cross-sections from 0.14 mm² to 2.5 mm². For operational safety, the relay provides surge protection and a freewheeling diode, with an operating voltage display indicated by a yellow LED. The relay contacts are made from AgSnO material and are hard gold-plated, ensuring reliable switching capabilities.
