Phoenix Contact 2900323

The Relay Module PLC-RPT-110UC/21AU/RW is specifically engineered for railway applications, comprising a basic terminal block equipped with a Push-in connection and a plug-in miniature relay featuring multi-layer gold contacts. The operational input voltage is rated at 110 V DC, with a permissible range of 77 V DC to 137.5 V DC, ensuring versatile compatibility.

This module operates within a temperature class TX, with an operational range of -40°C to +70°C, making it suitable for extreme environmental conditions. It includes one changeover contact, with a maximum switching voltage of 250 V AC/DC and a minimum switching voltage of 12 V AC/DC. The relay supports a typical input current of 2 mA, with a response time and release time both approximately 4 ms, indicating quick operational capability.

Constructed for durability, the module features a mechanical service life of around 20 million cycles. It is equipped with protective circuits, including surge protection and a freewheeling diode, ensuring reliable performance. The relay is also marked with a yellow LED for operating voltage display, and the contact material is AgSnO, hard gold-plated, which enhances its longevity.

The assembly is designed for DIN rail mounting and can be positioned in any orientation. It adheres to several regulatory standards, including IEC 60947-5-1, and complies with the EMC and Low Voltage Directives. The Designation Code for this product is PLC-RPT-110UC/21AU/RW.
