Phoenix Contact 2903673

The REL-IR4/LDP-110DC/4X21AU is a plug-in industrial relay designed for high-performance applications. It features four changeover contacts and benefits from additional hard gold plating to enhance contact durability.

With a coil voltage of 110 V DC, the device has an input voltage range spanning from 88 V DC to 198 V DC at 20 °C. It operates in a monostable mode and is polarized. Typical input current at nominal conditions is 8 mA, with response and release times of approximately 13 ms and 14 ms, respectively. The relay also includes a freewheeling diode for protective circuitry and a yellow LED for status indication.

In terms of mechanical durability, the relay is rated for approximately 20 million cycles. It supports a maximum switching voltage of 250 V AC/DC and a minimum switching voltage of 5 V at 24 mA. The relay can handle an interrupting rating of up to 144 W at 24 V DC and supports motor loads in accordance with UL 508 standards.

Dimensions for this relay are 21.2 mm in width, 27.5 mm in height, and 35.6 mm in depth, with a degree of protection rated at RT I. It can operate in ambient temperatures ranging from -40 °C to 70 °C, making it suitable for harsh environments.
