The Phoenix Contact PLC-RSP-24DC/21-21 is a high-performance relay module designed for seamless integration into industrial automation systems. This relay module features a compact design, making it ideal for applications where space is at a premium. It consists of a base terminal block with a spring-cage connection and a pluggable miniature relay with power contact, ensuring reliable and efficient operation.
With a nominal input voltage of 24 V DC, the PLC-RSP-24DC/21-21 offers a typical input current of 18 mA and a power dissipation of 0.43 W under nominal conditions. The relay module is equipped with a yellow LED operating voltage display, providing clear visual indication of its status. It also includes protective circuits such as polarity protection and a free-wheeling diode to safeguard against potential electrical issues.
The contact side of the relay module features two PDT (double-pole double-throw) contacts made of AgNi material, capable of handling a maximum switching voltage of 250 V AC/DC. The module supports a minimum switching voltage of 5 V AC/DC at 10 mA and a maximum inrush current of 15 A for 300 ms. It is designed to handle a limiting continuous current of 6 A, making it suitable for a wide range of industrial applications.
The Phoenix Contact PLC-RSP-24DC/21-21 relay module is built to withstand harsh operating conditions, with an ambient operating temperature range of -40 °C to 60 °C and a storage temperature range of -40 °C to 85 °C. It complies with various international standards, including IEC 60664, EN 50178, and IEC 62103, ensuring high levels of safety and performance.
This relay module is designed for easy installation on DIN rail NS 35/7.5, with a width of 14 mm, height of 80 mm, and depth of 94 mm. It supports a variety of conductor cross-sections, both solid and flexible, ranging from 0.14 mm² to 2.5 mm², and is compatible with AWG 26 to 14.
Ideal for use in control panels, automation systems, and other industrial environments, the Phoenix Contact PLC-RSP-24DC/21-21 relay module offers robust performance, reliability, and ease of use, making it a valuable addition to any industrial automation setup.
