ABB RB122G-24VUC 1SNA645012R2500

ABB Interface Relay 24V AC/DC 8A 2c/o RB122G-24VUC Description The ABB RB122G-24VUC is a high-quality pluggable interface relay designed for industrial control applications. It provides reliable galvanic isolation and signal amplification between control circuits and load circuits. This model features a universal coil that operates on 24V AC or DC, offering excellent flexibility. Its compact design for DIN rail mounting saves valuable cabinet space. Specifications Manufacturer: ABB Type: RB122G-24VUC Part Number: 1SNA645012R2500 Coil Voltage: 24V AC/DC Contact Configuration: 2 c/o (Changeover), DPDT Rated Switching Current: 8 A Rated Switching Voltage: 250V AC Mounting Type: DIN Rail Protection Degree: IP20 Label Info IEC/EN 60947-5-1 AC-12: 230V/8A UL/CSA: 250VAC/8A Application Ideal for use in industrial automation, process control, building automation, and machine building. It is commonly used for switching contactors, solenoid valves, motors, and lamps, as well as for signal multiplication. Country of Origin Made in Morocco by ABB STOTZ-KONTAKT GmbH, Germany. CO2 Impact Opting for this pre-owned component avoids the emission of approximately 2.0 kg of CO2 compared to manufacturing a new one. This saving is comparable to the emissions from a 10 km car journey. Availability This item is in stock and ready for immediate dispatch.

It simplifies inventory management as one relay can be used for both AC and DC control circuits, reducing the need to stock separate models. This is particularly useful in mixed-voltage environments. What does ‘2 c/o’ or ‘DPDT’ contact configuration mean?’2 c/o’ stands for two changeover contacts, also known as Double Pole Double Throw (DPDT). This means the relay has two independent sets of contacts. Each set has a common terminal, a normally open (NO) terminal, and a normally closed (NC) terminal. This allows the relay to control two separate circuits, for example, turning one device on while simultaneously turning another off. Can the relay module itself be replaced without rewiring the base?Yes, this is a key feature of a pluggable interface relay. The relay module (the clear plastic component) can be easily pulled out of the base (the grey socket with screw terminals) and replaced with a new one. This significantly reduces downtime and maintenance effort as the field wiring remains connected to the base. profideals is not an authorized distributor, reseller or representative of the products featured on this website.
