3RQ3038-1AB00
The Siemens SIRIUS 3RQ3038-1AB00 is a 24V AC/DC input coupling relay with one set of switching contacts, AgSnO2 contacts, a thermal current of 6A, screw terminal wiring, and a mechanical life of 10 million cycles. It is suitable for low-voltage signal isolation coupling applications in PLCs.
Product Positioning
The 3RQ3038-1AB00 belongs to the SIRIUS 3RQ3 input coupling relay series, specifically the 24V AC/DC specification. It is the most common model among the three coil voltage versions (230V/115V/24V) used for low-voltage signal isolation in PLCs.
Core Product Advantages and Features
24V AC/DC universal coil
The coil can accept 24V AC or DC, covering common voltage specifications for general PLC digital outputs.
1 set of switching contacts, AgSnO2 material
It provides one set of switching (CO) contacts, made of AgSnO2 material, which balances conductivity and anti-welding capability.
6A thermocurrent output
The contact thermal current is rated at 6A, which can directly drive general contactor coils or indicator lights and other loads.
Narrow fixed structure
The housing is 6.2mm wide and features a non-plug-in design, ensuring stable and reliable contact during long-term use.
