3RQ3118-1AM00
The Siemens SIRIUS 3RQ3118-1AM00 is a pluggable relay output coupling module with one set of normally open contacts, 24V DC coil voltage, screw terminals, and a housing width of 6.2mm. It allows for pluggable replacement of internal relays, facilitating the isolation and coupling maintenance of PLC control circuits and field signals.
Product Positioning
The 3RQ3118-1AM00 is a coupling module in the Siemens SIRIUS 3RQ3 series that uses pluggable relay outputs. It can provide signal isolation and conversion between PLC and field devices, and supports pluggable replacement of relays for easy maintenance and management.
Core Product Advantages and Features
Plug-in relay design
The internal relays adopt a pluggable structure, which can be directly replaced in case of failure without disassembling the entire module wiring, greatly shortening maintenance time.
1 set of normally open contact outputs
It provides one set of normally open (NO) contacts, which can convert 24V DC control signals into corresponding switching actions to connect to downstream control equipment.
24V DC coil voltage
The coil has a rated voltage of 24V DC, which is suitable for low-voltage DC signal circuits commonly found in PLCs or control panels.
Narrow housing and screw terminals
With a casing width of only 6.2mm and screw terminal wiring, it saves installation space inside the control box and facilitates wiring construction.
