The interface relay Relpol PIR6W-1P-24VDC-01 Interface Relay 1P 6A 24V DC is compared with several alternative Relpol relay models. All these products are designed for industrial automation, circuit switching, and signal isolation, but they differ in pole count, contact materials, coil control voltage, and physical dimensions.
⚙️ The table below compares characteristics such as device type, contact configuration, coil voltage, housing width, and connection features to highlight the technical differences between the models.
| Parameter | Relpol PIR6W-1P-24VDC-01 | Relpol PI71P-024DC-Y42G-RS-2011 | Relpol PI72P-024DC-Y42G-RS-2012 | Relpol SIR6WB-24VDC-R | Relpol PIR6WB-1PS-24VAC/DC-R | Relpol PI71P-230AC-Y93G-RS-2011 | Practical conclusion |
|---|
| Device type | 1P interface relay | 1P interface relay with AgNi contacts | 2P interface relay with AgNi contacts | Slim interface relay | Slim 6.2mm 1P interface relay | 1P interface relay with AgNi contacts | All products provide signal switching, but vary by channel count and physical construction. |
| Control voltage | 24V DC | 24V DC | 24V DC | 24V DC | 24V AC/DC | 230V AC | 24V DC models fit standard automation setups, the 24V AC/DC version offers broad supply compatibility, and the 230V AC version suits mains voltage circuits. |
| Contact configuration | 1P (one changeover contact) | 1P with AgNi contacts | 2P (two contacts) with AgNi | Standard configuration | 1P | 1P with AgNi contacts | The 2P model allows switching two independent circuits simultaneously, while the other options are single-pole. |
| Housing and mounting | Standard panel mount design | Standard design | Standard design | Compact space-saving design | Slim 6.2mm housing with spring terminals | Standard design | Slim profiles and spring terminal versions are better suited for high-density control cabinets. |
◎ The table below evaluates which product is most suitable for different user needs and installation scenarios.
| Use case | Recommended product | Why |
|---|
| Standard signal switching in 24V DC automation | Relpol PIR6W-1P-24VDC-01 | Delivers reliable switching performance for standard 24V DC control circuits. |
| Switching two independent circuits simultaneously | Relpol PI72P-024DC-Y42G-RS-2012 | Features a dual-pole 2P configuration to manage multiple lines at once. |
| Installation in space-constrained control panels | Relpol SIR6WB-24VDC-R or PIR6WB-1PS-24VAC/DC-R | Features a slim 6.2mm width to maximize cabinet packing density. |
| Operation on 230V AC mains voltage | Relpol PI71P-230AC-Y93G-RS-2011 | Designed specifically for systems operating on 230V AC coil control voltage. |
The Relpol PIR6W-1P-24VDC-01 Interface Relay 1P 6A 24V DC is ideal for standard industrial automation tasks requiring 24V DC control. Choose it for reliable single-pole signal isolation and switching on standard panels. If you need dual-pole switching, AC/DC versatility, 230V mains compatibility, or an ultra-slim profile for tight spaces, one of the alternative Relpol models will be more suitable.
