| Explanation: |
Series USS - Slim sockets for one-changeover URS relays; this breakdown covers the ten listed USS-1E and USS-1P socket models. |
Relay Configuration 1 - Socket for a relay with one changeover contact |
Connection E - Screw connection |
Socket Input Group 1 - 24VAC/DC socket input; matching relay URS124D |
USS sockets provide the wiring interface for URS relays with one changeover contact. Screw and push-in versions are available in five socket voltage groups. Select the socket input voltage and the matching relay separately: the higher-voltage socket inputs do not indicate the voltage applied directly to the relay coil.
| Nominal socket input | Screw socket | Push-in socket | Matching relay |
|---|---|---|---|
| 5VDC | USS-1E-5 | USS-1P-5 | URS105D |
| 12VDC | USS-1E-5 | USS-1P-5 | URS112D |
| 24VDC | USS-1E-5 | USS-1P-5 | URS124D |
| 24VAC/DC | USS-1E-1 | USS-1P-1 | URS124D |
| 48VAC/DC | USS-1E-2 | USS-1P-2 | URS148D |
| 60VAC/DC | USS-1E-2 | USS-1P-2 | URS160D |
| 120VAC/DC | USS-1E-3 | USS-1P-3 | URS160D |
| 230VAC/DC | USS-1E-4 | USS-1P-4 | URS160D |
The DC-only -5 sockets require the relay for the selected nominal input voltage. The AC/DC versions include the input-circuit arrangement for the specified voltage group. The gallery shows representative screw and push-in structures; use the exact model code to select the electrical version.
| Characteristic | USS-1E screw models | USS-1P push-in models |
|---|---|---|
| Relay configuration | 1 changeover contact (1CO) | 1 changeover contact (1CO) |
| Height × width × depth | 76.6mm × 6.2mm × 88.2mm | 80.6mm × 6.2mm × 101.5mm |
| Stranded flexible conductor | 0.5-1.5mm² | 0.5-1.5mm² |
| Wire size | 20-16AWG | 20-16AWG |
| Screw tightening torque | 0.5N·m | Not applicable |
| Strip length | 7mm | 7mm |
| Characteristic | All listed sockets |
|---|---|
| Maximum contact-circuit voltage | 250V |
| Maximum contact-circuit current | 6A |
| Dielectric withstand between contacts | 2500VAC for 1 minute |
| Dielectric withstand between coil and contact circuits | 4000VAC for 1 minute |
The fitted relay must also meet the circuit load and switching requirements. The socket limits are independent of the selected control input voltage.
