• Coil voltage: 48VDC (identical)
• Contact form: DPDT (2 Form C) (identical)
• Contact rating: 6 A (identical)
• Switching voltage: 250VAC, 250VDC - Max (identical)
• Coil current: 20 mA (identical)
• Coil type: Non Latching (identical)
• Mounting type: DIN Rail (identical)
• Termination style: Spring Terminal (identical)
• Operating temperature range: -40°C ~ 60°C (identical)
• Contact material: Silver Nickel (AgNi), Gold (Au) (identical)
• Coil resistance: 2.4 kOhms (identical)
• Timing characteristics: 8 ms operate, 10 ms release (identical)

The 2900340 is an active product from the PLC-RPT series, providing continuity for applications previously using the obsolete 2912594 from the PLC-RSP series.
