Installation & Field Application Guide
- Mount the relay on standard 35mm DIN rail. Ensure the rail is properly grounded.
- Connect AC supply to coil terminals A1 and A2. Use 14 AWG wire rated for 230 VAC.
- Wire load circuits to the appropriate contact terminals (NO/NC). Torque terminals to 0.5-0.6 Nm.
- For inductive loads (contactors, solenoids), install an RC snubber across the contacts to suppress arcing.
Why Choose the RCM 230VAC 3C/0
- DPDT configuration provides versatile switching options for control circuits.
- 10 A contact rating handles heavy loads including motors and heaters.
- Wide operating temperature range (-40°C to +55°C) suits demanding environments.
- DIN rail mounting simplifies installation and maintenance in control panels.
Field Engineer FAQs
Q1: What is the coil power consumption of this relay?
A1: The 230 VAC coil typically consumes 0.9 VA (approx. 4 mA at 230V), making it suitable for direct PLC output driving.
Q2: Can this relay be used for DC loads?
A2: Yes, the contacts are rated for 10A at 24 VDC. However, for DC loads above 50V, derating may apply due to DC arc characteristics.
Q3: What is the expected mechanical life of the RCM relay?
A3: The relay offers >10 million mechanical operations and >100,000 electrical operations at rated load.
