Specifications:
The Moeller DIL R40 is a classic industrial auxiliary contactor relay bundled with a compatible
Murrelektronik RC surge suppressor module (Art. No. 21028).
The “21028 resistor” is an
RC (Resistor-Capacitor) network snubber manufactured by Murrelektronik. It plugs directly into the contactor’s coil terminals to absorb high-voltage voltage spikes (transients) generated when the contactor coil is de-energized, protecting nearby PLC outputs and sensitive electronics from electromagnetic interference (EMI).
- Contact Configuration: 4 NO (4 Normally Open contacts, terminal pairings: 13-14, 23-24, 33-34, 43-44).
- Thermal Current (\(I_{th}\)): 16 Amps continuous.
- Control Coil: Commonly available in 110V/120VAC or 24VDC configurations (verify your specific variant via the side label).
- Application: Used for control circuit logic, interlocking, and switching small inductive or resistive loads.
- Part Number / Art. No.: 21028
- Model Type: RC-BDIL/250(ME)
- Voltage Rating: Optimized for 110V AC to 230V AC coil systems.
- Function: Suppresses arcing and electrical noise directly at the coil
