Notes
- Safety information
- A separator plate (e.g., 209-191) must be used for voltages greater than 250 V between adjacent relay modules and for compliance with the reinforced insulation requirements.
- Note
- Reinforced insulation between coil and contactsTo prevent damaging the gold layer, 30 VDC switching voltages and 50 mA currents must not be exceeded. Higher switching power eventually evaporates the gold layer. The resulting deposits in the housing may reduce service life.To protect the relay coils and contacts, inductive loads must be dampened with an effective protection circuit.
Signaling
- Status indicator
- Red LED
