Buffer modules ensure secure DC power supply:
- **Electrical:**
- Input signal 24V DC 900mA.
- Buffer discharge signal: 24V DC 20A or 40A depending on the model.
- **Output Contacts:**
- 2 independent contacts to signal battery discharge.
- **Physical:**
- Metal housing, DIN rail mountable, 4-module width.
- Connection via screw terminals.
- **Secure Power Supply:**
- The buffer module includes a rechargeable battery to temporarily maintain power in case of stabilized power supply failure. The duration depends on the battery capacity and the power drawn.
- Multiple buffer modules can be connected in parallel to increase backup power duration. The module is equipped with contacts to alert when the battery is in use.
- **Compliance:**
- CE, RoHs, Reach.
- **Applicable Standards:**
- EN55032, EN61000-3-2, EN61000-6-2, EN61204-3.
