Alpha 220C LED Sign
The Alpha 220C is a tricolor single-line LED display of 91 cm. 20 characters on 1 line, visible from 26 meters away. Three colors (red, green, amber) for alarm messages, production data and safety communication. Controlled via Ethernet or RS-485.
The Alpha 220C is specially designed to share your messages with your audience as quickly as possible. Its length of 91 cm makes it possible to show 20-character texts in full on a single screen. This versatile LED display is a perfect communication tool to inform, inspire and train your employees.
Best choice for
- Compact single-line communication where space is limited: a 91 cm display, 20 characters
- Clearly legible up to approximately 26 metres (53 mm characters)
- Status at a glance via three colours (red, green, amber)
- Modern integration via Ethernet (AlphaEthernet adapter) — the recommended connection through the Alpha protocol; RS-232/RS-485 standard for backwards compatibility with legacy systems such as a fire alarm panel
Less suitable for
- Full-colour imagery, photos or video — this is a tricolour text display
- Outdoor installation — this is an indoor display (250 nits)
- Long reading distances or longer text — then choose the Alpha 320C (38 m) or 330C (30 characters)
Typical applications
