Selco M4700-00 Alarm Indicator

Selco M4700-00 Alarm Indicator is a 20-channel flush-mounted LED indicator panel that displays the status of up to twenty potential-free contacts in a control system. It runs from a 24 V DC supply (±25%), with 20 inputs and plug-in LEDs, and includes a front-test push button to illuminate all channels for quick verification plus an auxiliary push button for application-specific use. Sized at 144 x 144 x 67 mm with a 138 x 138 mm panel cut-out, it weighs about 0.5 kg and has IP31 front protection; operating temperature is -10°C to +70°C, and it is CE-marked per EN50081-1, EN50082-1, EN50081-2, EN50082-2. A legend card between the front covers allows channel descriptions, and the same connection approach can be used with SELCO’s M4500 and M4600 panels.
