Get lamp test results you can rely on with this DIN rail diode block from Phoenix Contact. You can mount it in your electrical switchboard and use it to check when electricity is present in a group of circuits. When there's an electrical signal, the circuit's associated diode lights up so you can easily see what's happening. The module is structured to decouple the individual signals from one another, so you won't have to worry about energy transfer giving you false readings.
Built to compact dimensions of 90 (W) x 75 (H) x 55mm (D), with 16 pairs of contacts for efficiency, it's a useful choice for busy setups. It can be mounted in any position, in rows with zero spacing. Screw connections give you a firm hold, even when the module is subjected to vibration.
