Don't let sudden spikes upset your inductive loads – use this diode block from Phoenix Contact. It has four diodes that only allow current to flow one way, from the bottom terminals to the top. This limits any reverse flow, to regulate your electrical circuit and suppress surges. Individually connected, each one of these 1N4007 types of diodes can handle a 1300V peak. This means the protection of high-power circuits is no problem.
This diode device is handy for improving the operation of motor and machine monitoring systems as well as relays and solenoid valves. The front is clearly labelled with a circuit diagram for easy wiring and the rear is fitted with a clip for quick DIN rail mounting.

• Clear cover to protect the diodes
• Green housing makes it easily identifiable as a safety module
• Dimensions of 75 (L) x 22.5 (W) x 55mm (D) mean it's compact
• Wide operating temperature range between -20°C and +50°C to handle harsh conditions
• Screw terminals for a dependable wire connection, even with vibration
