DIN Rail Terminal Blocks with Varistors

The DAS.4/V type of multiple level terminal block is equipped with a varistor connected between the upper and lower levels and can be used to restrict voltage peaks due to surges, static discharge, and inductive load switching.  The varistors have a response time of 20-25ns, which is longer than that of the suppressor diodes, <1ns, with a higher response voltage and withstanding higher discharge currents.  The ability to withstand a higher discharge current makes them suitable for uses with strong transients, with currents up to 4500A pulse 8/20ms.  ASI offers a range of multiple level terminal blocks equipped with varistors from 24 volts to 230 volts so they can be used to protect signal and power supply circuits.

When the DAS.4/V is used it can provide effective protection against differential mode interference (diagram 2) for inputs and outputs of industrial PLC's, DCS systems and PC's, signal conditioners and sensors and also for power supply units of electronic equipment in general.

In addition to the above mentioned varistor models of terminal blocks ASI offers a wide range of multiple level terminal blocks equipped with diodes.  Each model can be used for a specific purpose such as protection against power supply reversal, lamp test circuits, blocking excess current from solenoids, relays, etc.

Multiple level terminal blocks are also available which allow for the customer to add their own components, or for ASI to add components selected by the customer.  There are also blocks and housings which can be used to add a small printed circuit board which may be designed with a more complete circuit.  These same products are also available with both electromechanical and solid state relays.  Check the factory for specific details.  1(877)-650-5160.
