Safety is a one-way street: Find out with Connectwell Diode Modules

Connectwell Diode Modules: From their invention in 1874, diodes have become integral to the electronic industry. At first, a primary component in radio equipment, diodes have now become essential across almost every type of electrical application.

Diodes Modules are the great valves of the electrical industry

As a two-terminal, semiconductor passive component, a diode conducts a current in one direction and blocks the current in the reverse direction. Due to this zero resistance in forward mode and higher resistance in reverse direction, Connectwell Diode Modules are utilised in Protection and Lamp Test applications.

Connectwell Protection Diode Modules

Connectwell Diode Modules are an effective protective element in applications where expensive electrical components could be damaged by uncontrolled current. In the role of protective elements, Connectwell Diode Modules can be used for polarity or freewheeling protection.

For Polarity protection

Connectwell individual channel diode module offers polarity protection as the diode allows the supply of current in a single direction and acts as a shut-off mechanism whereby, current is blocked from being conducted in the reverse direction.

For Freewheeling protection

Under the Law of Electromagnetism, an inductive load stores energy.Therefore, while turning off an inductive load, the energy stored inside may discharge through the power source causing damage in the power source. Here’s where a Connectwell Individual diode module or common anode diode module is used as a freewheeling diode, by placing it across the load, to safely discharge the energy through it.

Connectwell Lamp Test Diode Modules

PLC based control panels often need to be tested inside the assembly line to verify the logic built by the programmer. Connectwell Lamp Test Diode Modules are available in a range of configurations for control panel tests.

Individual Diode type

In this configuration, individual lamps can be illuminated with different inputs to the individual diodes. For example, to turn on the first lamp, the first switch needs to be turned on.

Common Anode / Cathode Diode type

By using a common anode or cathode diode modules, all the lamps can be turned ‘on’ at a time to test the outputs.
For common anode module, a positive signal needs to be supplied at A’ point and all the lamps connected to the 1, 2,3 up to 22 will turn on at one time.
For common cathode diode module, a negative supply needs to be supplied at ‘A’ point to turn on all the lamps.

Individual Diode for multiple signals

In some applications, multiple signals are available to turn on the same output. For such a configuration, I1 and LT1 are used to turn on the same output O1.

Common Anode /Cathode Lamp Test Module

Connectwell offers common anode modules and common cathode diode modules, with individual lamp tests modules as well single input for all outputs. Here the output can be turned ‘on’ by with a single input to an individual channel or a common channel, as per the requirement of the application.

Diode Test Module for AC supply

While the previous Connectwell Diode Module configurations are mainly for DC supply, Connectwell also offers a diode module for AC supply. In this configuration, the outputs can be turned on by individual signal and common signal.
