FAQs 6

What is a dry contact?

A dry contact (also known as a volt free contact or potential-free contact) is defined as a contact in which power / voltage is not directly provided from the switch but is instead always being supplied by another source. Dry contacts are known as passive contacts, as no energy is applied to the contacts.

How do dry contacts work?

Dry contacts function as simple ON/OFF switches, similar to a typical light switch, providing straightforward control. It operates like a controlled switch. It can be referred to as a secondary set of contacts of the relay circuit. It can be referred to as the primary set of contacts. Dry Contacts is used to provide isolation between devices.

What is the difference between dry contact and wet contact?

Dry contact is one in which the power is always being supplied by another source. Wet contact is one in which the power is being supplied by the same power source that the control circuit is used to switch the contact. Dry contacts function as simple ON/OFF switches, similar to a typical light switch, providing straightforward control.

Why are dry contacts used in plc modules?

Hence, dry contacts are mostly used because it provides complete isolation between devices. Dry contacts are used in PLC modules in which input voltage 24 V is provided to the input of PLC modules and output is provided with separate control voltage 5 V from the processor.

What is a dry contact relay?

A dry contact relay operates its contacts without needing voltage, allowing it to control circuits across any voltage level. The RIB series dry contact input relay uses different dry contacts such as switches, thermostats, relays, and solid-state switches, etc.

What is a high frequency inverter?

In many applications, it is important for an inverter to be lightweight and of a relatively small size. This can be achieved by using a High-Frequency Inverter that involves an isolated DC-DC stage (Voltage Fed Push-Pull/Full Bridge) and the DC-AC section, which provides the AC output.
