The XTA-120V-6 six-channel optocoupler is intended for use with control system digital input modules to monitor contact closures or mains power supply on-off voltage levels.

The I8 Input Bus Module provides eight Class-A supervised inputs. A total of eight input modules can be connected to one apC or apC/8X and a total of four input modules can be connected to one apC/L.

In this post we are reviewing the ESP-01 Wi-Fi Relay Module. It is one of the cheapest smart switches you can purchase currently for making smart home, internet of things, and other wireless do it ...

Providing eight SPDT, high-current Form C relays directly switching 6A loads at 250V ac and 100V dc, the Seal/O-520 relay and optically isolated input module also has eight nonpolarized inputs for ...

Higher amperage relay output modules and an 8-point input simulator module are now available from AutomationDirect for the Click series stackable micro brick PLCs.

Relay modules are input/output devices that mount on DIN-style rails. The rails typically reside in enclosures and hold controls for managing factories, buildings, and machines. As the space ...

A relay module is a piece of electrical equipment that provides protection and isolation to relays. Find out more about this board and the best manufacturers here.

The relay repeater module accepts single contact closure inputs from logic solver trip outputs including the company's STA Safety Trip Alarm and the SPA2 Programmable Limit Alarm Trip. With three ...

The 40-781A-92x (PXI) and 42-781A-92x (PXIe) modules consist of either a single or dual microwave changeover switch payload, capable of switching up to 110 GHz in 50 Ω.

Measuring just 6.2 mm thick, the flare series of DIN-rail mounted terminal block relay modules offer an extensive range of timing functions for industrial and process control ...

If the select is one, the “1” input routes to the output. Obviously, a relay with two poles can act like two gates (the input at the bottom has to be the same for both gates).
