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 ...

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.

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.

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 ...

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 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.

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 ...

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).

The BusWorks 965EN Input Modules interface thermocouple and millivolt signals directly to an Ethernet Modbus/TCP 10/100 network.

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 ...

Designed to reduce the cost of an additional power supply, the VR6 Voltage Regulator easily snaps together with the PDS8 Dual Input Power Distribution Module via common standoffs saving valuable ...
