Optically isolated wireless relay

The WWP-IIRO-8 data acquisition wireless relay modules feature a pair of intelligent 16-channel digital I/O units that communicate directly with each other via a 2.4 GHz wireless connection of up to 5 km line-of-sight. Each unit contains eight electromechanical relays and eight optically isolated digital inputs.

When an isolated input is toggled on one of the units, it will cause the corresponding relay to switch on the other unit. No software or PC connection is required as the solution is completely self-contained and operates autonomously.

The units are packaged in rugged enclosures suitable for remote installations in harsh atmospheric, industrial or marine applications, offering an alternative to wired installations in applications such as agricultural and irrigation systems, building management, security and factory automation.

The eight inputs can be driven by 3-31 VDC or AC sources at frequencies of 40 Hz to 10 kHz.
