Wireless I/O modules

The Interworld Electronics Model WWP-IIRO-8 features a pair of 16-channel digital I/O units that communicate directly with each other via a 2.4 GHz wireless connection.

Each unit contains eight Form C (SPDT) 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 this solution is completely self-contained and operates autonomously.

The units are packaged in small, rugged, NEMA4 enclosures suitable for remote installations in harsh atmospheric, industrial or marine applications. This product offers a low-cost alternative to costly signal wire installations in applications such as agricultural and irrigation systems, building management and control, security, and factory automation.

The units can operate at distances up to 5 km line-of-sight and greater distances are possible with an optional high-gain antenna. The eight isolated inputs can be driven by either DC sources of 3-31 V or AC sources at frequencies of 40 Hz to 10 kHz and are not polarity sensitive. The WWP-IIRO-8 is useful for monitoring controllers and equipment status without needing an available auxiliary contact.

A microcontroller gives the WWP-IIRO-8 the capability and versatility expected from a modern, standalone, distributed control system. Custom firmware can also be installed for OEM applications. OEM versions can also be supplied without the NEMA4 enclosure.
