Acces I/O Products has announced the Model WWP-IIRO-8 as a new addition to its line of wireless data acquisition (DAQ) products.

The product features a pair of intelligent 16-channel digital I/O units that communicate directly with each other.

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, NEMA 4 enclosures, which make them ideal 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 seven miles line-of-sight via a 900MHz wireless connection (up to 20 miles with optional high-gain antenna).

The eight isolated inputs can be driven by either DC sources of 3-31V (or higher by special order) or AC sources at frequencies of 40Hz to 10kHz and are not polarity-sensitive.

The WWP-IIRO-8 is useful for monitoring controllers and equipment status without needing an available auxiliary contact.
