ACCES I/O Products has announced an addition to its line of wireless data acquisition products - Model WWP-IIRO-8. This product features a pair of intelligent 16-channel digital I/O units that communicate directly with each other. Each unit contains 8 Form C (SPDT) electromechanical relays and 8 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; perfect 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 7 miles line-of-sight via a 900MHz wireless connection (up to 20 miles with optional high-gain antenna). The 8 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. Just connect the contactor coil, or other monitoring point, across the input and that's it. Whenever the coil is energized the input is on. For dry-contact monitoring applications, simply wire the power supply voltage into the switch circuit.

A microcontroller gives the WWP-IIRO-8 the capability and versatility expected from a modern, stand-alone, distributed control system and allows custom firmware useful for a variety of OEM products.

No software is required. The WWP-IIRO-8 was designed to work without the need of any additional software. No PC connection is required! Simply connect the supplied power supply, wire via the removable screw terminal board provided, and operate.
