DAX6500
2.4 GHz discrete/Analog I/O Extender
(the DAX6400 900MHz version is also available )

The Data-Linc Group DAX6500 I/O extender offers the ability to transmit discrete and analog signals with robust, industrial wireless technology. This allows wireless I/O communication between the Master and one or more Remotes from a few feet to many miles with applications in many industries. For added convenience, any unit may be configured as Master, Remote, Repeater or Repeater/Remote. This not only simplifies replacement but also reduces the number of units needed for “spare” inventory. A further convenience is the use of pluggable terminal blocks. If a unit needs to be replaced, unplug the terminal block with all its connecting wires and simply plug it into the replacement unit, eliminating the need to reconnect each individual wire.

The DAX6500 offers 12 bit analog resolution for enhanced accuracy and resolution of the analog channels. It therefore provides more precise monitoring and control, allowing data collected at the input to be relayed and reported with greater accuracy to the Master. For confidence in the wireless network’s performance, the DAX is capable of utilizing Data-Linc’s powerful, proprietary LincView^TM OPC RF network diagnostics and management software (see LincView OPC data sheet for information).

Each DAX6500 has a total of 24 independent points— eight discrete inputs and eight discrete outputs, as well as four analog inputs and four analog outputs. The SRM6x20 radio component reliably relays data even in harsh industrial environments. But in the event of a communications failure, the output states of the discrete and analog channels can be configured to retain the last known value or a pre-defined state.

The DAX6500 is ideal for fixed or mobile installations. Its wireless component combines the analog and discrete I/O extender with Data-Linc Group’s SRM industrial grade license-free wireless modems. In addition to the DAX6500 2.4 GHz (up to 10 miles, 16 km with LOS) and the DAX6400 900 MHz versions, the DAX/EXP expansion non radio Remote is also an option. The result is a simple to implement solution for wireless I/O signal transmission that ensures solid performance and reliability in any RF or wire environment. It is also ARRA compliant.
