Define Instruments, today announced the release of the first two products in it’s new family of multi-channel control stations for data acquistition.

The Zen series brings together decades of technical knowledge and industry know-how resulting in rugged and powerful units that are capable of tackling a range of hefty industrial monitoring and control applications.

Each of the Zen units has a narrowed scope of application to make it easier for consulting-specifying engineers to identify the unit that best matches their application needs.

“It’s predecessor had such a wide range of capabilities that customers had difficulty understanding whether it could cater to their specific requirements”, explains Define Instruments Business Development Manager Rolla Afrogheh.

“The narrower scope Zen series helps solve this issue.”, he concludes.

Zen series units have 16 analog inputs (thermocouple, RTD, mV, V, mA and frequency) and easily connect to commercial equipment such as HMIs via an RS485/232 connection or Ethernet connection.

The Zen RTU is ideal for applications which require collation of multiple signals routed directly to a master console such as for connecting straight to SCADA systems and PLCs. It has four digital inputs and one RS485 Modbus/RTU port. Additionally, it has an Ethernet port which can be selected as Modbus TCP or Ethernet IP (ODVA conformant). It is available as both isolated and non-isolated options, the non-isolated option being a low-cost solution for RTD applications.

The Zen Datalogger is appropriate for applications which require collection and visualisation of data from multiple sources. It has 2 analog outputs and 2 relay contact outputs for control and alarm applications. Data is logged on a 1GB micro SD card for high capacity logging and simple data log retrieval.

Data visualisation and graphing is accessed through Define Instruments free WorkBench software. The entire Zen series product line (more will be released later this year) is configured with the same WorkBench software.
