Define Instruments, a leader in industrial instrumentation, today announced the release of two products in it’s new family of multi-channel control stations for data acquisition (DAQ).

The Zen series brings together decades of DAQ technical knowledge and industry know-how resulting in robust and powerful units capable of tackling a range of heavyweight 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 units help solve this issue”, Afrogheh adds.

Zen series units have 16 channels and accept a "universal" set of analog inputs (thermocouple, RTD, mV, V, mA, frequency and counter). Units 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 acquisition and collation of multiple signals routed directly to a master console such as for connecting directly to SCADA systems and PLCs. It has four digital inputs and a RS485 Modbus/RTU port.

Additionally, it has an Ethernet port that can be selected as Modbus TCP, or Ethernet IP (ODVA conformant). It is available in both isolated and non-isolated options, the non-isolated option being a low-cost solution for RTD applications.

The Zen Data logger is appropriate for applications that require acquisition and visualization 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 visualization and graphing is accessed through Define Instruments free WorkBench software.

The entire Zen series product line (more will be released later this year) is programmed with the same WorkBench software, keeping things simple for industrial technicians.
