Omron has extended its 1/32 DIN range of intelligent controllers, to offer three models which provide higher degrees of functionality and flexibility, and superior visibility, in a highly compact, cost-effective package. The range now includes a temperature controller and a counter/timer along with the existing 'smart' panel meter/tachometer. All three devices have been designed to be simple to configure and use, and feature an inbuilt RS485 communications option for ease of integration.

The E5GN temperature controller provides a range of control options, including heating and cooling, heating only and cooling only, with the choice of either on/off or PID control.

Output options include relay, voltage or a combination of the two.

The relay outputs can be configured as alarms, or alternatively alarm signals can be transmitted over the RS485 interface.

The E5GN has been designed to accept a wide range of inputs, covering all standard thermocouples, PT100 RTDs, analogue sensors and non-contact signals.

PT100 RTDs can take advantage of a three-wire input for added accuracy.

The H8GN counter/timer combines multi function counters and timers in a single, compact, cost-effective unit.

The H8GN can operate in a number of modes, including a new 'on/off duty adjustable recycle' mode which gives on and off times as a percentage of the total set time, and a range of outputs includes an SPDT, 3A-rated relay.

The displayed values can be scaled to read counts in engineering units.

Individual inputs for count 1, count 2 and reset are provided when the H8GN is working in counter mode, or for start, gate and rest when it is working in timer mode.

Multiple setpoint banks can be stored on-board, so that changing set-ups between different products is quick and simple.

Completing the range is the original and innovative K3GN 'smart' panel meter, offering users a high degree of functionality and intelligence for applications that need a level of sophistication yet which don't warrant the added cost of a full specification PID controller.

The K3GN provides an analogue DC voltage/current input, an open collector input and a non-voltage input, suiting it to use as a process meter, and also provides a 5kHz (max) pulse input, enabling it to be used as an RPM meter/tachometer.

The inputs can be scaled to read in engineering units, and the display can also be held at its current value or forced to zero.

A choice of either two relay or three transistor outputs is provided, which can be configured to give high, low and high-low pass levels.

The five-digit display can be configured to change colour when an event occurs or to signify different inputs.

Each controller has a high visibility display, which employs a high contrast, backlit LCD, and is easy to view at virtually any angle and from some distance.

The display colour can be set to red or green as preferred.

A key feature of the controllers is the ease with which they can be configured, either from the front panel using a menu driven system, or remotely from a PC via the RS485 interface.

The three units share a common front panel design and the same high clarity display, making the use of combinations of the three devices as aesthetically pleasing an option as it is space-efficient and cost-effective.

For use in arduous areas, the front panel of the controllers is sealed to IP66 NEMA 4X.

They are CE marked for conformity with all relevant EN/IEC standards, and are UL, CSA and VDE approved. Request a free brochure from Omron Electronics....
