ETR-9090 1/16 DIN Microprocessor Based Smarter Logic® Temperature Control

48mm x 48mm - Dual Display - Smarter Logic for Superior Control - Selectable Input - Selectable Alarm Modes - °F or °C Display - Sealed Mylar Front Panel - External Lockout - All Control Parameters Adjustable from Front Panel -Automatic/Manual Mode Operation - 3 Year Warranty.

 

The ETR-9090 has been available for many years and is the workhorse of 1/16 DIN Microprocessor Based Controls. Using Smarter Logic technology, the ETR-9090 provides better than ever control results. SMT and microprocessor technology allows advanced features plus economy and reliability. All parameters are front panel configurable for easy set up. A ramp to set point function prevents rapid temperature changes that could damage the product being heated. The ramp function used with the dwell timer can provide two ramp and soak segments. The ETR-9090 in-panel depth is only 3-3/8". In use in a wide variety of industrial and commercial applications, the ETR-9090 is the control to rely on.


 

 

ETR-9300 1/16 DIN Microprocessor Based Smarter Logic™ Temperature Control

48mm x 48mm - Smarter Logic for Superior Control - NEMA 4X/IP65 Front Panel - Universal Sensor Input - Analog Input for Remote Set Point Adjustment - Second Set Point - Loop Break Alarm - Heater Break Alarm - Auxiliary 20VDC/25mA Power Supply - 10 per Second Sample Rate - 18 bit A/D Converter Digital Communications - Bumpless Transfer - UL / cUL, CSA , CE Agency Approvals - 3 Year Warranty.

 

The ETR-9300 with Smarter Logic offers extensive features that are rarely available on a 1/16 DIN control. With universal input, all thermocouple, RTD, voltage and current types can be selected from the front panel. A universal power supply along with a low voltage input option provides a wide operating range. An analog input allows the set point to be remotely adjusted. When the current drops below a specified minimum, an alarm condition signals a heater failure. Should a sensor break, a smooth, bumpless transfer is produced from automatic to manual control to restrict a drastic, possibly damaging change in output. Programmable secondary outputs provide a wide range of variations. Proportional cooling, latching and band alarms are among the many possible functions of the secondary outputs. Remote networking of multiple controls is available with the serial communications feature. An analog signal retransmits the process value to a chart recorder, data logger or PLC. The ETR-9300's front panel is NEMA 4X/IP65 rated for harsh environments and for applications requiring washing with a direct spray. The panel depth is only 3". OGDEN offers the best value on the most advanced features.


 

 

ETR-3400 1/32 DIN Microprocessor Based Smarter Logic® Temperature Control

24mm x 48mm - Smarter Logic for Superior Control - NEMA 4X/IP65 Front Panel - Universal Sensor Input - Analog Input for Remote Set Point Adjustment - Second Set Point - Loop Break Alarm - Heater Break Alarm - Auxiliary 20VDC/25mA Power Supply - 10 per Second Sample Rate - Selectable Set Point or Process Value Display - Bumpless Transfer - 18 bit A/D Converter - Digital Communications - UL/cUL, CSA. CE Agency Approvals - 3 Year Warranty.

 

The ETR-3400 Smarter Logic microprocessor-based control features a bright four digit LED display. Control and input parameters are selected with three touch keys. A unique function places 5 parameters in the beginning of the menu. The menu then can be configured for a specific application. Either the process value or the set point can be displayed. Like the ETR-9300, when the current drops below a specified minimum, an alarm condition signals a heater failure. Should a sensor break, a smooth, bumpless transfer is produced from automatic to manual control to restrict a drastic, possibly damaging change in output. Programmable secondary outputs provide a wide range of variations. Controlling processes such as pressure and flow are possible because of the fast sampling rate. Digital communications or analog re-transmission allow the ETR-3400 to be integrated with supervisory control systems and software, to drive remote displays, chart recorders or data- loggers. The panel depth is only 3-7/8". The ETR-3400 is a huge value in a very small package.


 

ETR-4100 ETR-8100 ETR-9100

ETR-4100, ETR-8100, and ETR-9100 Series - Auto-Tune PID Temperature Controller

Easy-to-Use Operator Interface - Fuzzy Logic PID Heat & Cool Control - Fast A-D Sampling Rate (5 times/sec.) - Universal Input PT100, Themocouple with High Accuracy 18-bit A-D - Analog Output (Linear Current or voltage) Uses High Accuracy 15-bit D-A - RS-485 or RS-232 Interface - Programming Port - Manual Control & Auto-Tune Functions - Six Alarm Mode Selections - Lockout Protection - Bumpless Transfer During Failure Mode - Soft-Start Ramp and Dwell Timer - Bright LED Display Stabilized with Digital Filter - SEL Function Allows User to Rearrange Menu - UL Recognized, CSA, IEC1010-1.

 

The ETR Fuzzy Logic plus PID microprocessor-based controller series incorporates two bright, easy-to-read, 4-digit LED displays, indicating process value and set point value. The Fuzzy Logic technology enables a process to reach a predetermined set-point in the shortest possible time, with minimum overshoot during power up or external load disturbance. ETR-9100 is a 1/16 DIN size panel mount controller. ETR-8100 is a 1/8 DIN size panel mount controller, and ETR-4100 is a 1/4 DIN size panel mount controller. These units are powered by universal 90-250 VDC/VAC supply. Up to three outputs are available for control and alarm. The second output may be used as cooling control, or an alarm. Output selections are relay, triac, 5 V logic output, linear current, or linear voltage to drive an external device. There are six types of alarms, plus a dwell timer may be configured for the third output. The units provide universal input selection of RTD’s and thermocouple types J, K, T, E, B, R, S, N, L without modification of the unit. The input signal is digitized by using an 18-bit A to D converter. Its fast sampling rate enables the unit to control fast processes. Digital communications RS-485 or RS-232 are available as an additional option. These options allow the units to be integrated with a supervisory control system and software. A programming port is available for automatic configuration, calibration and testing without the need to access the keys on front panel. By using proprietary Fuzzy Logic PID auto tuning technology, temperature overshoot and undershoot is minimized. Figure 1 control diagram is a comparison of a typical system response with and without Fuzzy technology.
