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?/SUP> 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 retransmission 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.
