E5CS-Q1PX – A RELIABLE EQUIPMENT

E5CS-Q1PX is a 1/16 DIN sized temperature controller manufactured by OMRON, which offers selectable control and selection of various alarm modes. The key highlights that certainly mark OMRON temperature controllers as a preferred choice include, high accuracy in readings (to +- 0.5% of full scale), unmatched flexibility offered by multiple temperature scale ranges to match specific application requirements and selectable on / off and PID control with auto tuning facilities of proportional band. Also included in the set is the standard 8-fucntion alarm, easy to read 11mm high LED display, a nonvolatile memory backup and tamper proof settings, faulty sensor compensation and controller diagnostics. To further add, all these features are bundled together with a three-year warranty assurance.

The Unmatchable Self-Diagnostic Function

Given the mentioned features, E5CS-Q1PX can certainly be considered a reliable device. To further ensure secured usage, the temperature controllers of the E5CS-X series have an inbuilt self-diagnostic function that displays various error messages, in case of a technical issue, to facilitate easy troubleshooting.

For instance, a message FFF on the screen of E5CS-Q1PX indicates that either the temperature has risen beyond the temperature scale range or the Thermistor has been short circuit. Depending upon the cause statement highlighted, appropriate control output is initiated. In the specified case, if the temperature has risen, the control output is OFF during heating (reverse) operation and if the Thermistor has been short circuited, the control output function is ON during cooling (normal) operation. In various other situations, depending upon the requirement, the appropriate messages are displayed and if required, the control output disables the key operations.

UPG501B – A Handy Pre-Scaler by NEC

UPG501B, a NEC product, is a GaAs divide-by-4 pre-scaler that can be operated in a frequency range of 1.5 GHz to 5 GHz. It is a static divider with two master slave D type flip-flops and operates from a single supply voltage (+10 Volts). The key application of a UPG501B is in frequency synthesizers of microwave communication systems and measurement equipments. The manufacturers i.e. the NEC commits guaranteed performance over an ambient temperature range (i.e. from – 25oC to + 75oC) and provides the product in a reliable and easily usable hermetically sealed 8 – lead ceramic flat package.

Damage Prevention Guidelines

UPG501B is a handy electronic device and keeping few basic usage guidelines in the forefront, can help deal with any permanent damages to the product features. The supply voltage of 10V, for instance, is perfect for UPG501B. However in any circumstances must not be above +12V. Similarly, the supply current must not exceed beyond 150 mA and the total power dissipation rating can be at a maximum of 1.5W. The suggested operating temperature range is – 65oC to + 125oC. The storage temperature however, can go up to a positive temperature of 175oC, the minimum being - 65oC.

There are possibilities, when due to high internal gain and gain compression, UPG501B could end up in self-oscillation. The same can be managed by either adding a shunt resistor to the RF input line or by applying a negative voltage through a 1000-ohm resistor to the normally open VGG connection.
