RLL – a base

Relay Ladder Logic describes the functioning of the hardware in a simple form with effective representation of input , outputs. The basic Ladder is what the RLL in which the logical operations can be done with ease and can be debugged well with the required I/O’s. The amount at which inputs are connected to the…

Why Positioners for Control Valve

MINIMIZING FRICTION Positioners minimize friction effects of valve stem packing and the resulting hysteresis. This is especially beneficial for high temperature packing materials like graphite. INCREASES USAGE OF 4-20 mAELECTRONIC SIGNALS I/Ps can be located in the positioner that is on the valve. ACCURACY Positioners allow for fine control with better resolution and accuracy through…

SMPS – The converter

Switched Mode Power Supply is the source for many applications with required level of voltage configurations. One big level to another smaller one is the major aspect with an SMPS. A switched-mode power supply (SMPS) is an electronic circuit that converts power using switching devices that are turned on and off at high frequencies, and storage…

A system on a chip(SoC)

A system on a chip or system on chip (SoC or SOC) is an integrated circuit (also known as an “IC” or “chip”) that integrates all components of a computer or other electronic systems. It may contain digital, analog, mixed-signal, and often radio-frequency functions all on a single substrate. SoCs are very common in the…

Optocoupler – the isolation.

On considering the level of high to low voltage circuits as well as vice versa, the isolation is prior since the over surges may affect the performance. Optocoupler(optical isolator) is a combination of two devices to perform a transmission of light signals.The main function of an opto-isolator is to block such high voltages and voltage…
