A safety relay’s primary task is to monitor a safety system and either enable or disable that system, and then to provide a safe and reliable response if and when a dangerous (unwanted) condition occurs. Safety relays are simple devices designed to perform an equivalent function to an electromechanical relay, on a much larger scale. …
The safety relay is connected to the safety circuit using a variety of input devices to signal a hazardous condition, and the load contacts are used to connect to the power/control circuit being switched. It is a requirement that a safety relay must provide a manual reset for the return to the normal state, and …
A safety PLC is a specialised type of PLC designed to manage safety functions of a machine or process. Typical functions include E-Stop, safety gates, light curtains, two hand control, and various other input and output interlocks. The main difference between a safety PLC and a standard PLC comes down to the software and firmware …
Rechner is a distinctive German sensor company that has been in the sensor business for over the last 25 years. Since its inception, Rechner has become a leader in level control, a position it has maintained. However, over the last 5-10 years, Rechner has expanded its expertise into areas such as pressure sensing, flow sensing, …
A safety PLC may be defined as an industrial control system which places a high priority on the safety and integrity of the automation system, its data, and of the personnel and equipment that it is controlling. In many cases, a safety PLC is a programmed system where the functionality of a given application is …
A capacitive level sensor is a proximity sensor that is used to detect liquid levels, interface between liquids such as oil and water, or liquid and solid interface. They operate on the principle of capacitance whereby in the simplest form of a level sensor, a capacitor is formed with the vessel containing the material to …
Stober Gearbox with a flange block is designed to rigidly support the machine components with fixed bearings. The dimension between the mounting surface and output bearing fulfills pump industry standard,” said Frank Langro, President of Stober Drives, Inc. Although not new to the European market, adding the flange block to the gearboxes’ configuration provides European …
