Using Liquid Level Control Relays

Tuesday, October 4, 2022

Using Liquid Level Control Relays Liquid Level Control Relays detect & control levels of conductive liquids such as fresh water, seawater, sewage & coffee.  They provide a low voltage signal (typically 5VDC pulsed to prevent electroplating issues) to a probe or probes and a common connection on the tank. The conductive properties of the liquid complete a circuit between a probe and the common connection when the liquid comes in contact with both. These relays sense the resis

INTRINSICALLY SAFE BARRIER RELAYS

Tuesday, October 4, 2022

Intrinsically Safe Barrier Relays Intrinsically Safe Barrier Relays protect hazardous location circuits and control loads without additional relays or contactors. IS circuits operate at low energy levels that cannot ignite potentially explosives atmospheres. In the event of a fault condition, these Intrinsically Safe Barrier Relays prevent excess voltage and current from reaching the hazardous area. When electrical equipment is used in, around, or near an atmosphere that has flammable gase

Understanding Time Delay Relay Functions

Monday, October 3, 2022

Understanding Time Delay Relay Functions Issue: What is the difference between On Delay, Off Delay, Single Shot, Interval On and all these other time delay functions? Solution/Resolution: Understanding the differences between all the functions available in time delay relays can sometimes be a daunting task. When designing circuits using time delay relays, questions such as what initiates a time delay relay, does the timing start with the application or release of voltage, when

Why Is Motor Control Important ?

Thursday, September 1, 2022

 Why Is Motor Control Important ? Motor control devices regulate how a motor works and controls them manually, automatically, or remotely to protect electrical motors against electrical overloading and surging. They can start, stop, and change the speed and rotation of motors. It can handle additional capabilities that regulate the direction and collect and log data. Industrial automation can involve motor control, variable frequency drives, human-machine interface, programmable logic co
