A Thermoelectric device for measuring temperature, consisting of two wires of different metals connected at two points, a voltage being developed between the two junctions in proportion to the temperature difference.
A Timer which counts upwards from zero for measuring elapsed time is often called a stopwatch, a device which counts down from a specified time interval is more usually called a timer.
The AC drive industry is growing rapidly and it is now more important than ever for technicians and maintenance personnel to keep AC drive installations running smoothly.
Industrial control system (ICS) is a general term that encompasses several types of control ... smaller control system configurations such as programmable logic controllers (PLC) often found in the industrial sectors and critical infrastructures.
Three phase Solid State Relays (SSRs) have been available since shortly after the introduction of Single Phase SSRs in 1970. The first of these relays were nothing more than 3 individual SSRs with a common input connection packaged in a single housing.
A (SSR) is an electronic switching device in which a small control signal controls a larger load current or voltage. More. The relay may be designed to switch either AC or DC to the load.
In an electric power system, switchgear is the combination of electrical disconnect switches, fuses or circuit breakers used to control, protect and isolate electrical equipment.
A solid-state relay (SSR) is an electronic switching device that switches on or off when a small external voltage is applied across its control terminals.
