SWB-2833, 4x71, 2 A, Electromechanical Relay Matrix Module for SwitchBlock
781421-33
4x71, 2 A, Electromechanical Relay Matrix Module for SwitchBlock - The SWB‑2833 is an electromechanical relay matrix card for SwitchBlock systems. Designed for high power, it can operate as an individual relay card or expand in a single carrier or single PXI chassis. You can connect any input to any output, individually or in combination. You can use matrix switches to route signals from oscilloscopes, DMMs, arbitrary waveform generators, and power supplies to various test points on a unit under test (UUT). The primary benefit of matrix switches is simplified wiring—the overall test system can easily and dynamically change the internal connection path without any external manual intervention.

AC Relays
The E-MAX ATR and ACV Relays are the AC equivalents of the industry standard E-MAX TIR Trip Indication Relays and AVR Auxiliary Voltage Relays. While the TIR and AVR Relays are designed for use in DC trip circuits, the ATR and ACV are designed for use in AC trip circuits. The relay outputs may be used to record breaker, relay, communication and control system operations, and to activate alarm and/or annunciator contacts. Relays do not require standby power to operate; they are powered by their inputs.

ARTES Automatic Relay Test Systems
The purpose of power system protection is to use accurate and reliable protection devices to detect faults promptly and without fail and to minimize impairments to the power supply by selectively switching off faulted sections of the system.The use of suitable protection devices can significantly improve the safety and reliability of complex electrical power systems and installations. Regular testing is the only way to ensure that these protection devices function correctly throughout their operational life.More than 20 years of experience in developing and manufacturing automatic relay test systems have gone into creating the third generation of ARTES test instruments. Back in 1996, KoCoS was the first company to present Windowsbased testing software for controlling and operating test equipment and the company continues to play a pioneering role in the design of clearly structured and ergonomic user interfaces today.
