Part No. E3P2G -
Teledyne Defense Electronics Relays & Coax Switch
The E3P2G series, three-phase solid state relay is the 2nd generation of the discontinued E3P series. The new design incorporates a high efficiency back-to-back thyristor with direct copper bonding for a longer lifetime expectancy. Over-Voltage protection is provided internally with TVS diodes for the input and output. Additionally our -16 model is designed with an RC snubber and VDR for greater protection to the output to handle all types of loads. The industrial SSR utilizes optical isolation to protect the control from load transients for each phase and has tight zero-cross window for low EMI. A control status LED are standard on all models.Available options include:E3P48D25 Load: 25A, 24-600Vrms ; Control: 4-30Vdc E3P48D50 Load: 50A, 24-600Vrms ; Control: 4-30Vdc E3P48D75 Load: 75A, 24-600Vrms ; Control: 4-30Vdc E3P48D75-16 Load: 75A, 24-520Vrms ; Control: 4-30Vdc ;E3P48D75-16 RC+VDR Output Protection

KoCoS Messtechnik AG
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.

DT2 -
North Atlantic Industries
The DT2 module features 16 independent, isolated, programmable channels that can be used for input voltage measurements (±80 V), or as a bi-directional current switch (up to 500 mA per channel). When programmed as a switch with the switch closed, both the current through the switch and the voltage across the switch can be monitored. These modules include diode clamping on each channel. Clamping is useful for inductive loads, such as relays and short circuit protection.

DP-VXI-4017 -
Data Patterns Pvt. Ltd.
DP-VXI-4017 is an 80 Channel Relay Multiplexer constructed using ‘2 Form A’ (DPST) relays. It is a ‘C’ size 1 slot register based VXI module. This 80 Channel Relay Multiplexer module is highly configurable. As an 80 channel multiplexer, one input can be multiplexed to any of the 80 outputs or vice versa. The 80 channel multiplexer is divided into 8 banks of 10 channels each. This combination allows the board to be used as one group of 80x1 or two groups of 40x1 or four groups of 20x1 or eight groups of 10x1 differential multiplexer. The banks are isolated from each other by tree switches. 8 tree switches are used, one tree switch for each bank. A common tree switch is used to group all the eight banks. For short circuit protection resistors are provided for all the common terminals.

Post Glover
The main purpose of a Neutral Grounding Resistor (NGR) is to limit the fault current present in a single line to ground fault. Limiting the possible current that can flow in such an event not only reduces damage to equipment but also helps safeguard personnel in the vicinity. Depending on the design of the resistor, this current value can be either high or low, continuous or of a predetermined duration. The resistor’s designed maximum current allows relays and protection settings to be easily determined and enacted, creating a safe work environment.
