Current Digital Set Point Relay
These Digital set point relay for current (type mrd2011-a) are field proven with excellent sensitivity and are with two independent outputs and are used as under current and over current controlling operations. The two independent outputs are programmable in a specific range i. E. The range if it is 25a the settings can be made within the range of 250 a. This facility of having the liberty to set the required current is added advantage in the digital meters of these models available in the market. The set points are field settable within the range mentioned in the model. these relays have inbuilt timers and this facility enables the user to avoid external timers and external wiring. The timers are programmable from 0 second to 20 seconds. The ranges available are up to 2500 a. The dimensions are compact and are of 96 mm x 96 mm x 65 mm only. The auxiliary supply for the relay is 110v ac or 230v ac.

40 Channel Low Thermal Relay Multiplexer Module
DP-cPCI-4017
DP-cPCI-4017 is a 40 Channel Relay Multiplexer module constructed using ‘2 Form A’ relays. The DP-cPCI-4017 is implemented as a 6U cPCI module. As a 40 channel multiplexer, one input can be multiplexed to any of the forty outputs or vice versa. The forty channel multiplexer is divided into 4 banks of 10 channels each. This combination allows the board to be used as one group of 40x1 or two groups of 20x1 or four groups of 10x1 multiplexer. The banks are isolated from each other using tree switches. Four tree switches are used, one tree switch for each bank.

80 Channel Relay Multiplexer
DP-VXI-4017
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.

Monitoring Relays
A Monitoring Relay is a protective control device. The basic functions are to receive input signals, monitor and determine them, and output an alarm signal if a set value (threshold) is reached. Monitoring Relays monitor power supplies (voltage, current, power, phase), temperatures, and other analog signals and detects abnormalities in machines and equipment by determining values against alarm thresholds.

Acoustic Compound Protection System
ACOMPRIS
Static kind of infrastructure is often vulnerable to attacks by either small arms fire (SAF) or mortars. The objects could be for instance a military forward operating base, an embassy or a post from the United Nations. As attacks may occur all the time, persistent and affordable protection is required. Especially when inhibited by civilians, ease of operations use and maintenance become more important. Often installed in remote places far away from the electricity grid, power consumption is an issue.
