Primary Current Injection Testers
Primary Current Injection Tester is designed for testing protective relay and circuit breakers and also testing the turns ratio of current transformers at high variable currents. A test current is injected into the primary side of a system to determine how the system behaves at particular levels of current. This test makes it possible to determine whether the relay will trip and how long the current needs to flow before the trip is initiated.

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.

C Series Current Output Module
The C Series Current Output Module features up to eight channels of simultaneous analog output. You can choose between enclosed and non-enclosed modules. Additionally, the C Series Current Output Module has built-in open-loop detection. This detection generates an interrupt in software when an open loop is detected, zeros outputs to ensure safety, and avoids driving actuators at system power-on. The C Series Current Output Module requires an external power supply and includes a channel-to-earth ground double isolation barrier for safety and noise immunity.The C Series Current Output Module includes the NI-DAQmx driver and configuration utility that simplify configuration and measurements. NI-DAQmx supports NI programming environments as well as Python, ANSI C, C#.NET, and MathWorks MATLAB® software.
