Output-Low: Causes the control current to flow which turns on the relay.

To control an SSR in the sinking configuration as shown above, the two important states are: Relay Connections (Sinking Control, High-Side Load Switching) This is known as “sinking configuration” and essentially inverts the logic necessary to control the relay.įigure 1.

The best way to control relays is to connect the positive control terminal of the SSR to the LabJack’s VS (~5 volts) terminal and connect the negative control terminal to a digital I/O pin. This being known, most solid-state relays (SSRs) can still be controlled directly by the digital I/O.

The important detail to note is that all of the digital I/O lines on a LabJack have series resistance that restricts the amount of current they can sink or source. With the DACs you would typically use a sourcing configuration (DAC/GND) rather than sinking (VS/DAC).Ĭontrolling standalone relays using solely digital I/O requires a little more attention to details, but is still very easy. They can source enough current to control almost any SSR and even some mechanical relays, and thus can be a convenient way to control 1 or 2 relays. Per the specifications in each devices datasheet, the DACs can generally source more current that digital outputs.

Please see the RB12 datasheet for more details. If you buy an RB12, you will have to purchase the relay modules separately. The PS12DC tops out at 1.5A, but some modules that are compatible with the RB12 are rated up to 3.5A. The RB12 is a good option for controlling up to 12 loads with high voltage (AC or DC) and/or high current. Please see the PS12DC datasheet for details. In some cases, the relay itself isn't even needed since the PS12DC can switch power (up to 28V, 750mA) directly. The PS12DC provides 12 high-side switches that can source 5V from the LabJack or control any DC voltage up to 28V provided by your external supply. You can get 5V from the LabJack and control that with the LJTRD, but if your relays require a different control voltage you will have to provide that. Each LJTRD provides 2 low-side switches that can hold off up to 50V (DC only) and pass up to 200mA, so it can control almost any mechanical or solid-state relay. Students find the equipment easy to use and quickly learn to perform experiments.An LJTick-RelayDriver is a low cost option for controlling relays. Since data can be collected quickly, students spend more time observing phenomena and interpreting and analyzing results. Students obtain immediate feedback, because the equipment produces real-time graphs during data collection.

The hardware and software simplify the data-collection process and free the student from the time-consuming work associated with collecting large amounts of data. In either case, multiple sensors can be used simultaneously. With the Universal Lab Interface and a Motion Detector, students can collect distance, velocity and acceleration data. With either interface, students can easily measure physical quantities such as temperature, pH, pressure, light, dissolved oxygen, relative humidity, etc.

This program works in combination with Vernier Software's Universal Lab Interface or Serial Box Interface. Logger Pro software provides an inexpensive, user-friendly way for students to collect and analyze data with computers.
