INTERFACER–ADR1-SMT. Adjustable voltage/current sensitive relay control Board.

The INTERFACER-ADR1 board is designed to perform relay switching function based on two set points voltages or currents level "PICK UP" and "DROP OUT" 

1. Differential voltage set point

2. Trip set point

The board can accommodate three industrial inputs configurations:

1. Input current 4-20mA (or 0-20mA)

2. Input current 1-5mA (or 0-5mA)

3. Input current 10-50mA (or 0-50mA)

4. Input voltage 0-5VDC

5. Input voltage 0-10VDC (or custom see Application note #108)

6. Input voltage 0-15VDC

7. Input voltage 0-20VDC

8. Input voltage 0-30VDC

9. Input voltage 0-60VDC

Shown above SMT version with two with two adjustable multi-turn trimmer (option) Input set to 0-10V DC

If used properly, it will eliminate the need for expensive boards, which would otherwise be needed to carry out the same tasks.

The INTERFACER-ADR1-SMT is easy to install, setup and operate. If you want to do professional relay switching via setting of voltage or current, The INTERFACER-ADR1-SMT offers the features you need.

As mentioned above, the board can be configured to accept input signals of 0-60V, 0-30V, 0-20V, 0-15V, 0-10V, 0-5V or 1-5mA, 4-20mA or 10-50mA.

Mounted easily via four 0.125" mounting holes.

Setting the board is simple Just follow these easy steps

1. Connect the board to 24VDC or 24VAC or 28VDC or 28VAC

2. Set the board via jumper provided to the desired input configuration (10V, 5V or 4-20mA).

3. Connect your voltage or current signal to the input. Set the reference point until relay turns on (LED will light up).

4. Adjust the input signal to the desired trip out point. 

5. Adjust the span trimmer until the relay turns off. 

The board remembers input setting points and the relay will turn on and off based on them. 

The board is ideal when an analog signal is required to switch two position loads i.e. circulating pumps, recalculating fans, high and low fan speeds, humidifiers, pool chlorine feeding pumps, sensor level switching functions, differential switching controls, analog signal to relay on/off, analog signal voltage or current alarms and more.
