0-999,9Ω Programmable resistor decade board with step of 0,1Ω and Maximum power rating up to 10W
- The device can be adjusted to desired resistance value by 8 digital inputs (5V logic levels, maximum 24V). It is possible to use a microcontroller, such as Arduino. In the photos, you can see the product connected to National Instruments VirtualBench (not included with the product. We can send you a compatible LabVIEW application for control via PC for FREE upon request.)
- Easy mounting on DIN rail racks with integrated mounting system.
We specialize in custom electronics development. If you need a variation of this product or would like to have the programmable resistor decade board integrated in a larger device, please contact us.
Basic price: 20.000DKK excl. VAT

Output resistance (J1)
Resistance between J1 terminals is calculated as: Rtot = V x 100R + X x 10R + Y x 1R + Z x 0,1R
|Maximum power rating for 100R, 10R, 1R decades||10W|
|Maximum power rating for 0,1R decade||2W|
|Maximum current through J1 - Constant Resistance||2,5Arms|
|Maximum current through J1. Resistance is switched||1Arms|
|Maximum voltage between J1 terminals and GND||230Vrms|
|Power supply J2||24VDC +-5%, max. 200mA|
|Control signals J3. Nominal input voltage||5V logic level. 22kΩ pull up to 5V|
|Maximum input voltage||24V. Iin @24V 1,7mA|
|Cooling fans start temperature (board surface)||~70oC|
|Maximum ambient temperature||40oC|
|Mounting||DIN rail 32/35|
|Dimensions l x b x h(above DIN rail)||403 x 126 x 69 mm|
The decade board should be placed with adequate space around, bearing in mind that the total power dissipation can reach 20W.

LEx = HI: Latch is transparent. Multiplier follows address.
LEx = LO: Multiplier is locked to address present in the moment LEx is set LO.
