1. The meter can be called a universal analog input display meter. It can be matched with various sensors with analog output to display the actual . Such as temperature transmitter, frequency converter, motor speed, pressure, liquid level, concentration, etc.2. The instrument supports current input or voltage input.3. Default adaptation: 0-10V, 2-10V, 0-20mA, 4-20mA. By setting the parameter and gain parameter, it can adapt to other inputs in the range of 0-10V, or 0-20mA.4. It is displayed as a percentage by default. You can also set your own display range through F0-2 - F0-4.5. The instrument with 485 interface has already supported the communication between , and it is convenient to realize multiple displays.Model standard version: HXDSBOXAH-:With RS485 version: HXDSBOXA-485:With relay output version: BOXAI-RLStandard version and version with RS485, rated power supply voltage range: DC6-25V, power consumption: 24V or 40mA: with relay output version, rated power supply voltageRange: DC8-25V, power consumption: 24V or 50mA: power supply anti-reverse connection and surge protectionColour:grayMaterial:plasticSize:79 x 43 x 25mmPackage Contents:1 x Digital display meterOnly the above package content, other products are not included.Note: Light and different displays may cause the color of the item in the picture a little different from the real thing.
