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 physical quantity. 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 bias 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 the meters, and it is convenient to realize multiple displays.Model standard version: HXDSBOXAH-:With RS485 version: HXDSBOXA-485:With relay output version: HX BOXAI-RLStandard version and version with RS485, rated power supply voltage range: DC6~25V, power consumption: 24V/40mA: with relay output version, rated power supply voltageRange: DC8~25V, power consumption: 24V/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.
