AD4RS: Measurement module with RS232 and RS485

Analog measurement module AD4RS is a four input A/D converter allowing you to measure up to four analogue signals 0-10V or 0(4)-20mA. Measured out values are send to a PC or other system by means of RS232 or RS485 line.

Default input range is 0-10V or 0(4)-20mA, but it ican be modidied to suit your application upon request. Please contact us to get a custom measuring range.

Features of A/D converter with serial lines

• Four analogue inputs for voltage or current
• Each channel can have different range (upon request)
• Measuring range split into 10 000 pieces
• Mesuring rate: twice in a second for each channel
• Communication via RS232 or RS485 line
• Spinel and Modbus RTU communication protocols (MODBUS documentation on request).
• Measuring software for watching and logging is supplied as a freeware
• Wide power supply voltage range: 7 - 30 V DC
• Measuring is based on a single multiplexed 16 bit sigma-delta A/D converter
