485M300 Series RS-232 Data Acquisition and Digital I/O Modules

RS-485 Data Acquisition ModuleThe 485M300 series of data acquisition models from Integrity Instruments is our top end line up for multi-drop RS-485 communications. This series features an easy-to-use command set with 8 high accuracy A/D inputs and 2 D/A outputs. The 485M300 series uses an industry standard RS-485 interface. It has 16 digital inputs configurable separately as digital input or digital output. The module also features a 32-bit pulse counter input and pulse width modulation (PWM) output for driving devices such as electrical motors.

• 8 channels of 12-bit analog inputs (single ended & differential, unipolar 0 to 5Vdc & bipolar -5Vdc to +5Vdc analog input)
• 2 channels of 12-bit analog outputs (0 to 5 Vdc)
• 16 configurable digital I/O lines
• Digital I/O is compatible with our Opto-22 expansion board (link to EXP and Opto-22 modules)
• One 32-bit pulse counter input
• One PWM output
• Baud rate: 9600, 19200, 57.6K and 115.2K
