232M200 Series RS-232 Data Acquisition and Digital I/O Modules

RS-232 Data Acquisition ModuleThe 232M200 series of data acquisition models from Integrity Instruments is our mid-range line up. This series is an easy-to-use data acquisition module with 2 high accuracy A/D inputs and 2 D/A outputs. The 232M200 series uses an industry standard RS-232 interface. It has 8 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.

• 2 channels of 12-bit analog inputs (unipolar 0 to 5 Vdc)
• 2 channels of 12-bit analog outputs (0 to 5 Vdc)
• 8 configurable digital I/O lines
• One 32-bit pulse counter digital input
• One PWM output
• Baud rate: 9600, 19200, 57.6K and 115.2K
