The MicroDAQ SRL-26 is a multi-function analog and digital I/O product which communicates to the host PC via an RS-232 or RS-485 serial interface. The unit has a 14-bit resolution and is the perfect measurement device for portable, laboratory or classroom use.

Featuring 16 analog inputs, the unit can be used to measure voltage signals from sensors, transducers, accelerometers and much more. The digital I/O is available in 3 sets of 8 channels which can be programmed as inputs or outputs.

Two interface versions are available for the serial MicroDAQ range, these include RS-232 models and RS-485 models. The RS-232 models are best suited for short distances (up to 30 meters). The RS-485 models allow for long distance data transmission (up to 1200 meters). These RS-485 models are ideally suited for process control applications in a plant or industrial environment, which require long cable runs.
