HOBO RXMOD-A1: 4-Channel Analog Module

An optional analog module with four analog inputs that support excitation power, scaling, and statistics measurements. These four, single-ended sensor inputs are configured through HOBOlink. A HOBO RX3000 is required for this product.

Key Features:

• 15-bit resolution and high accuracy
• Each module can have its own logging rate
• Input ranges up to 33V

Important Information: This product requires an RX3000 Remote Monitoring Station.
