The SDM-SIO1A is a serial I/O expansion module for Campbell Scientific data loggers. It is designed to add an additional RS-232, RS-422, or RS-485 (half- or full-duplex) serial port to an SDM-capable...read more
The SDM-SIO4A is a serial I/O expansion module for Campbell Scientific data loggers. It is designed to add four additional and individually configurable and addressable RS-232, RS-422, or RS-485 (half...read more
The MD485 is an intelligent RS-485 interface that permits a PC to address and communicate with one or more data loggers over a distance of up to 1200 m. This interface also supports data-logger-to-dat...read more
The LLAC4 is a small peripheral that you can use to increase the number of low-level ac signals that your data logger can monitor. The LLAC4 is often used to measure up to four anemometers, and i...read more
Your data logger can measure more switch closures or voltage pulses with an SDM-SW8A. Sensors that output a switch closure or voltage pulse signal include tipping bucket rain gages, flow meters, and a...read more
The SDM-CAN allows a Campbell Scientific data logger to sample data directly from a CANbus communication network. This allows testing and verification of CANbus-based data alongside measurements made...read more
