The SDM-CD8S adds capability to a datalogger by controlling dc devices that have a moderate current load, such as solenoids, solenoid valves, dc motors, stepper motors, lights, horns, heaters, and fan...read more
The SDM-CD16S adds capability to a datalogger by controlling DC devices that have a relatively high-powered load, such as solenoids, solenoid valves, DC motors, stepper motors, lights, horns, heaters,...read more
The SDM-IO16A has 16 ports that expand the digital input and/or output capability of Campbell Scientific data loggers. This module offers similar functionality to the control ports of the majority of...read more
The SDM-AO4A module increases the number of continuous analog outputs available to a datalogger. These outputs are used for proportional control or driving strip charts.read more
The LR4 relay module is useful in situations where the power is unreliable or where power needs to be conserved, because it does not need electricity to keep the relay closed. The state of the relay c...read more
