Overview
The SDM-CD16D increases the number of digital outputs that can be controlled by a Campbell Scientific data logger. The SDM-CD16D is commonly used to drive normal logic level inputs.
Key Advantages
For low-power applications
Technical Description
The SDM-CD16D increases the number of digital outputs that can be controlled (i.e., set to 0 or 5 V) by a Campbell Scientific data logger. In addition to being able to drive normal logic level inputs, when an output is set HI, a boost circuit allows it to source a current of up to 100 mA for controlling low voltage valves, relays, or other devices.
Up to 15 SDM-CD16Ds may be addressed, making it possible to control a maximum of 240 ports from the first three data logger control ports.
Data Logger Connection
The SDM Jumper Wire Kit (pn 32505) connects up to four SDMs to the data logger. This kit is recommended when multiple SDMs are connected to one data logger or for extremely short distances between the SDM and data logger. The CABLE5CBL-L cable is recommended for connecting a single SDM to the data logger, and for longer distances between the SDM and data logger.
Benefits
- Intended for low-voltage, low-power applications not suitable for the SDM-CD16AC
