概要
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.
続きを読む利点と特徴
- Intended for low-voltage, low-power applications not suitable for the SDM-CD16AC

詳細
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.

Data Logger Considerations
Up to 15 SDM devices can be connected to a single data logger. To communicate with connected SDM devices, the CR3000 and CR5000 use the SDM-C1, SDM-C2, and SDM-C3 ports. The other data loggers use ports labeled C1, C2, and C3. The 21X also requires channel 1H.
Programming
The SDMCD16AC Instruction controls SDM-CD16D operation in CRBasic. Edlog Instruction 29 controls SDM-CD16D operation in the CR7, and Edlog Instruction 104 controls SDM-CD16D operation in the CR10(X), CR23X, and 21X data loggers.
Power Considerations
The maximum output current that the SDM-CD16D can source is 400 mA. The power requirements are large compared to most Campbell Scientific products when driving significant loads. For many applications, an external rechargeable power supply is recommended to power the SDM-CD16D. This power supply should share a common grounding point with the data logger. For some applications, the data logger's sealed rechargeable battery may suffice; in this case, float-charging the batteries from an ac source is recommended.
Enclosure Considerations
The SDM-CD16D requires a desiccated, non-condensing environment; a Campbell Scientific enclosure is recommended. Grommets and screws are provided to attach the flanges/bracket to the backplate of our enclosures.
