Overview
With an SDM-CD16ACA, your Campbell Scientific data logger can automatically activate external ac or dc devices such as motors, pumps, heaters, valves, and fans. This ac/dc relay controller has 16 ports for connecting your ac or dc devices. Each port can be controlled automatically by the data logger’s program or controlled manually with an override toggle switch.
The SDM-CD16ACA is a RoHS-compliant version of the SDM-CD16AC.
Key Advantages
Use multiple modules for up to 256 control ports
Technical Description
The SDM-CD16ACA has a toggle switch that provides three positions: ON and OFF for manual override, and AUTO for data logger control.
- In the ON position, the common (COM) and normally open (NO) contacts are closed.
- In the OFF position, the normally open contact is open.
- In the AUTO position, the state of the relay is controlled by the SDM command issued through the data logger’s control ports or SDM terminal.
SDM Operation
The SDM-CD16ACA is a synchronously addressed data logger peripheral. Data logger control ports 1, 2, and 3 are used to address the SDM-CD16ACA, then clock out the desired state of each of the 16 control ports. Up to 15 SDM-CD16ACAs may be addressed, making it possible to control a maximum of 256 ports from the first three data logger control ports.
Benefits
- Allows the data logger to automatically turn devices on or off when a threshold (for example, temperature or water depth) has been reached
- Addresses up to 15 SDM-CD16ACAs, allowing up to 240 ports to be controlled by one data logger
- Includes LEDs that indicate when a port is active
- Provides a manual override for each port
- UL/CUL approved product; RoHS compliant
