With an SDM-CD16S, your data logger can control dc devices that have a relatively high-powered load, such as solenoids, solenoid valves, dc motors, stepper motors, lights, horns, heaters, and fans. With a voltage range of up to 48 Vdc and a maximum current output per channel of 2 A, the SDM-CD16S can drive up to 100 W of power on each channel.
Read MoreThis relay driver provides 16 dc voltage outputs that can be switched on and off manually or under data logger control. The SDM-CD16S's toggle switch has three positions: MANUAL, OFF, and AUTO.
单独的输入power-to-outputs (48 Vdc的格言um) and power-to-SDM-CD16S logic (7 to 48 Vdc) allow the option of powering the logic from the data logger’s 12 V while switching a higher voltage.
The SDM-CD16S is a synchronously addressed data logger peripheral. Data logger control ports 1, 2, and 3 are used to address the SDM-CD16S, then clock out the desired state of each of the eight control ports. Up to 15 SDM-CD16S devices may be addressed, making it possible to control a maximum of 256 ports from the first three data logger control ports.
The CABLE5CBL-L is recommended for connecting the module to the data logger. A 1-ft cable length should be sufficient when both data logger and SDM-CD16S are housed within an ENC12/14 enclosure; a 2-ft length may be required if the data logger and SDM-CD16S are housed at opposite ends of an ENC16/18 Enclosure. The cable length should be as short as possible. Typically, the maximum cable length is 20 ft. Contact Campbell Scientific if the length needs to be longer.

The SDM-CD16S 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.
The SDM-CD16S power requirements may be large compared to most Campbell Scientific products. For most applications, an external power supply is recommended to power the SDM-CD16S.
For some applications, it may be convenient to use the data logger’s sealed-rechargeable battery. If the data logger’s rechargeable batteries are used, the batteries need to be float charged via a wall charger or solar panel. The current available from the wall charger limits the SDM continuous output current. Campbell Scientific does not recommend using the data logger’s alkaline power supply.

Yes. Each of the channels on the SDM-CD8S and the SDM-CD16S has a manual control switch. Place the SDM-CD8S or SDM-CD16S into manual control by switching theManual Controlswitch to theOnposition. Now each channel can be turned on or off using its respective switch.
The SDM-CD8S and SDM-CD16S were specifically designed to switch solenoids (inductive loads), similar to those found on valves. The diode, to protect against voltage kickback, is built into the device. The SDM-CD16AC, however, does not have this diode.
No. The SDM-CD16S was designed to switch dc loads (7 to 48 Vdc; 2 A maximum per channel). The load power is isolated from the logic power (12 Vdc).
To switch an ac load, consider using an SDM-CD16AC.
The following relay devices can be used with the CR800 and the CR850:
The CR800 and the CR850 can also be used with a wide variety of third-party relay devices.
*Because the CR800 and the CR850 only have four digital ports, they do not have the ability to switch all six of the relays on the A6REL-12.
Yes. SDM devices are addressable. Multiple SDM devices can be connected to a data logger, as long as they all have a unique SDM address. Valid addresses are 0 through 15. Address 16 is reserved for SDM devices that support the Group Trigger Command. The address is set using the rotary switch on the face of the SDM-CD8S or SDM-CD16S.
