SDM-CD16S 16-Channel Solid-State DC Controller

THÔNG TIN SẢN PHẨM

Overview

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.

Benefits and Features

Allows the data logger to automatically turn devices on or off when a threshold (for example, temperature or water depth) has been reached
Provides a manual override
Includes LEDs for a visual indicator of active outputs
Drives up to 100 W of power on each channel

Detailed Description

This 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.

In the MANUAL position, outputs are controlled by the position of the individual rocker switches.
In the OFF position, all outputs are off.
In the AUTO position, the state of the relays is controlled by the SDM commands from the data logger or by the logic control inputs.

Separate inputs for power-to-outputs (48 Vdc maximum) 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.

SDM Operation

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.

Data Logger Connection

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.
