Module 8 kênh đầu ra DC Campbell Scientific SDM-CD8S

Overview

The SDM-CD8S adds capability to a datalogger by controlling dc devices that have a moderate current load, such as solenoids, solenoid valves, dc motors, stepper motors, lights, horns, heaters, and fans. The SDM-CD8S is targeted for applications requiring only a few control ports and where a larger, high-powered relay module (such as the SDM-CD16S) is not necessary.

Benefits and Features

  • Allows the datalogger to control dc devices that have a moderate current load, such as solenoids, solenoid valves, dc motors, stepper motors, lights, horns, heaters, and fans

  • Provides a manual override

  • Enables multiple SDM-CD8S devices to be wired to one datalogger, increasing the number of devices that can be controlled

  • Includes LEDs that provide a visual indicator of active outputs

Detailed Description

The SDM-CD8S has eight dc-voltage outputs and returns that can be switched on and off manually or under datalogger control. When the manual control switch is in the ON position, outputs are controlled by the position of the individual rocker switches. In the OFF position the state of the relays is controlled by the SDM commands from the datalogger.

The voltage range for this device is 8 to 26 Vdc. It can deliver up to 1 A per channel with a maximum of 6 A total for all channels. The power Input (8 to 26 Vdc) powers both the outputs and the SDM-CD8S logic.

SDM Operation

The SDM-CD8S is a synchronously addressed datalogger peripheral. Datalogger control ports 1, 2, and 3 are used to address the SDM-CD8S, then clock out the desired state of each of the 8 control ports. Up to 15 SDM-CD8S Controllers may be addressed, making it possible to control a maximum of 120 ports from the first three datalogger control ports.
