SDM-CD16S中文资料CAMPBELL数据手册PDF规格书

Benefits and Features

Allows the data loggerto 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

Technical Description

This relay driver provides 16 DC voltage outputs that can be switched on and off manually or under datalogger 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 datalogger 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 datalogger's 12V while switching a higher voltage.

With a voltage range of up to 48 Vdcand a maximum current output per channel of 2 A, the SDM-CD165S can drive up to 100 W of power on each channel.
