Overview

SDM-CD16AC 16-Channel AC DC Relay Controller Module

With an SDM-CD16AC, 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.

Key Advantages

Greatly Expands Control Capacity
Use multiple modules for up to 256 control ports

Technical Description

The SDM-CD16AC 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-CD16AC is a synchronously addressed data logger peripheral. Data logger control ports 1, 2, and 3 are used to address the SDM-CD16AC, then clock out the desired state of each of the 16 control ports. Up to 16 SDM-CD16ACs 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 16 SDM-CD16ACs, allowing up to 256 ports to be controlled by one data logger
Includes LEDs that indicate when a port is active
Provides a manual override for each port
