About Output and Control Peripherals

Output and control peripherals enable you to add channels to control other devices, such as activating external devices and increasing the number of digital output or digital input channels of a data logger. Some of these peripherals have built-in relays to control external devices, and other peripherals may require connected relays depending on what you want to control.

	Function	Number of Channels	Operating Temperature	Operating Voltage
SDM-CD8S Eight-Channel Solid-State DC Controller	Allows the data logger to control dc devices that have a moderate current load, such as solenoids, solenoid valves, dc motors, stepper motors, lights, horns, heaters, and fans.	8	-40° to +70°C	12 Vdc
SDM-CD16S 16-Channel Solid-State DC Controller	Allows the data logger to control dc devices that have a relatively high-powered load, such as solenoids, solenoid valves, dc motors, stepper motors, lights, horns, heaters, and fans.	16	-40° to +70°C	12 Vdc
SDM-AO4A 4-Channel Analog Output Module	Increases the number of continuous analog output (CAO) ports available to a data logger. CAOs are used for proportional control or driving strip charts.	4	-40° to +60°C	12 Vdc nominal (9.6 to 16 Vdc)
SW12V 12 V Power Switch Assembly	Enables a data logger to determine whether 12 Vdc power is passed onto an external device.	—	—	—
7321 SPST Single-Channel Solid-State Relay	Allows a data logger to control one or two dc devices.	1	-40° to +100°C	1 to 100 Vdc
