Product Line

Function Number of Channels Operating Temperature Operating Voltage

SDM-CD8S

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

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-IO16A

Expands the digital input and/or output capability of a data logger. 16 -40° to +70°C 12 Vdc (nominal 9 to 18 V)

SDM-AO4A

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

Enables a data logger to determine whether 12 Vdc power is passed onto an external device.

A6REL-12

Controls up to 12 external ac or dc devices. 6 -40° to +70°C 12 Vdc nominal (8.4 to 24 Vdc)

A21REL-12

Allows a data logger to control up to four external ac or dc devices. 4 -25° to +50°C 12 Vdc
