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-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. | — | — | — |
7321 |
Allows a data logger to control one or two dc devices. | 1 | -40° to +100°C | 1 to 100 Vdc |
