SDM-IO16A 16-Channel Input/Output Module Campbell Scientific

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.

Overview

The SDM-IO16A has 16 ports that expand the digital input and/or output capability of Campbell Scientific data loggers. This module offers similar functionality to the control ports of the majority of Campbell Scientific data loggers.

Benefits and Features

• 16 digital I/O ports
• When configured as an input, each port can monitor logic state, count pulses, measure signal frequency, and determine duty cycle
• Consumes less than 1 mA power in most applications
• Compact package with spring-loaded, vibration-resistant terminals
• Connects to the data logger via three ports that can be shared with up to 15 other SDM devices
• Multiple different functions for programming each input and different function assignments for different ports on the same module
• Capability of each terminal to directly drive low-voltage valves or relays
• I/O lines protected against high-level surges with gas discharge tubes
