SDM-SIO2R Digital Input Peripherals Campbell Scientific

 

 

Digital input peripherals are often used to extend data communications networks or to perform media conversions.

Overview

The SDM-SIO2R is a digital sensor expansion module that expands the serial I/O interface via Synchronous Device for Measurement (SDM) communications on a data logger. The serial I/O functionality is identical to the SDM-SIO1A One-Channel Serial I/O Module and the SDM-SIO4A Four-Channel Serial I/O Module, except it has two channels. The SDM-SIO2R also has terminals to connect sensor power and sensor heater power, which are controllable via the SDMGeneric instruction in CRBasic. 

Benefits and Features

  • Hot swappable in the field
  • Modular design
  • Expandable as needed
  • Removable terminals
  • Power control ability for each individual sensor
