SSR Series Modules
This chapter describes the SSR Series modules you can use with the
SC-2311.
Overview
SSR Series modules optically isolate field signals from the E Series DAQ
device, preventing computer damage caused by overvoltage transients in
your field wiring.
Note
All SSR Series modules use negative logic.
The SSR Series modules include the following:
•
Input modules
–
SSR-IAC-5, 120 VAC
–
SSR-IAC-5A, 240 VAC
–
SSR-IDC-5, 3 to 32 VDC
•
Output modules
–
SSR-OAC-5, 120 VAC
–
SSR-OAC-5A, 240 VAC
–
SSR-ODC-5, 3 to 60 VDC
See Appendix C,
Power Requirements for the SC-2311 with 5B and SSR
Series Modules
, to find the power requirements for your SSR Series
modules.
Input Modules
Input SSR Series modules sense voltages from a field source and return a
logic value to the E Series DAQ device. If a voltage within the selected
input range for the input module is present, it returns a logic low signal to
the DAQ device, otherwise it returns a logic high signal.
