About the ER-8/16
Thank you for buying the National Instruments ER-8/16. The ER-8 consists of eight isolated
single-pole double-throw (SPDT) or form C relay channels. The ER-16 consists of 16 isolated
SPDT or form C relay channels. The ER-8/16 can serve as a controller or switcher in laboratory
testing, production testing, and industrial-process monitoring and control applications. The
ER-8/16 operates with full functionality with most National Instruments digital I/O products. It
also interfaces with the Lab and MIO boards using the SC-205X Series cable adapters. The
ER-8/16 has onboard screw terminals for easy wire attachment. You can also build a 32-channel
ER system by daisy-chaining two ER-16s.
Detailed ER-8/16 specifications are in Appendix A, Specifications.
