SMD1102 / 1103 / 1113
INTRODUCTION
The SMD1102, SMD1103 and SMD1113 each contain a automaticallymonitoroneormoreanaloginputchannels.
10-Bit data acquisition system (DAS) with dedicated EE- If any input signal moves beyond its user-programmed
PROM alarm limit storage. The three devices communi- limitsthehostisnotifiedbytheSMBALERT#output,enabling
