Description
This Thermocouple Input module is applicable where only a single temperature (or voltage or current) is to be monitored. The I-7011PD has an integrated 4½ Digit LED Display to display values. The I-7011PD has a Digital Input channel to accept an input from a switch/relay or similar, along with 2 Digital Outputs which can be used for Alarm Output.
