I-7011PD Thermocouple I/P Module W/LED Display (1AI+1DI+2DO)

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.

Features

• LED value display
• 16 bit ADC
• 3000V dc inter module isolation
• Integrated digital input and output
• Event counters
• Integrated digital display option
• Autonomous alarm output
• Direct measurement of thermocouples voltage and current
• Cold Junction Compensation for thermocouples
• Can be Configured using simple ASCII Commands
