140AII33000 Intrinsically Safe Analog Input Module
Overview
The Quantum 140AII33000 Intrinsically Safe Analog Input module will interface with
eight intrinsically safe analog inputs, which are software-configurable on a module
basis with either RTD/Resistance or thermocouple/millivolt inputs.
When it is configured as an RTD/Resistance Input module, it supports 100Ω, 200Ω,
500Ω, and 1000Ω platinum (American or European) and nickel sensors. The module
also allows any mix and match of sensor type or resistance inputs that can be
configured by the software.
When it is configured as a Thermocouple/Millivolt Input module, it accepts B, J, K,
E, R, S and T type thermocouples. The module also allows any mix and match of
thermocouple or millivolt inputs that can be configured by the software.
