This station has all the friendly features of a monitoring station. The Isolated Universal Analogue Inputs are software programmable using the user friendly MicroScan SCADA (Version 5.1 or later), or Station Programmer software. Each input can be configured for any of the following inputs:
RTD Pt100/Pt1000, Thermocouple, mA, mV, V & Pulse/Digital. There is a convenient wide choice of spans plus Custom spans can be configured also. The accuracy does not alter when changing spans.
The analogue inputs on the 2400-A16 can be expanded up to 76 using the 2100-M Input Multiplexers.
