Description
Product Overview
ABB 3BDH000741R1 CTI21-P Ex belongs to the Symphony Plus DCS system, and it functions as an intrinsically safe temperature input module. First of all, this card connects directly with RTD and thermocouple temperature sensors located in hazardous zones. It converts weak temperature signals into digital data that the DCS controller can process. Moreover, it carries ATEX and IECEx explosion-proof certification, so it isolates the safe control side and the explosive field side. It delivers reliable temperature measurement for process loops in oil, gas and chemical plants.
