DESCRIPTION

The BASI Isolated Intelligent transmitter with universal input model BUSC7801 is an economical and excellent choice foraccurate signal conversion. BUSC7801 also features easy stocking and configuration.The transmitter is programmable with BASI TraCon software including Thermocouples J, K, T, R, S, B and RTD Pt-100, Pt-1000, PTC, mV, V and mA DC inputs. One scaleable 0(4) -20mA or 0-10 VDC outputs. Designed to fit in a standard 11-pole relay socket, mounting is very easy and maintenance a snap. The transmitter can be configured without external power.
