Inputs (intrinsically safe)

• Repeater power supply operation (feeding input for 2-conductor transmitter or 2-conductor measur-
ing transducer) on terminal 4.1 (+) and 4.2 (-)
• Input isolating amplifier operation (non-feeding input for four-wire transmitter/power sources) at ter-
minals 4.2 (+) and 4.3 (-)
