Overview
The 8170+ 1/8 DIN single loop controller has 3-point stepping control designed specifically for open loop, valve motor drive (VMD) applications. It incorporates advanced tuning algorithms, with selectable pre-tune and self-tuning for easier setup. In addition to the VMD outputs, further output options exist which can be designated as outputs for alarms, 24 VDC transmitter power supply, retransmit process value or setpoint.
