Model 1057 Dual Input Intelligent Analyzer
Four-Wire

The Model 1057 analyzer offers three sensor inputs and four current outputs thus reducing the cost per loop and saving panel space. The modular design allows signal input boards to be field replaced making configuration changes easy. Conveniently, live process values are always displayed during programming and calibration routines. Standard features include electrically isolated inputs, seven menu languages, four 4-20mA current outputs, 4 alarm relays and removable connectors.

For applications requiring wide range conductivity measurements, use Rosemount Analytical’s Model 410VP PUR-SENSE 4-electrode sensor. It is not affected by fouling and is supported by the same contacting conductivity signal board as traditional 2-electrode sensors.

The Model 1057 accepts one, two or three inputs. Four 0/4-20 mA current outputs can be programmed to correspond to measurement or temperature.

The instrument fits standard ½ DIN panel cutouts. The versatile enclosure design supports panel-mount, pipe-mount, and surface/wall-mount installations.

Inputs are isolated from other signal sources and earth ground. This ensures clean signal inputs for single and dual input configurations. For multi-input configurations, isolation allows any combination of measurements and signal inputs without cross-talk or signal interference.
