  • FM and CSA – Class I Div 2 approved, UL approved for general purpose

The Model 1056 dual-input analyzer offers single or dual sensor input with an unrestricted choice of dual measurements thus reducing the cost per loop and saving panel space. This multi-parameter instrument offers a wide range of measurement choices, supporting most industrial, commercial, and municipal applications.

The modular design of the instrument allows signal input boards to be field replaced making configuration changes easy. Live process values are always displayed during programming and calibration routines. Standard features include isolated inputs, seven embedded local languages, two 4-20mA current outputs and removable connectors for power and current outputs. HART® and Profibus DP digital communications are available. Model 1056 HART® units communicate with the Model 375 HART® handheld communicator and HART® hosts, such as AMS Intelligent Device Manager. Model 1056 Profibus units are fully compatible with Profibus DP networks and Class 1 or Class 2 masters.
