Emerson Rosemount 56-02-20-36-HT Analytical 56 Dual Input Analyzer pH Meters

56-02-20-36-HT: 24VDC power supply with 4 alarm relays, measurement 1 is contact conductivity, measurement 2 is ozone, and HART digital communication is used.

Rosemount 56-02-20-36-HT is a 1056 series intelligent four-wire dual-input transmitter. The following are its technical parameters:

Measurement parameters: It can measure a variety of parameters such as pH, ORP, ISE, resistivity, conductivity, percentage concentration, chlorine, oxygen, ozone, temperature, turbidity, flow and 4-20mA current input. The specific measurement combination of this model needs to be determined according to the configuration.

Power supply: 24VDC or 115/230AC (automatic switching).

Communication method: HART digital communication is a standard function, and Profibus DP communication option can also be selected to facilitate connection with PLC and DCS.

Other general features:

Display: High-resolution full-color screen (480x272 pixels) for easy viewing of process measurement values. The screen is similar to a computer, which is convenient for finding local configuration and daily calibration. It can also display measurement values, configure alarms and perform maintenance through a graphical local operation interface.

Diagnostic functions: Continuous monitoring of analyzer and sensor loops for fault and warning conditions, with data logger and event logger, the data logger records data from two channels every 30 seconds for 30 days as well as temperature, and the event logger audit trail records up to 300 important events.

Control functions: PID control with proportional, integral and derivative settings and up to 4 analog current outputs for continuous adjustment of the control device, and time proportional control with interval timer and 4 special application timers such as drain and injection, day and interval timers, delay timer and flow totalizer.

Secure access: Dual password access ensures secure operation and configuration of the device.

Data transfer: All process data and events of the unit can be transferred via the USB 2.0 data port for evaluation on a computer or wirelessly via the wireless THUM adapter (where supported).
