The device is offered in 24VDC or 115/230 auto-switching AC. HART digital communications is a standard feature.
The unit supports SMART pH sensors by Rosemount Analytical. All configurations meet UL approval requirements for Ordinary Locations.

Event Logger Audit Trail: Up to 300 significant events are recorded
PID Control: Proportional, Integral and Derivative settings allow up to four analog current outputs to adjust a control device that has continuous adjustability
Real-time Clock: Applies time/data stamps to all process data and events
USB Data Port: Allows local transfer of all process data and events for evaluation on a computer
Timer Functions: Time-proportional control, interval timers and four special application timers: bleed and feed, day and time interval timers, delay timer and a flow totalizer.
Security Access: Two levels of password access
Diagnostics: Continuously monitors and records the analyze and sensor(s) for fault conditions
Wireless-ready: HART versions enable wireless transmissions of process variables and diagnostics from hard-to-reach locations with the Wireless THUM Adaptor.

Altitude: for use up to 2000 meter (6562 ft.)
Pollution Degree 2: Normally only non-conductive pollution
occurs. Occasionally, however, a temporary conductivity caused by condensation must be expected.
Input: One or two isolated sensor inputs. Measurement choices
of pH/ORP, resistivity/conductivity/TDS, % concentration, ratio
conductivity, total and free chlorine, monochloramine, dissolved
oxygen, dissolved ozone, turbidity, pulse flow, temperature and
raw 4-20mA input. For contacting conductivity measurements,
temperature element must be a Pt1000 RTD. For other measurements (except ORP, flow and turbidity), use either a PT100 RTD, PT1000 RTD, or 22k NTC (D.O. only).
Outputs: Four actively powered 4-20 mA or 0-20 mA isolated current outputs. Fully scalable. Max Load: 550 Ohms. Outputs can be
programmed for PID control. Output dampening can be enabled
with time constants from 0 to 999 seconds. HART digital communications which is superimposed on output 1 is standard on all
units (option code –HT).
Alarms: Four alarm relays for process measurement(s) or
temperature. Any relay can be programmed for any measurement,
timer, TPC or fault alarm operation, instead of a process alarm. When selected, a fault alarm will activate the relay when a sensor or analyzer fault occurs. Each relay can be configured independently. Alarm logic (high or low activation or USP) and deadbands are user-programmable.
Relays: Form C, SPDT, epoxy sealed
Inductive load: 1/8 HP motor (max.), 115/240 VAC
Terminal Connections Rating
Power connector (-02 24VDC power supply and -03 85-264VAC
power supply): 24-12 AWG wire size.
