LISTED

Pollution Degree 2: Normally only non-conductive pollution occurs. Occasionally, however, a temporary conductivity caused by condensation must be expected.

Altitude: for use up to 2000 meter (6562 ft.)

RFI/EMI: EN-61326

LVD: EN-61010-1

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 4-20 mA or 0-20 mA isolated current outputs. Fully scalable. Max Load: 550 Ohms. Output 1 superimposes the HART digital signal. Outputs can be programmed for PID control. Output dampening can be enabled with time constants from 0 to 999 seconds. HART digital communications transmitted via current 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 deadband are user-programmable.

*USP alarm can be programmed to activate when the conductivity is within a user-selectable percentage of the limit. conductivity/resistivity measurement only)

Relays: Form C, SPDT, epoxy sealed
