Power:
Code -01: 98 to 132 Vac, 50/60 Hz, 8 watts max.
196 to 264 Vac, 50/60 Hz, 8 watts max.
Code -02: 20 to 30 Vdc, 8 watts maximum
Equipment protected throughout by double insula-
tion.
RFI/EMI: EN-50081-2
EN-50082-2
LVD: EN-61010-1
Input: Choice of single or dual sensor input with
measurement choices of pH/ORP and
dissolved oxygen. Field-commissioned
units allow user to change measurements
on either or both inputs. See combination
guide for valid combinations. For contacting con-
ductivity measurements, temperature element
must be a Pt 1000 RTD. For other measurements,
use either a Pt100 RTD, Pt1000 RTD, or 22k NTC
(D.O. only).
Outputs: Two 4-20 mA or 0-20 mA isolated outputs.
Continuously adjustable. Linear or logarithmic.
Maximum load 600 ohms. Output dampening with
time constant of 5 sec is user-selectable.
Alarms: Three alarm relays for process measure-
ment(s) or temperature. Alarm 3 can be
configured as a fault alarm, instead of a
process alarm. Each relay can be configured
independently. Alarm logic (high or low
activation) and deadband are
user-programmable.
Relays: Form C, single pole double throw, epoxy sealed
