Specification Details
Component description Microprocessor-controlled and menu-driven controller that operates the
sensor and displays measured values.
Operating temperature -20 to 60 ºC (-4 to 140 ºF); 95% relative humidity, non-condensing with
sensor load <7 W; -20 to 50 ºC (-4 to 104 ºF) with sensor load <28 W
Storage temperature -20 to 70 ºC (-4 to 158 ºF); 95% relative humidity, non-condensing
Enclosure
1
NEMA 4X/IP66 metal enclosure with a corrosion-resistant finish
Power requirements AC powered controller: 100-240 VAC ±10%, 50/60 Hz; Power 50 VA
with 7 W sensor/network module load, 100 VA with 28 W
sensor/network module load (optional Modbus, RS232/RS485, Profibus
DPV1 or HART network connection).
24 VDC powered controller: 24 VDC—15%, + 20%; Power 15 W with
7 W sensor/network module load, 40 W with 28 W sensor/network
module load (optional Modbus, RS232/RS485, Profibus DPV1 or HART
network connection).
Altitude requirements Standard 2000 m (6562 ft) ASL (Above Sea Level)

degree/Installation
category
Polution Degree 2; Installation Category II
Outputs Two analog (0-20 mA or 4-20 mA) outputs. Each analog output can be
assigned to represent a measured parameter such as pH, temperature,
flow or calculated values. Optional module supplies three additional
analog outputs (5 total).
Relays Four SPDT, user-configured contacts, rated 250 VAC, 5 Amp resistive
maximum for the AC powered controller and 24 VDC, 5A resistive
maximum for the DC powered controller. Relays are designed for
connection to AC Mains circuits (i.e., whenever the controller is operated
with 115 - 240 VAC power) or DC circuits (i.e., whenever the controller is
operated with 24 VDC power).
Dimensions ½ DIN—144 x 144 x 180.9 mm (5.7 x 5.7 x 7.12 in.)
Weight 1.7 kg (3.75 lb)
