Enclosure

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).

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)

Compliance information

CE approved (with all sensor types). Listed for use in general locations to UL and

CSA safety standards by ETL (with all sensor types).

Certain AC mains powered models are listed for use in general safety locations to

UL and CSA safety standards by Underwriters Laboratories (with all sensor types).

Digital communication Optional Modbus, RS232/RS485, Profibus DPV1 or HART network connection for

data transmission

Data logging Secure Digital Card (32 GB maximum) or special RS232 cable connector for data

logging and performing software updates. The controller will keep approximately

20,000 data points per sensor.

Warranty 2 years
