INPUT SPECIFICATIONS

■ DC Current: 4 – 20 mA DC

Measurable range: 3.75 – 23 mA DC

Maximum input current

Non-approved: 100 mA

Explosion-proof: 23 mA

Intrinsically safe: Refer to ‘Safety Parameters.’

Voltage drop: Approx. 3.7 V with 4 mA

Approx. 4.0 V with 20 mA (Equivalent input impedance:

Approx. 200 Ω)

The minimum required supply voltage to the 2-wire

transmitter added with the indicator’s voltage drop at the

maximum input current must be within the output voltage

range of the 2-wire transmitter’s excitation supply.

INSTALLATION

Operating temperature: -40 to +85°C (-40 to +185°F)

(See Safety Parameters for use in a hazardous location.)

Weight:

· Unit

Approx. 1.3 kg (2.9 lb), aluminium

Approx. 4.0 kg (8.8 lb), stainless steel

Approx. 2.0 kg (4.4 lb), TIIS flameproof

· Mounting bracket set (option)

Approx. 0.78 kg (1.72 lb)

PERFORMANCE

Accuracy: ±0.01 mA

Temp. coefficient: ±0.015 %/°C (±0.008 %/°F) at 4 – 20 mA

input

Dielectric strength: 1500 V AC @ 1 minute

(input to outdoor enclosure)

HOW TO CALCULATE ACCURACY AGAINST SCALE

Example 1: 4 – 20 mA input, Scale 0 – 100

Accuracy = 0.01 mA ÷ (20 – 4)mA × 100 = 0.063 %

Display Error = (100 – 0) × 0.063 % = ±0.063 digits

Example 2: 10 – 20 mA input, Scale 100 – 1000

Accuracy = 0.01 mA ÷ (20 – 10)mA × 100 = 0.1 %

Display Error = (1000 – 100) × 0.1 % = ±0.9 digits
