Operating range
1.1 For order code for "Output", option A "4-20 mA HART"/option B "4-20 mA HART, pulse/
frequency/switch output" with Ex i and option C "4-20 mA HART, 4-20 mA"
1.2 For order code for "Output", option A "4-20 mA HART"/option B "4-20 mA HART, pulse/
frequency/switch output" with non-Ex and Ex d
Sample calculation
Supply voltage of the supply unit:
– U
S
= 19 V
– U
term. min
= 12 V (measuring device) + 1 V (local operation without lighting) = 13 V
Maximum load: R
B
≤ (19 V - 13 V) :0.022 A = 273 Ω
The minimum terminal voltage (U
term. min
) increases if local operation is used

Preparing the measuring device
1. Remove dummy plug if present.
2.
NOTICE!
Insufficient sealing of the housing! Operational reliability of the
measuring device could be compromised. Use suitable cable glands corresponding
to the degree of protection.
If measuring device is delivered without cable glands:
Provide suitable cable gland for corresponding connecting cable (→ 24).
3. If measuring device is delivered with cable glands:
