REQUIREMENTS
A:
Loop Power (+T)
B:
Channel 1 (CH1)
C:
Channel 2 (CH2)
2 HART-compatible channels,
which communicate via digital
signals only.
Mode:
Half-duplex.
Data Rate:
1200 BPS
asynchronous.
Parity:
Odd.
Format:
8 bit.
Modulation:
Phase coherent,
frequency shift keyed (FSK) per
Bell 202.
Carrier Frequencies:
Mark 1200
Hz, Space 2200 Hz, ± 0.1%.
Up to 6 HART Modules and 32
HART devices maximum.
Point-to-Point Mode:
2 HART
devices per Module (1 per channel).
Multi-drop Mode:
Up to 10 HART
devices per Module (5 per channel).
Total power supplied through
module for HART devices is 20 mA
per channel at 10 to 29 Vdc. Each
HART device typically uses 4 mA.
Loop Source:
11 to 30 Vdc, 40
mA maximum from ROC/FloBoss
power supply or ROC364 I/O
converter card.
Module:
4.9 to 5.1 Vdc, 17 mA
maximum.
