HART options
1)
1) The second analogue output (available for V1, WM550 and GPE) has no HART option.
• Slave, address # 0:
4 ... 20 mA active
• Slave, address #1 - #15:
fixed current (user selectable)
•Master:
max. current (≤ 24 mA) selectable by user;
typically 6 HART instruments (each 4 mA) can be connected
2)
2) Start-up current of the HART instruments has to be taken into account
