Power supply

1)
2-wire; 4-20mA HART
2)
"Approval" Terminal voltage U at the device
• Non-Ex 11.5 to 35 V
• Ex nA
• CSA GP
Ex ic 11.5 to 32 V
Ex ia / IS 11.5 to 30 V
• Ex d / XP 13.5 to 30 V
• Ex ic[ia]
• Ex tD / DIP
1) Feature 020 of the product structure: option A
2) Feature 010 of the product structure
3) For ambient temperatures T
mA). The startup current can be parametrized. If the device is operated with a fixed current I ≥ 4,5 mA (HART multidrop mode), a voltage of U ≥
11,5 V is sufficient throughout the entire range of ambient temperatures.
4) For ambient temperatures T
mA).
