Electrical data for operation in zones 1, 21, 22
4.2.1
Devices with HART protocol
When operating in potentially explosive areas, observe the following electrical data for the transmitter
signal inputs and outputs. For the current output version (active/passive), see the identification marking
in the device's terminal box.
Model: 406012/1-1, 406013/1-1, 406015/1-1, 406016/1-1, 406018/2-1 (dual-compartment housing),
406019/2-1 (dual-compartment housing)

a
Intrinsically safe single-channel or multichannel barriers (supply isolators) with resistance characteris-
tic curve must be used.
b
For "active" current output.
c
For "passive" current output.
d
Only available in conjunction with passive current output.
All inputs and outputs are galvanically isolated from each other and from the voltage supply.
