Description
HART-Transparent Drivers, Type ACT20X-SAI-HAO-S, Type ACT20X-SAI-HAO-P and Type
ACT20X-2SAI-2HAO-S, Type ACT20X-2SAI-2HAO-P for rail mounting, are 24 V powered
isolating barriers that serve as current output isolators for 4 - 20 mA signals with HART
communication.
The HART-Transparent Driver:
Type ACT20X-SAI-HAO-S and Type ACT20X-SAI-HAO-P are one channel versions.
Type ACT20X-2SAI-2HAO-S and Type ACT20X-2SAI-2HAO-P are two channel versions.
The driver provides a potential free contact for status indication.
Ambient temperature range -20 °C to +60 °C.
Marking
The equipment marking may additionally include the code II 3 G Ex nA nC IIC T4 Gc.
Electrical data
Supply (terminals 51, 52): U = 19,2 ... 31,2 Vdc.
Status-Relay output (terminals 53, 54):
U ≤ 32 Vac or 32 Vdc, I ≤ 0,5 Aac or I ≤ 1 Adc respectively.
If the Driver is installed outside the hazardous area, the following data for the relay contacts apply:
U ≤ 110 Vdc or 125 Vac, I ≤ 0,3 Adc or I ≤ 0,5 Aac respectively.
Inputs (terminals 41, 42 resp. 43, 44): I = 4 ... 20 mA.
For all circuits above: U
m
= 253 Vac (max. frequency 400 Hz).
Loop supply outputs (terminals 11, 12 resp. terminals 21, 22):
in type of protection intrinsic safety Ex ia IIC/IIB/IIA/IIIC/I, with following maximum values:
U

= 0,65 W;

o
= 0,08 µF (IIC) or 0,65 µF (IIB) or 2,15 µF (IIA) ) or 3,76 µF (I);
L

For group IIIC, the parameters of group IIB apply.
Both channels (terminals 11...14 and terminals 21...24) are infallibly galvanically isolated from
each other and from the non-intrinsically safe supply and output circuits.
