4.1.3 The Six Basic Module Types in
Detail
NAMUR Pulse Isolator
The pulse isolator ACT20X-HDI-SDO is a special
signal isolator/converter for NAMUR sensor signals
from within Ex Zone 0. Transistor or relay outputs
are available on the output side. A dual-channel
version is optionally available.
Solenoid/Alarm Driver
The digital actuator driver (solenoid valve
switch/alarm signaling facility) ACT20X-SDI-HDO is
equipped with an input in the non-hazardous area
and an output in Ex Zone 0.
HART-Transparent Repeater
The ACT20X-HAI-SAO signal isolator is a HART-
protocol transparent signal isolator for analogue
input signals from hazardous area Zone 0 sources.
Its output side provides an analogue signal for safe
area devices. A dual-channel version is optionally
available.
HART-Transparent Driver
The proportional actuator driver ACT20X-SAI-HAO
is HART-protocol transparent. The input has been
designed for use in non-hazardous areas, the output
for Ex Zone 0. A dual-channel version is optionally
available.
Temperature/mA Converter
The ACT20X-HTI-SAO temperature signal
isolator/converter facilitates utilization of Pt100
sensors. The input circuit is designed for intrinsically
safe signals from within Zone 0. Analogue signals
are made available on the output side for safe area
devices. A dual-channel version is optionally
available.
Universal Converter
The universal isolator/converter ACT20X-HUI-SAO
is a user configurable temperature and signal
converter for Pt100, thermal and current (mA) inputs
from within Ex Zone 0 as well as an output for non-
hazardous area devices.
