4. Output Wiring:
Option G, H, K
Option L
Option M, N
Non-Ex Versions
5. Description:
This version of converter is similar to the existing Modis converter range but has no Ex
approvals.
It has been introduced to provide the options of Profibus PA, Foundation Fieldbus (planned)
and galvanically isolated outputs for non-Ex environments such as food and pharmaceutical
applications.
6. Available Versions:
L
2 x 4-20mA passive output (freely programmable). HART protocol on first output. Both
outputs galvanically separated from each other and the power supply.
M
1 x 4-20mA passive output (freely programmable) and 1 x Profibus PA passive output
(HART protocol not available). Both outputs galvanically separated from each other
and the power supply.
N
Like M, but 1x Fieldbus Foundation passive output (pending)
Supply Voltage:
These converters are available with the same two voltage options:
24V AC/DC
100 – 230 V AC
P- P+
or
S- S+
or
C- C+
