Ex n HART universal module, Zone 2
Series 9469/35

Function and Device Design
4.1
Function
Application range
The 9469/35 HART universal module is provided to connect up to 8 non-intrinsically safe
signals to the IS1+ Remote I/O system. Upon installation in a suitable enclosure,
the device can used in gas and dust hazardous areas of Zone 2 and Zone 22 or in safe
areas. The device must be used in areas with a degree of pollution of 2 or greater.
Parameterisation procedure
All 8 channels of the module are individually configurable as inputs or outputs and can
be used as analogue inputs for 2-conductor transmitters or as outputs for final control
elements or indicating devices. Channels 4, 5, 6 and 7 can either be used as analogue
or binary inputs/outputs. If configured as an analogue input, connecting 3-/4-conductor
transmitters (including power unit) is also possible.
If configured as a binary input, connecting a 3-conductor PNP proximity switches with a
24 V power supply is also possible (alternatively as a binary output for connecting
solenoid valves (24 V / 0.5 A)).
Power supply and monitoring procedure
Each analogue channel enables digital communication with the connected transmitters
via the HART protocol. The power supply for 3-conductor proximity switches and solenoid
valves comes from an external power supply via a separate X0 terminal. This also
contains the "Plant STOP" control input for safe shutoff of all channels. All inputs and
outputs are monitored for short circuiting and line breakage and are short-circuit proof.
DANGER
Explosion hazard due to improper use!
Non-compliance results in severe or fatal injuries.
• Use the device only in accordance with the operating conditions
described in these operating instructions.
• Use the device only for the intended purpose specified in these
operating instructions.
Function-compatible replacement for IS1 I/O modules: Series 9461/15 and
9466/15.
