Description
The X-AO 16 01 analog output module is intended for use in the programmable electronic
system (PES) HIMax.
The module can be inserted in any of the base plate slots with the exception of the slots
reserved for system bus modules. For more information, refer to the System Manual
(HI 801 001 E).
The module is equipped with 16 analog outputs with a nominal range of 4...20 mA.
i
If two modules are redundantly connected, only 8 odd outputs are available,
see Chapter 3.4.
The analog outputs are suitable for connecting ohmic, inductive and capacitive loads and
lamps in accordance with EN 61131-2.
The module has been certified by the TÜV for safety-related applications up to SIL 3
(IEC 61508, IEC 61511 and IEC 62061), Cat. 4 (EN 954-1) and PL e (EN ISO 13849-1).
Refer to the HIMax Safety Manual for more information on the standards used to test and
certify the modules and the HIMax system.
3.1
Safety Function
The module ensures its safety function using one extra safety switch for each channel pair
that is opened if a failure occurs.
The safety function is performed in accordance with SIL 3.
3.1.1
Reaction in the Event of a Fault
If the safety-related processor system of the module detects a module fault during
operation, the module adopts the safe state after a maximum of 16 ms and all the outputs
are de-energized in accordance with the 'de-energize to trip principle'. If a channel fault
occurs, both channels of the affected channel group are switched off.
The module activates the
Error
LED on the front plate.
3.2
Scope of Delivery
The module must be installed on a suitable connector board to be able to operate. If a FTA
is used, a system cable is required to connect the connector board to the FTA. Connector
boards, system cables and FTAs are not included within the scope of delivery.
The connector boards are described in Chapter 3.6, the system cables are described in
Chapter 3.7. The FTAs are described in own manuals.
