Product Description
The X-DO 12 01 relay module is intended for use in the programmable electronic system (PES)
HIMax.
The module can be inserted into any of the base plate slots with the exception of the slots
reserved for system bus modules. For more information, see System Manual (HI 801 001 E).
The module is equipped with 12 potential-free relay outputs with forcibly guided contacts. The
relay outputs are suitable for connecting ohmic and inductive loads.
The module has been certified by the TÜV for safety-related applications up to SIL 3
(IEC 61508, IEC 61511 and IEC 62061) as well as Cat. 4 and PL e (EN ISO 13849-1).
Refer to the HIMax Safety Manual (HI 801 003 E) for more information on the standards used to
test and certify the module and the HIMax system.
3.1
Safety Function
The module performs its safety function using two safety relays that are connected in series and
continuously monitored by the safety-related processor submodule.
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 and all the outputs are de-energized in accordance with the 'de-
energize to trip principle'. If a channel fault occurs, only the affected channel is 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 Field
Termination Assembly (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.
