3 Product Description
X-DO 12 51 is a NonSIL relay module 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. The relay outputs are suitable for
connecting ohmic and inductive loads.
It can be operated with safety-related modules and other NonSIL modules within one base
plate. Safety-related and NonSIL modules may not be wired redundantly.
The module is interference-free, in particular, with respect to EMC, electrical safety,
communication to the X-SB and X-CPU modules, as well as the user program.
Module and connector boards are mechanically coded, see Chapter 3.6.1. Coding avoids
installation of improper modules.
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 does not perform any safety-related functions.
The parameters and status for this module must not be used for safety functions.
3.1.1 Reaction in the Event of a Fault
If a module fault occurs, all outputs are switched off.
If the system bus fails, the outputs are de-energized.
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 use, 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.
