HIMA HIMax®Relay Module X-D0 12 51

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.

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.

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.

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.

Structure

The module is equipped with 12 relay outputs; each of these outputs can be energized by a

relay.

All 12 relay outputs are electrically safely isolated from one another. Each relay output is safely

isolated from the voltage supply of the module by its own contact circuit. For safe insulation, the

air and creeping distances are designed in accordance with IEC 61131-2 for overvoltage class II

up to 300 V.
