Product DescriptionBus-powered safety input
module approved accordingto IEC/EN 61508 and EN954cat 4 by TÜV. The modulehas a single input for poten-tial-free contacts, and it usestwo Dupline® channels forsending the safety signal.The small dimension IP67housing makes itsuitable for de-central instal-
lation, e.g. inside a pull-cord
switch. The module is alwaysused in conjunction with theDuplineSafe Safety Relay GS38300143230. The “safestate” signal is transmittedcontinuously to the SafetyRelay as long as the inputcontacts are closed and themodule self-check is OK.

GS 7510 2101
Mode of OperationThe DuplineSafe SafetyInput module GS75102101
is used to monitor the statusof one potential-free contactin a safety device, e.g. anemergency stop palm buttonor pull cord switch. The sta-tus of the safety contact iscontinuously transmitted onthe Dupline® bus using adynamic signaling principleon two Dupline® channels.The Safety Input module isalways used in conjunctionwith the DuplineSafe SafetyRelay GS38300143230,which can monitor up to 63
Safety Input modules allconnected to the sameDupline® bus. If one or more
GS75102101’s fails to sendthe “safe state” signal the
Safety Relay will release.
Addressing
For addressing ofGS75102101, the Dupline-Safe Configuration UnitGS73800080 is used. TheGS75102101 must have 3Dupline® channels assignedto it
• Synchronization channel(same for all safetytransmitters)
• Safety Transmit channel 1
• Safety Transmit channel 2
Please refer to the usermanual for the DuplineSafe
Configuration UnitGS73800080 for detailedinstructions on how toconfigure the SafetyTransmitter GS75102101with the desired addresses.
The synchronization channelis used by the Safety Relayto send out a synchroniza-tion signal to the SafetyInput modules on the bus.Therefore, all the SafetyInput modules and the Safe-
ty Relay must be coded forthe same synchronizationchannel.
Safety Transmit channel 1and Safety transmit channel
2 are used by theGS75102101 to transmit thestatus of the safety switch ina dynamic way, ensuringredundancy, diversity andcontinuous updating. EachGS75102101 must be codedfor a unique channel pair notused by any otherGS75102101.
Please refer to the datasheetfor the safety relayGS38300143230 for detailedinstructions how to ensurecorrect addressing, installa-tion and configuration of aDuplineSafe safety system.
Installation RulesDue to fact that the Dupline-Safe input module is a singlechannel device (one input),there are specific installationrules that have to befollowed in order to achievean installation complyingwith EN954-1 Cat 4 andEN61508-SIL3:
- A short circuit betweenthe 2 wires in the cablebetween the terminals of theinput modules and the E-
stop button must be exclud-ed. This is possible, whenthe conditions, which arementioned in EN ISO 13849-2 table D.4 (see below), aremet.
- Short circuits between theadjacent terminals at theinput of the input moduleand between the terminals atthe E-Stop push-buttonmust be excluded. This ispossible, when the condi-
tions mentioned in EN ISO13849-2 table D.6 (seebelow) are met.
- The E-Stop button mustmeet the requirements fordirect opening according to
EN 60947-5-1 Annex K. Inthis case it is ensured, thatthe contact in the E-Stopbutton opens, when thepush-button is pressed (seetable D.8 in EN ISO 13849-2below).
These 3 conditions are usu-ally fulfilled, if the input mod-ule is placed very close tothe E-Stop push-button andin a closed housing, whichmeets IP 54 rating or higher.The push-button and thecabling must not bestressed by externalmechanical influences. TheE-Stop push-button musthave been approved accord-ing to EN 60947-5-1 fordirect opening.
Table D.4 – Conductors/cablesFault considered Fault exlusion Remarks
Short-circuit between any twoconductors
Short-circuit between conductors wich are
- Permanently connected (fixed) and protected
against external damage, e.g. by cable ducting,armouring, or
- seperate multicore cables, or
- within an electrical enclosure (se remark 1)), or
- individually shielded with earth connection.
1) Provided both the conductorsand enclosed meet the appropri-
ate requirements (see EN 60204-1(IEC 60204-1))
Short-circuit of any conductor toan exposed conductive part or toearth or to the protective bondingconductor.
Short-circuits between conductors which are withinan electrical enclosure (see remark 1).

Short-circuit between adja-cent terminals
Short-circuit between adjacent terminalsin accordance with remarks 1) or 2).
1)The terminals used are in accordance with aCENELEC or IEC standard and the requirement ofEN 60204-1:1997 (IEC 60204-1:1997), 14.1.1 aresatified.
2)The design by itself ensures that short-circuit isavoiding, e.g. by shapping shrink down plastic tub-ing over connection point.
Open-circuit of individualterminals
None -
