This document applies to the following products:
•Product code: ReLy MULT1
•“Operating instructions” type label entry: 8024300
Document identification
Document part number:
•This document: 8024307
•Available language versions of this document: 8024300
You can find the current version of all documents at www.sick.com.
1.3 Target groups and structure of these operating instructions
These operating instructions are intended for the following target groups: project devel‐
opers (planners, developers, designers), installers, electricians, safety experts (such as
CE authorized representatives, compliance officers, people who test and approve the
application), operators, and maintenance personnel.
These operating instructions are organized by the life phases of the device: project
planning, mounting, electrical installation, commissioning, operation and maintenance.
The table below shows the target groups and how – for many applications – these are
typically divided up between the manufacturer and the entity operating the machine in
which the device is to be integrated:

and warning instructions in all chapters of the operating instructions!
In other applications, the operating organization is also the manufacturer of the equip‐
ment with the corresponding allocation of the target groups.

2 Safety information
2.1 General safety notes
DANGER
If the safety component is integrated incorrectly, the dangerous state may be ended to
late.
bPlan the integration of the safety component in accordance with the machine
requirements, see "Project planning", page 12.
DANGER
Hazard due to lack of effectiveness of the protective device
In the case of non-compliance, it is possible that the dangerous state of the machine
may not be stopped or not stopped in a timely manner.
bPlease read this document carefully and make sure that you understand the
content fully before working with the device.
bFollow all safety notes in this document.
Improper installation or manipulation can lead to serious injuries.
2.2 Intended use
The safety relay is an evaluation unit device for switching safety-related circuits on and
off for the following sensor types:
•Electro-mechanical switch/safety switch (EMSS)
•Safety sensors with monitored semiconductor output (OSSD)
•Safety sensors with test input (SCSD)
•Safety pressure mats (SMAT)
•Antivalent mechanical safety switch (CMSS)
The safety relay complies with class A, group 1 as per EN 55011. Group 1 encom‐
passes all ISM devices in which intentionally generated and/or used conductor-bound
RF energy that is required for the inner function of the device itself occurs.
The safety relay must only be used within the limits of the prescribed and specified
technical data and operating conditions at all times.
Incorrect use, improper modification or manipulation of the safety relay will invalidate
any warranty from SICK; in addition, any responsibility and liability of SICK for damage
and secondary damage caused by this is excluded.
UL/CSA applications
If the product is being used in accordance with UL 508 or CSA C22.2 No. 14, the
following conditions must also be met:
•To protect the device’s 24-volt voltage supply, use a fuse with a maximum voltage
of 4 A and a minimum of 30 V DC in accordance with UL 248.
NOTE
The safety functions have not be evaluated by UL. Authorization is in accordance with
UL 508, general applications.
2.3 Improper use
The safety relay is not suitable for the following applications (this list is not exhaustive):

8024307/2021-07-30 | SICK O P E R A T I N G I N S T R U C T I O N S | ReLy MULT1 7
Subject to change without notice
•At altitudes of over 4,000 m above sea level
•In explosion-hazardous areas
2.4 Requirements for the qualification of personnel
The protective device must be planned in, installed, connected, commissioned, and
serviced by qualified safety personnel only.
Project planning
For project planning, a person is considered qualified when he/she has expertise and
experience in the selection and use of protective devices on machines and is familiar
with the relevant technical rules and work safety regulations.
Mechanical mounting, electrical installation, and commissioning
For the task, a person is considered qualified when he/she has the expertise and
experience in the relevant field and is sufficiently familiar with the application of the
protective device on the machine to be able to assess whether it is in an operationally
safe state.
Operation and maintenance
For operation and maintenance, a person is considered competent when he/she has
the expertise and experience in the relevant field and is sufficiently familiar with the
application of the protective device on the machine and has been instructed by the
machine operator in its operation.

3.2 Construction and function
The safety relay ReLy MULT1 is an electrical switching device with inputs and outputs.
The safety capable inputs of the safety relay are connected to safety sensors or safety
switches.
2 safety capable inputs control the internal relays, which are used to reliably switch the
enabling current paths.
The enabling current paths close only when the two safety capable inputs close within
3 s of one another.
Actuators with positively guided contacts are connected to the enabling current paths.
3.3 Product characteristics
3.3.1 Interfaces
Inputs
•2 safety capable inputs
•Input for reset pushbutton or external device monitoring
Outputs
•3 enabling current paths (safe)
•2 application diagnostic outputs (not safe)
•2 Test outputs (not safe)
