contacts 13-14 fulfil in consideration with a
B10d-value view the following requirements
(refer also to “Information within the meaning

Special terms for use in zone 2
Installation in Zone 2
The units are to be installed in switching or junction boxes, which•
consider the terms of EN 60079-15:2005.
The unit may only be installed and operated by personnel who are•
familiar with both these instructions and the current regulations for
safety at work and accident prevention.
The intrinsically safe circuits of the unit (light blue terminals) may•
be layed in explosion-endangered areas. In this procedure there is
to pay attention to a safe disconnection to all not intrinsically safe
circuits.
Attention:
Connecting and disconnecting of contacts of not intrinsically safe•
circuits under potentially explosion atmosphere is not allowed.
The housing may only be cleaned with a wet cloth.•
The life cycle of the module, relating to the type of protection “nC“, is•
at least 15 years. After end of this time the module is to be changed
or to be send to the manufacturer for a check-up!
Attention:
The temperature declarations (–25°C ≤ Ta ≤ +60 °C) of the module•
refer to a minimum volume of the switching box of approx. 2,400 cm3
per SRB. Make sure you maintain a distance of approx. 5 cm to other
sub-assemblies.

Function description
The SRB 200EXi-1R is a dual-channel safety relay module for the monitoring of emergency stop control devices, guard monitoring and safety•
magnet switches.
In the case of closed protection circuits S11-S12 and S21-S22 and closed feedback loop X1-X2 the module starts up after activating and releas-•
ing and close the enabling paths 13-14/23-24.
By actuation of the emergency stop control device or an other protection device the enabling paths 13-14/23-24 will be opened directly.•
The module can be restarted when both internal relays K1 and K2 have been dropped out.•
