The SREC is a safety relay expansion module
which can be used in conjunction with any IMO
SR relay
■ Three safety contacts
■ Operating voltage 24VDC, 115 and 230VAC
■ Any number of SRECs can be added
■ Force guided contacts
■ Self monitoring with redundancy
■ Emergency stop
■ Safety category 3 and stop category 0
■ Conforms to EN60204-1, VDE113-1, EN954-1

Description
Up to 3 additional safety contact paths per device can be created
with the expansion module SREC in combination with any IMO
SR series relay. Therefore any existing system can thus be
modularly expanded. Triggering is via the safety contact in the
mother device. The SREC also provides message contacts for
fault monitoring. The devices can be used in circuits up to safety
category 3 according to EN954-1:1996.
The SREC expansion unit is connected to the mother device via
four lines: the basic device (e.g., SR2C or SR3C) actuates the
SREC relay, two lines are required for feedback/fault monitoring.
Earth faults in the control lines are detected as well as any
internal faults. A multitude of SRECs can be connected to a
basic device so the safety contacts can be adapted to your
individual needs. For example, personal safety can be
guaranteed by simply adding a SREC when controlling a system
with components that can represent an additional risk.
The SREC has been designed so it fulfils the requirements
EN60204-1 for emergency stop devices stop category 0 and type
3 safety-category of EN954-1 when used in association with an
IMO safety relay.

These parts came to us as part of a lot of surplus stock from a large Milspec type Co. and have been kept in storage for some time, we have therefore classified them as ‘new other’. They are however in pristine condition still in their original packaging and ‘as new’ in all respects, the photographs are representative of their excellent condition, and, as with all our products they come with a full guarantee.
