3. Overview of the parts
Figure 2 shows those parts of the device of consequence for
mounting, electrical connections, configuration switch and
other operations described in the Operating Instructions.
4. Brief description
The isolating switch amplifier SINEAX SV 824 is used for
transferring binary signals.
The amplifier input may be either a sensor conforming to
DIN EN 50 227 or a contact. Input and output signals are
electrically insulated. The output is either an auxiliary relay
with a potentially-free changeover contact.

Green LED for signalling operating status
LED1,
LED2 Yellow LED’s for status display of relays A1 and A2
Red LED for open and short-circuit monitor (both inputs)
Yellow LED’s on the front of the unit signal energised output
relays. The relationship of the output can be configured with
the aid of switches which are also located on the front of the
unit.
Provision is made for monitoring the input with respect to
open and short-circuits. Should one of these faults occur, the
output relay of the channel concerned resets and the fault is
signalled by the red LED on the front of the unit. The
monitoring circuit is enabled by a switch (e.g. for use with
mechanical transmitter contacts).
The device fulfils the protection requirements of the EMC
guidelines (89/336/EWG). The device bears the CE symbol.
