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.

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.
