SIRAX SV 824
The isolating switch amplifier SIRAX SV 824 is available in two-channel version and is used for transferring binary signals from fail-safe circuits to non-fail-safe circuits. The amplifier input may be either a sensor conforming to DIN 19 234 or a mechanical contact. Input and output signals are electrically insulated. Output signals available are relay contacts. Yellow LED's on the front of the unit signal energised output relays. The direction of action 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 instrument fulfils all the important requirements and regulations concerning electromagnetic compatibility EMC and Safety (IEC 1010 resp. EN 61 010). It was developed and is manufactured and tested in strict accordance with the quality assurance stand-ard ISO 9001. Production QA is also certified according to guideline 94/9/EG.
