1. Application
The alarm unit SINEAX C402 (Fig. 1) is normally applied to
monitor the limits of both current and voltage measurements.
The status of the device is signalled remotely by a relay and
locally by LED's. The electrical insulation between input,
output relay contacts and the power supply conforms to
IEC 1010. The value detected by the alarm unit is set on a
potentiometer and measured at test sockets on the front
of the unit.
The alarm unit 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 standard ISO 9001/EN 29 001.
Production QA is also certified according to guideline
94/9/EG.
3. Standard version
The following alarm unit in housing S17 is available as standard version. Measuring input set to 0 ... 20 mA resp. 0 ... 10 V
- acc. to external connection - (plug-in jumper J1 in position B2). Any of the standard ranges simply selected by positioning
plug-in jumpers J1. Quoting the order No. is sufficient when ordering:
