1. Application
The alarm unit SIRAX C402 (Figure 1) is normally applied
to monitor the limits of both current and voltage measure-
ments. 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.
Production QA is also certified according to guideline
94/9/EG.
3. 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:
Table 1: Instrument in standard (non-Ex) version
Standard input signals
0 ... 20 mA / 0 ... 10 V
4 ... 20 mA / 2 ... 10 V
± 20 mA / ± 10 V
Please complete the Order Code 402-6... .... .. according to Table 3 for versions with user-specific configuration.
Contact outputs A1 / A2

2. Features / Benefits
● Alarm units plugs onto backplane (mechanically latched by fasten-
ers), all electric connections made to the backplane and not to the
SIRAX C 402 / Thus no wiring when replacing devices
● With 2 alarm circuits
● 2 heavy current relay outputs with 1 changeover contact each
● Analogous trip point adjusted by 12-turn potentiometer, adjusted
trip point measurable on test sockets, 0...1 V
● Sense of relay action and associated LED's switchable by
jumpers
● Electrical insulation between measuring input, contact outputs
and power supply / Fulfils EN 61 010
● Non-standard user-specific ranges available
● AC/DC power supply / Universal
Available in type of protection "Intrinsic safety" [EEx ia] IIC
