Description and application

CONVERTOR KST and KSTD CAN
CONVERTOR TEMPERATURE - CAN protocol

KST and KSTD CAN convertors temperature - CAN protocole are intended for converting the signal of Pt 1000/3850 resistance-type temperature sensing elements to the digital signal CAN / CANopen - CiA DS 301. These converters can be utilised in any control system compatible with CAN protocole digital output. Standard measuring ranges of the converter is -50 to 250 °C. Operating temperature range is -40 °C to 80 °C. These limits must not be exceeded even for a short time.

The convertors are designed to be operated in a chemically non-aggressive environment.

Two variants exist regarding to the design of the converter case:

1. KST CAN convertor: the plastic case is made of LEXAN material meets requirements of EN 45545-2, and is identical to, for example, the connection head of KS 120 sensors. It is provided with a wall bracket or with a clip for attaching to a DIN rail. The plastic box meets the IP 65 ingress protection requirements according to the EN 60 529 standard.

2. KSTD CAN convertor: the plastic box is made of LEXAN material meets requirements of EN 45545-2. It is intended for installation directly to a switchboard on a DIN rail.

TESTS, DECLARATION, CALIBRATIONS

The type tests are carried out by a notified body according to EN 50155 standard, as amended, Railway applications – Electronic equipment used on rolling stock, Art. 12.2.9, 12.2.11 - Electromagnetic Compatibility in accordance with EN 50121-3-2, as amended

- Insulation test in accordance with EN 50155, as amended

- Shock and vibration tests in accordance with EN 61373, as amended

The material of the plastic box and PCB meets a set of requirements for the R 24 materials according to the Table 5 for the fire hazard level HL1-HL2-HL3 of the EN 45545-2 standard, as amended. Can be supplied with materials complying with fire safety standard NFPA 130, as amended.

  • Manufacturer provides EU Declaration of Conformity.
  • Calibration – The final metrological inspection – comparison with standards or working instruments – is carried out for all the products. Continuity of the standards and working measuring instruments is ensured within the meaning of the Section 5 of Act no.505/1990 on metrology. The manufacturer offers a possibility to supply the sensors calibrated in SENSIT s.r.o.’s laboratory (according to requirements of the EN ISO/IEC 17025 standard, as amended) or in an Accredited laboratory.
