The series XM420 DW for EXTREME environmental requirements
The use of instrumentation in areas with highly fluctuating or extreme temperatures, high (air) humidity or at a higher vibration and shock loads or equipment creating heavy vibration or shocks is not uncommon. For these applications which require use under difficult to extreme conditions Bender has designed the measuring and monitoring relays series XM420 DW and guarantees precise measuring results under such conditions.
The relays are very resilient and are suitable to be used for the most diverse applications in extreme conditions and work even under the most difficult environmental conditions. They are resistant against humidity, shock and vibration according to DIN EN 50155 and can be operated in a temperature range from -40 to + 70° C (for a short time up to + 85° C for 10 minutes). Standardised tests according to DIN EN 60068-2-6 and DIN EN 60068-2-27 confirm a vibration resistance of 4 g and a shock resistance of 30 g. At the same time, the devices offer additional protection from interference pulses. Due to any increased resistance to EMC interference and a lower EMC emission a smooth operation of production systems and anything similar is ensured.
The measuring and monitoring relays of this series XM420-DW are equipped as standard with two alarm relays each supplied with a changeover contact. To ensure a simple conveyance or transfer of measured values to the measurement, control and regulation systems the devices are additionally equipped with standardised analogue interfaces (4 - 20 mA, 0 - 10 V). Furthermore, there is no falsification of measured values due to galvanic separation.
The device series have the following approvals: CE, UL and Lloyd‘s Register
Ideal for demanding applications such as:
- high shock loads
- high vibration loads
- extreme humidity/ice formation
- heavy contamination
- heavy temperature fluctuations
- wide temperature range.
