ELM3544-0000 | 4-channel measuring bridge analysis, full/half/quarter bridge, 24 bit, 1 ksps

The ELM3542 and ELM3544 EtherCAT Terminals from the ELM3x4x economy series are designed for the evaluation of measuring bridges in full bridge, half bridge and quarter bridge configuration. With a maximum data rate of 1 ksps per channel they are ideally suited for the recording of less dynamic procedures, such as slow oscillations and corresponding weighing procedures. In return, they measure with extremely low noise and are temperature-stable up to an ambient temperature of 60 °C. The integrated bridge supply can supply 1 to 12 V and, like all other parameters, is adjustable online in the CoE at runtime. In addition, the ELM3542 features a connection for one TEDS-IC in the sensor per channel – this way the SG can be electronically read, detected and also written immediately upon plugging in. Apart from that, the ELM354x have all the features familiar from the fast ELM350x basic series, such as internally switchable extension resistors and comprehensive sensor and function diagnostics for industrial 24/7 operation. The 6-pin connector (push-in) is removable for maintenance purposes without releasing the individual wires.

Available on request as variant with factory calibration certificate or ISO 17025-/DAkkS-compliant certificate including Beckhoff recalibration service.
