I/O modules & signal converters for load cells
Seneca I/O modules for strain gauge load cells can be integrated into all weighing systems in a flexible form. In addition to weight, force, or tension gauges, "SG" modules allow data acquisition in stand-alone mode or interfaced with third-party systems. The devices provide multiple methods of calibration of the load cell connected directly by the web server, with or without dedicated software, with or without sample weight, and with or without the acquisition of factory parameters. The modules are available in Z (17.5 x 102.5 x 111 mm ) and R (53.3 x 90 x 32.2 mm ) form factors depending on installation requirements. Measurement, performed in 4- or 6-wire technique, is available via ModBUS RTU, ModBUS TCPIP, CANopen, Profinet IO communication protocols, and mA-V analog output. SG modules have primary characteristics of robustness, safety, and accuracy with three-way galvanic isolation up to 1,500 Vac. The accuracy class is 0.01% with load cell sensitivity from 1 to 64 mV/V. They can directly power the strain gauge. The range of SENECA strain gauge modules includes versions that support ModBUS RTU, ModBUS TCP-IP (Ethernet), CANopen, and soon Profinet IO protocols.
