Hazardous area weigh module / electronic / digital / for silos

SIWAREX WP521 ST and WP522 ST are technology modules for the SIMATIC S7-1500 advanced controller family and are optimally prepared for gravimetric level measurement of silos and hoppers as well as for platform scales. Beside that the weighing modules can also be used for weighing applications in hazardous locations (with Ex-interface SIWAREX IS).
The new technology module is available in two variants: SIWAREX WP521 ST as single channel option for the set-up of one scale and SIWAREX WP522 ST as two-channel option for the set-up of two independent scales.
Integrated in SIMATIC S7-1500 all advantages of the automation system can be used. The free ?ready-for-use? application helps to create fast and easily customer and application specific solutions. Besides that, the service software SIWATOOL V7 enables a quick and user-friendly Different interfaces and connection possibilities are available on board:

SIMATIC S7-1500 system bus, Modbus TCP/IP (Ethernet), Modbus RTU (RS485), four digital outputs and three digital inputs. The integrated monitoring function of the load cells impedance as well as the process and diagnosis alarm functions optimize the plant security resp. plant availability
