Product Overview

The 7MH7152‑2BA02‑2AA‑Z C11 is a field‑mount BW500 belt‑scale integrator from Siemens Milltronics portfolio, designed for conveyor belt‑scale and loss‑in‑weight weigh‑feeder systems. It receives weight‑signal from load‑cells and pulse‑speed‑signal from conveyor speed‑sensor, calculates real‑time material flow‑rate and cumulative total‑weight.

Built‑in auxiliary I/O board delivers 2 analog‑inputs and 2 analog‑outputs to support PID‑control loop and online calibration function. Local LCD‑keypad supports on‑site commissioning, process‑value monitoring and fault‑diagnosis. SmartLinx expansion slot accepts PROFIBUS‑DP communication module to upload weighing‑data, total‑value and alarm status to plant DCS / PLC systems. Robust IP65 polycarbonate housing adapts to dusty outdoor and workshop‑field environments. Z‑C11 is special project‑specific suffix variant. OEM production is discontinued; available units are new‑old‑stock or refurbished spare‑parts for mining‑plant, cement‑plant bulk‑material‑handling‑system maintenance and retrofit projects西门子官方….

Application Notes

‑ Designed for field wall‑mount installation; keep cable‑gland seals intact to guarantee IP65 protection rating. ‑ Match load‑cell excitation and wiring parameters during commissioning; connect compatible speed‑sensor for accurate flow‑calculation. ‑ Auxiliary analog‑I/O board is fitted for PID‑control; confirm function requirement before deployment. ‑ PROFIBUS‑DP communication module is sold separately, not included in base unit. ‑ Not hot‑swappable; isolate AC power supply before wiring and unit replacement. ‑ Typical deployment: cement‑plant, mining‑site, power‑plant coal‑feeding, bulk‑material‑processing conveyor‑belt‑scale spare‑part stocking and site‑retrofit.
