GM9907 Packing & Bagging Controller

Single & dual scale packing control for automated bagging machines
The GM9907 is a dedicated packing and bagging controller for automated bagging machines. Available in single-scale (L2) and dual-head (LD) configurations, it manages the full packing cycle — feeding, weighing, discharge and bag handling — with high accuracy and repeatability. Industry-grade integration for food, feed, chemical, mining and bulk material packaging across South Africa.

VARIANTS

Single hopper or dual head — choose the right configuration

The GM9907 packing controller is available in two physical configurations. Both share the same I/O architecture, communication interfaces and core algorithms — they differ in scale capacity (one or two scales) and the bagging modes available.

Specification GM9907-L2 (single hopper) GM9907-LD (dual head)
Configuration Single-scale incremental method Dual-scale increment method
Bagging modes Net, Gross, Jumbo Bag, Servo motor, PLC Net, Gross, Bulk scale
Recipe storage 20 recipes 40 recipes
I/O 28 (12 in / 16 out) 28 (12 in / 16 out)
Communication RS-232, RS-485, MODBUS-RTU, USB RS-232, RS-485, MODBUS-RTU, USB
Display 7-inch resistive touch screen 7-inch resistive touch screen
Dimensions 190 × 124 × 48 mm 199 × 133 × 47 mm
Best fit Single bagging head, mainstream throughput Dual bagging head, higher throughput, AB separate & combined modes

How to choose

Choose the L2 for single-head bagging machines, smaller production lines, or where the five filling modes (including Jumbo Bag and PLC supervisor mode) are required.

Choose the LD for dual-head bagging machines, higher throughput, or where dual hopper AB-separate / AB-combined packing modes are needed.
