Strain Gage Input Modules

For the Allen-Bradley SLC-500 (1746), ControlLogix (1756), and MicroLogix/CompactLogix (1769) PLC

Model HM-604

Model HM-1520

Model HM-1756

Two separate channels of signal conditioning on each module eliminates the cost of adding amplifiers or analog input modules. Parameters can be set from processor memory locations for setting upper and lower control limits. The modules accept a variety of Helm strain gage force sensors and load cells.
