Product Details
The HI 1746-WS Weigh Scale Module is a self-contained
microprocessor-based I/O module with control inputs and outputs.
The HI 1746-WS is designed to be easily plugged into the back plane
of an AB SLC 5/02, 5/03, 5/04 or 5/05 programmable controller. The
HI 1746-WS supports a wide variety of process weighing applications
such as batching/blending, filling/dispensing, check weighing,
force measurement, level by weight and weight rate monitoring.
The module can control two (2) relays via two (2) TTL level outputs
and transmits data via the backplane to the SLC. A 20 bit A-D
converter with 980,000 counts of display resolution gives the
instrument the ability to tolerate large “dead” loads, oversizing
of load cells/sensors and to provide accurate weight measurement
and control.
To calibrate the module, simply push the front panel “Button” to
effect a C2 calibration (electronic), or you can implement a
C2,“Hard” (traditional with test weights) or “Soft (manual load
cell data) through the processor.
