OMRON F159 Load Cell Interface - PLC-Based Process Controllers

Small, Fast and Flexible Weigh-based Process Control

Weigh-based Process Control can be established by integrating F159 Special I/O Unit into SYSMAC CJ1. F159 provides direct Load Cell connection.

In addition, it provides pre-programmed functions, e.g. Zero Tracking, Auto Free-fall Compensation and etc. An ideal solution for various process weighing application.

Features

Specifications that can be offered only by the well-versed Unipulse-all mobilized into the a small body, is the new weighing solution High Speed A/D Conversion with High Resolution A 500 times/sec high-speed conversion to counter fluctuations in weight value. Also, when it is set to the 1/4 scale division compliance to the Weight and Measurement Law, it guarantees 1/10000 display resolution at all input range (1/40000 when not set at 1/4 scale division). Its accuracy is most desired by demanding weighing requirements. Weighing Sequence Function By only entering the setting instruction, feeding and discharging gate can be directly controlled. All weighing control is performed by F159 Load Cell Interface to lighten CJ1 load so that a high-speed weighing and control line can be set-up without it being affected by CJ1 command timing. Auto Free-fall Compensation F159 Load Cell Interface automatically compensates fluctuations in actual free fall, which is one of the biggest factors that causes weighing error. Gravitational Acceleration Compensation Even when calibration site and installation site are at different locations, calibration can be completed by just setting the gravitational acceleration of the installation site. There is no further need to perform re-calibration at the installation site. Zero Tracking The slow zero drift, which is caused by temperature fluctuation, and the zero point shift are automatically compensated. Powerful Filters to Eliminate Mechanical Vibrations Installed with Bessel low-pass filter, which has powerful damping characteristics, and moving average-type digital filter.
