F741-M

Panel Mounting Type Loadcell Indicator
 

Product Outline

F741-M is a loadcell indicator with importance attached to field operability that of simple design with useless functions eliminated.

A large high-intensity fluorescent display tube for displaying easy-to-read characters of 20 mm in height, large, maneuverable key switches, and operation by menu selection method. F741-M is of simple design with useless functions eliminated. This is a loadcell indicator with importance attached to field operability. With a low drift of 0.2μV/°C, high-speed A/D conversion at 50 times/sec, a high display resolution of 1/10000, and a worldwide voltage range (AC85 to 242V, 4 steps selectable), no compromises in its performance have been made.

INPUT/OUTPUT SECTION
External input signal Tare subtraction (TARE ON)
ON when shorted to COM terminal by contact (relay, switch) or non contact (transistor, open collector).
External output signal Transistor’s open collector output (Emitter=COM terminal)
Output is LO when transistor is ON.
Output conditions - HI: Net weight >= HI set value
- GO: LO set value <= net weight <= HI set value
- LO: Net weight < LO set value interface
