PLC Analog Scaling Calculator for 4-20mA and ADC Inputs

Generate engineering-unit scaling formulas for 4-20mA, 0-10V, and common PLC ADC raw ranges used in industrial automation.

4-20mA Loop Voltage Margin Calculator

Check transmitter voltage margin, loop resistance, shunt resistor loading, and cable losses for industrial 4-20mA current loops.

RS-485 Termination and Cable Distance Calculator

Estimate RS-485 and Modbus cable distance, baud-rate limits, node loading, stub length, and 120 ohm termination requirements.

Motor Breaker Sizing Calculator for 3 Phase Induction Motors

Estimate motor full-load current, starting current, breaker rating, and preliminary protection margin for three-phase industrial motors.

Safety Light Curtain Minimum Distance Calculator

Estimate minimum safety distance using detection resolution, approach speed, sensor response, and machine stopping time.

International engineering note

Use these calculators for preliminary review, field troubleshooting, and design comparison. Final selections must be checked against current local standards, project specifications, measured field data, and manufacturer documentation.
