Frequency measurement and display, with control signal outputs. Control signals are issued on two independent channels.
ИЦ406 frequency meter / tachometer
Purpose and principle of operation:
- Frequency measurement and display, with control signal outputs.
- Used in automated systems for monitoring and measuring alternating current (voltage), pulse frequency and rotational speed.
- Control signals on two independent channels.
- Additional control input
Distinctive features:
- Control input versions:
- application of AC voltage;
- application of voltage pulses;
- closing external contacts. - An adjustable multiplier allows the measured frequency to be displayed in whatever units and scale are required.
- Outputs — isolated changeover contacts on each channel.
- An additional digital input extends the use of the frequency meter in automation and monitoring systems.
- Parameters programmed using the front-panel buttons.
- Password protection against reprogramming.
- The measured value is shown on a three- or four-digit display.
- Communication with the supervisory system over RS485 using Modbus (optional).
- Powered from a DC or AC supply.
- Galvanic isolation between the supply input, the control inputs and the output contacts.
