ИЦ406С
Digital panel frequency meter for monitoring AC mains frequency

Purpose:

• Frequency measurement and display.
• Control signals on two independent channels (optional).

Distinctive features:

• 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 and the measuring input.

Technical specifications:

• Frequency measuring range, Hz: 20.00-70.00
• Input voltage, V: 5-50; 10-100; 100-600
• Supply voltage range:
  - AC at 50 Hz, V: 85 ÷ 265
  - DC, V: 60 ÷ 350
• Power consumption no more than 2 W
• Overall dimensions: 72×72×97 mm
• Panel cut-out size: 68×68 mm
• Digit height: 14 mm
• Display colour (to order): red, green or yellow
• Permissible voltage between the supply input and the measuring input: 1000 V
• Operating temperature range, °C: -40 ÷ +55
• Protection rating per EN 60529/IEC 529:
  - electronic unit IP40
  - terminal block IP20
• Mounting method and method of connecting external leads:
  - for front-panel mounting;
  - supply conductors connected via terminal blocks.
• By agreement with the customer, frequency meters can be supplied with up to 6 digits, a different measuring range, a different input voltage range, or a 5 V DC/AC supply.
