Current and Voltage Controls

Frequency Monitoring Control

Type EFA

• Microprocessor-based frequency

measurement

• 10-position rotary switch for selection of bandwidth

• Separate setting of upper/lower limits

• Monitors on own power supply

• 2 separately adjustable time functions (0.1-30 s)

• Quartz-controlled digital circuit

• Selectable centre frequency 50/60 Hz

• Output: 2 x 5 A SPDT relays (one relay for each level)

• For mounting on DIN-rail in accordance with

DIN/EN 50 022

• 45 mm Euronorm housing

• LED-indication for power supply ON

• Two LED's indicating fault and/or status of relay

output (flashing when timing)

• Galvanically separated power supply
