SA640: Dual Frequency Meter 6 digit with 4 Relays and Analog Output

SKU: sa640-dual-frequency-meter-6-digit-with-4-relays-and-analog-output Category:


The SA640 serves as a speed display, tachometer, frequency meter or timer. The device offers various programmable operating modes for speed, baking time (reciprocal speed), total or differential speed, speed ratio or percentage deviation with two signal inputs for the connection of incremental rotary pulse generators, proximity switches or light barriers. High input frequencies up to 1 MHz can be processed. In addition, the device is equipped with a serial RS232 interface, which can be operated both in PC and printer mode. The intuitive menu is used to preselect four limits, which enable a switching function via 4 fast transitor outputs as well as an additional 4 potential-free changeover relay outputs.

In contrast to the SD640, the SA640 also has a 14-bit analog output for selective operation with voltage or current.

  • 2 scalable inputs with format A, /A, B, /B
    [HTL / TTL / RS422, single channel, dual channel,
    symmetric or asymmetric]

    [10 … 30 VDC]
  • Input frequency up to 1 MHz
  • Scalable 14 bit analog output ±10 V or 0/4 … 20 mA
  • 4 fast transistor outputs with push-pull characteristic,
    short-circuit-proof [5 … 30 VDC]
  • 4 output relays with potential free change-over contact
  • 4 programmable preset values
  • Power supply 24 VAC and 17 … 40 VDC
  • Compact norm panel housing
  • LED display 6 digits with 15 mm height
  • Display range -199999 … 999999
  • Serial RS232 interface
  • Dimension B x H x T = 96 x 90 x 140 mm (3.78 x 3.78 x 5.51 “)
