Signal Conditioner : SEM 1600F

DIN Rail frequency / Pulse conditioner
  • Dual or single universal frequency inputs sensor excitation
  • Frequency (0.01 to 65000) Hz counter (DC TO 1000) hZ)
  • Rate, totalise, k factor, m factor, maths
  • Relay output
  • mA, voltage, bipolar voltage output

This signal conditioner accepts frequency and pulse sensor outputs with a frequency range between (0.01 to 65000) Hz in standard configuration and (DC to 1000) Hz in counter mode. Typical applications would be to measure flow or batch counting.

The product has a built-in capability to operate as a dual input which allows differential flow/count measurement with advanced maths functions. Or as a single channel input, with an external reset contact.

When operated in signal channel mode, the discrete input can be programmed to reset the total counter, batch counter or latched relay. The input can also be programmed to control the total counter direction with a combination of count-up, count-down or halt modes available.


Basic frequency mode to process signal mode, analogue + relay outputs.
Advanced frequency mode with K factor, M factor, totalize, rate, maths functions, process signal, 12-point user linearisation for channel A using meter correction, analogue + relay outputs.
Pulse counter mode with K factor, totalize, maths functions, process signal, analogue + relay outputs.
USB CONFIGURATION The product uses a built-in USB port for configuration, together with a simple to use, free menu-driven software configuration tool, allowing the user to take advantage of the products’ comprehensive specification.

ANALOGUE OUTPUT The output stage offers either voltage, bipolar voltage or active/passive current re- transmission signals. The output signal can be ranged to a scale anywhere within the process range.

RELAY OUTPUT A volt free output contact is provided capable of operating as either a trip relay, latched relay or pulsed relay. High and low-level relay functions are also available. Trip options on rate, count, totalize or maths functions.

SIGNAL RETRANSMISSION SCALING The input signal range for retransmission can be selected from any part of the maximum input capability. The output signal range can be selected from any part of the total output capability, for example (0 to 12) litres per minute input to (1 to 5) mA output.

Overall, this frequency / pulse signal conditioner is an extremely powerful product and is designed and built in the UK.
