Dual flow meter display unit

Programmable flow measurement unit
The programmable A341-28 is designed to simultaneously manage two independent flows, making it suitable for use with flow meters, incremental rotary transducers, proximity switches, and similar devices.

Features and capabilities
The A341-28 impresses with two individually scalable pulse inputs, allowing control over 1, 2, or 4 channels (A, /A, B, /B). This flexibility enables a wide range of applications with input frequencies from 0.01 Hz to 1 MHz per channel.

Multiple measurement modes
Options for single measurement, sum or differential measurement, ratio, or percentage deviation provide versatility across your measurement needs. The linearisation function for each flow measurement ensures precise and accurate results.

Preset parameter sets
For easy configuration, you can predefine up to five independent parameter sets. The 14-bit analogue output offers flexibility with options such as 0/4–20 mA, 0–10 V, and ±10 V, and the unit responds rapidly with a reaction time of less than 1 ms.

Precision and control
Four limit settings with fast-acting transistor switch outputs provide precise process control. The device can be conveniently programmed via the RS232 interface for optimal customisation.

Construction
The A341-28 includes two encoder power supplies rated at 24 VDC / 120 mA and comes in a standard housing measuring 96 x 48 mm with an IP65 protection class. Altogether, it is a versatile unit delivering impressive performance and accuracy.
