External input/output modules for control units

External input/output modules allow control units to be expanded with additional sensors and control elements. They ensure flexible device connectivity and reliable data collection and control in a variety of applications.

AIM600, AIM615 - 4-20 mA/RS485 Converters

AIM600, AIM615 - 4-20 mA/RS485 Converters

The AIM600 and AIM615 transducers are characterized primarily by high measurement accuracy provided by the 24-bit converter, as well as low quiescent current consumption, a supply voltage suitable for operation from a 12 V battery, galvanic isolation of the inputs from both the supply voltage and the RS485 communication line, and, last but not least, high operational reliability without any mechanical adjustment elements.

B3OK – ISCO Converter

B3OK – ISCO Converter

The B3OK converts the three binary outputs of ISCO devices to inputs for FIEDLER telemetry units (H1, H3, and others). It enables simple and secure connection of ISCO devices to data logging and control systems without the need for additional modules.

H520-B - Level Display Module

H520-B - Level Display Module

The H520-B display module is designed to provide an approximate indication of the liquid level. The module does not contain a liquid level sensor; it merely displays the liquid level data received from a connected control system via the RS485 bus.
