Signal Isolators – these products are for typical facility-based analog current and voltage signals. They eliminate the measurement errors caused by ground loops or electromagnetic interference. They can also be used to boost weaker signals resulting in increased transmission distance or to allow additional devices to be connected to loop calibrators. The signal isolator is powered from the input/output current loop, or from a separate auxiliary power supply.

Signal Transmitters – these products convert, filter and isolate any low-level signals coming from typical measuring devices. This includes mV signals from thermocouples and PT100 measurement probes, which are converted into normalized current or voltage signals. This range of products includes not only simple and conventional modular versions, but also highly-flexible microprocessor-controlled versions.

Process Alarms – these are special two-channel modules which monitor facility-specific measurement values. When necessary, they issue alarms to external monitoring systems. Versions are available for all standard input signals. The setpoint values can be set with an operating panel located on the front. Microprocessor-controlled modules are available for more complex applications. They are equipped with standard timing delays, filter functions, setpoint adjustments and displays.

Multi-Channel Processing Modules – these are compact modules which are capable of processing multiple inputs, outputs and alarms simultaneously. When necessary, they can transmit analogue or digital values, based on certain results, to a control system. They are suitable for the remote monitoring of processes. With their use, cycle times can be shortened within the application and the number or I/O devices can be reduced. This will also lead to a reduction in the costs surrounding installation, cabling, initial commissioning and maintenance.

Indicators and Configurable Displays – these are available in a variety of designs. This includes products ranging from simple versions powered by current loops, to configurable products with integrated analogue and alarm outputs.

Calibration Devices – these complete the product offering. They are specially designed for the calibrating and setting of analogue signal-processing devices. They provide clean smoothed standard signals and make use of a load indicator for quick loop diagnostics.
