The tekmar 005 0-135 Ohm Converter is a device for altering the signal of a modulating boiler control. It converts a 4-20 mA signal into a 0-135 ohm resistance signal. This allows you to use tekmar Boiler Controls that do not produce a 0-135 ohm signal with modulating boilers that require a 0-135 ohm signal.
