Universal Converter

Product catalog summary

Technical Features
The universal converter supports a wide range of inputs including thermocouples (types J, K, R, S, T, B, E, N), RTD (PT100, PT500, PT1000, Ni100) with 2, 3, or 4 wire connections, voltage (-150 to +150 mV, -30 to +30 V), current (-24 to +24 mA), and potentiometer (500 Ω to 10 KΩ). It outputs a 4 to 20 mA signal and is loop powered with a power supply range of 7 to 30 Vdc. The device features galvanic isolation of 1.5 kVac and operates within a temperature range of -20 to +65°C.

General Features
The converter is designed with a single input and output channel, consuming less than 660 mW of power. It is equipped with spring clamp connections compliant with EN 60175 standards and holds approvals from CE, EN 61000-6-4, EN 64000-6-2, and EN 61010-1.

Input Specifications
The device supports various input types with specific impedance values: thermocouples and voltage inputs have an impedance of 10 MΩ, while current inputs have an impedance of 40 Ω. The RTD/resistance inputs use an excitation current of 375 µA. The device includes cold junction compensation for thermocouples and settable fault sensor detection.

Output Specifications
The output is a loop-powered 4 to 20 mA signal with a load resistance of 1 KΩ at 28 Vdc and 21 mA. The resolution is 2 µA (< 13 bit), with output adjustments for over-range and fault conditions.

Configuration and Programming
Configuration is performed via the EASY-LP software using the S117P USB adapter. The software allows for easy setup and programming of the device.

Physical and Environmental Specifications
The converter measures 6.2 x 93.1 x 102.5 mm and operates within a temperature range of -20 to +65°C.

Order Information
The model K121 is the universal converter, and the programming kit includes the Easy-LP software and USB adapter.
