High-Precision Industrial Signal Converters & Isolators
A high-precision Signal Converter translates industrial current signals into readable voltage or digital formats. As a core component of our industrial signal isolators series, these devices provide robust electrical isolation. They eliminate ground loops and filter out electromagnetic interference. This ensures seamless compatibility between field sensors and central control systems like PLCs. Whether upgrading a facility or designing a new network, our converters deliver reliable accuracy for demanding process environments.
Explore Our Signal Converter Series
Our comprehensive range of signal conversion modules meets diverse industrial measurement and control requirements. These devices feature modular designs, standardized form factors, and robust internal circuitry. They offer dependable performance across various applications. Explore our specialized categories to find the exact module for your automation infrastructure.
4-20mA Analog Signal Converters
Our standard analog converters function as highly accurate isolating amplifiers. Designed for modern control cabinets, they feature convenient DIN rail mounting. Their low installation width maximizes space efficiency. These modules maintain high accuracy in harsh process environments. They ensure critical analog data is transmitted without degradation or signal loss.
RTD & PT-100 Temperature Signal Converters
Accurate thermal monitoring requires specialized transducers designed for temperature measurement. These converters seamlessly translate RTD and PT100 sensor outputs into standard 4-20mA or voltage signals. They linearize the temperature curve and provide galvanic isolation. This protects sensitive control equipment while delivering precise readings for industrial heating and cooling systems.
Digital & Protocol Signal Converters (Modbus, HART)
For advanced automation networks, we offer digital converters with extensive protocol and software customization capabilities. These intelligent modules support industry-standard communication protocols like Modbus-RTU, Modbus-TCP, and HART. They bridge the gap between analog field devices and digital control architectures. This enables remote diagnostics, parameter configuration, and seamless SCADA integration.

Signal Converter Selection Guide: How to Choose the Right Module
Selecting the appropriate signal converter is vital for maintaining system accuracy and safety. First, consider the specific input and output requirements of your field devices. You must also account for environmental conditions and required isolation levels. Additionally, determine if you need advanced safety features like intrinsically safe barriers for hazardous areas. Specialized inputs, such as potentiometer resistance transmitters, may also be necessary.
| Selection Factor | Key Considerations | Impact on Performance |
| Input/Output Type | 4-20mA, 0-10V, RTD, Thermocouple, Frequency | Ensures hardware compatibility between the field sensor and the receiving PLC/DCS. |
| Isolation Level | 2-way or 3-way galvanic isolation, voltage rating | Prevents ground loops, protects against voltage spikes, and reduces signal noise. |
| Protocol Compatibility | Analog only, Modbus-RTU, Modbus-TCP, HART | Determines the ability to transmit digital diagnostics and integrate with SCADA systems. |
| Installation & Environment | DIN rail mounting, operating temperature range, housing width | Dictates cabinet space requirements and reliability in extreme industrial conditions. |
