Configurable for a Wide Range of Process and Temperature Signals
The I4P Series offers exceptional versatility, supporting both process and temperature measurements within a single compact unit. It accommodates 4/20 mA, 0/10 Vdc, resistance, potentiometer, and sensor inputs such as thermocouples, Pt, and NTC types. This wide compatibility allows seamless integration into diverse industrial applications, from monitoring pressure and flow to controlling temperature processes, without the need for multiple devices.

Supports 4/20 mA, 0/10 Vdc Outputs and Various Sensor Types
Designed to bridge the gap between analog and digital systems, the I4P supports both current and voltage outputs for flexible signal transmission. It precisely converts readings from thermocouples, RTDs, NTCs, and other sensors into standardized outputs that are compatible with PLCs, controllers, and monitoring systems. This adaptability makes it ideal for mixed-signal environments and for upgrading existing installations.

3-Way Isolation Between Input, Output, and Power
The I4P provides 3000 Veff isolation between its input, output, and power circuits, ensuring complete electrical separation. Isolated transmitters like the I4P prevent ground loops and electrical noise from affecting measurements, which improves accuracy and system stability. They also protect sensitive control equipment from voltage spikes and faults, extending system life and enhancing overall safety.

Front Keypad and Display for Easy Configuration
Setup and maintenance are straightforward with the I4P’s front keypad and digital display. Operators can quickly configure signal ranges, adjust calibration, or monitor input and output values directly on the device without needing external software. Features such as password protection, “Force” test functions, and “SOS” mode make it easy to install, validate, and maintain in demanding industrial environments.

Durable and Flexible Design
The I4P's compact form factor is suitable for DIN rail mounting, making it ideal for integration into existing systems. Its robust casing provides IP30 protection from solid objects and IK06 level impact resistance, ensuring durability in challenging industrial environments.

With its universal power supply range and three-way isolation, the I4P offers not only versatility but also enhanced safety and stability, crucial for maintaining process accuracy and protecting sensitive equipment. Whether for manufacturing, automation, or specialized engineering applications, the I4P Series provides a reliable solution for signal conversion and processing.
