Phoenix Contact RAD-IN-4A-I 4-Channel 4–20 mA Analog Input Module

Phoenix Contact RAD-IN-4A-I Analog Input Extension Module

The Phoenix Contact RAD-IN-4A-I is an analog input extension module designed to acquire four 4–20 mA current signals within Radioline bidirectional wireless systems. It connects to the system via a bus foot connector, supplying power and enabling internal data communication.

Analog Signal Acquisition

• Four analog input channels for 4–20 mA current signals
• 16-bit resolution for precise signal acquisition
• Input resistance less than 170 Ω
• 24 V DC sensor supply available at terminal connections

System Integration and Configuration

The module uses a rotary switch with positions 1 through 8 to assign channel mapping with a corresponding RAD-OUT-4A-I output module. Signal transmission and pairing occur automatically once matching addresses are configured.

Industrial Applications

• Wireless transmission of analog process signals
• Industrial automation and monitoring systems
• Hazardous location installations (Class I, Division 2)
