3.7 RAD-DO8-IFS - digital extension module with eight
outputs
The digital RAD-DO8-IFS I/O extension module processes up to eight digital output signals
that are switched via transistor outputs. The eight outputs are arranged in two groups of four
outputs each with a common electrical supply. The two output groups are electrically
isolated from one another, from the supply voltage, and from the electronics.
Since the DO1 ... DO4 and DO5 ... DO8 output groups are electrically isolated, the digital
outputs must be externally supplied (see Figure 3-33).
• The DO1 ... DO4 outputs are supplied via:
– Terminal 1.1 (12 V DC ... 30.5 V DC)
– Terminals 1.2/1.3 (GND)
• The DO5 ... DO8 outputs are supplied via:
– Terminal 6.1 (12 V DC ... 30.5 V DC)
– Terminals 6.2/6.3 (GND)

Use the I/O extension modules in connection with the RAD-900-... wireless module,
firmware version 1.40 or later. You can update the firmware free of charge using the
PSI-CONF software, Version 2.04 or later.
The firmware and software can be found on the Internet at
phoenixcontact.net/products.
