4.2 Compatible Input Devices

The smart card supports the following types of input devices:
• Analog 4–20 mA active (self-powered) and passive (loop-powered)
• Pulse
• Digital switch
4.3 Active and Passive 4–20 mA Input Devices
The wiring connections for 4–20 mA sensors vary depending on how the sensor is powered. This manual describes the wiring
connections for passive (loop-powered) sensors, but active (self-powered) sensors can also be used by changing the wiring
connections.
• Passive (loop-powered) sensors are powered from the 4–20 mA terminals of the smart card. For these sensors, use B13-B14, B23-
B24, B33-B34.
• Active (self-powered) sensors have either an internal or external power supply. The sensor is not powered from the smart card
terminals. For these sensors, connect the 0 V to terminal R1 and connect the active input to B13, B23, or B33 as required.
