19. Analogue sensor module
Installation
Connection diagram
Follow the steps below to install the module:
1 Press the module onto the DIN rail until it clicks into place. Preferably position the module in the top row inside the
electrical cabinet to keep the SELV cables separate from the 230 V cables.
2 Connect the sensors to one of the screw terminals 1-3.
3 Connect the mass of the sensors to the common screw terminal COM.
4 Connect the analogue sensor module to the module before it. Slide the sliding contact of this module to the right
until it clicks into the analogue sensor module. This will ensure that the bus and the power supply voltage are
connected.
• Ensure that the installation is disconnected from the mains.
• The distance between the sensors and the module should not exceed 100 m.
• A maximum of three sensors can be connected per module. Up to 10 modules can be connected per
installation.
• Always use sensors that are suitable for applications with a safety extra-low voltage (SELV).
• If the sensor uses an SELV (24 Vdc) power supply, then it is always suitable.
• If the sensor uses a 230 Vac power supply, then it must have a galvanically isolated output (SELV).
