POL871.61/STD - Siemens Climatix Operating unit; buttons, 8-line Unicode display, backlight; magnetic back, IP65

The Siemens POL871.61/STD is the HMI-TM (Human Machine Interface Touch Mobile) operating unit for the Siemens Climatix controller range. Designed for advanced on-site operation, it provides a high-resolution backlit display and full access to data points, system configuration, and alarm management on Climatix POL4xx and POL6xx controllers.

Rated IP65 across the entire housing, the POL871.61 is suitable for use outside the control panel as a portable mobile unit or for magnetic mounting directly to the controller or panel door. It connects via the controller's local HMI port using the integrated 2.5 m spiral cable (RJ45), powered directly by the controller with no separate supply required.

Key Features:

• High-resolution 240 x 128 dot-matrix STN blue LCD with white LED backlight
• 6 navigation keys with dedicated ALARM, INFO, and CANCEL keys with LEDs
• IP65 protection across the entire unit, suitable for use outside the control panel
• Magnetic mounting and mobile operation via integrated 2.5 m spiral cable
• Powered directly by controller via local HMI connection (DC 24 V, 60 mA), no separate supply
• User passwords are configurable per access level
• Multi-language support
• Full data point access and local HMI settings
• Firmware upgradeable

Compatible Controllers The POL871.61 connects to Climatix POL4xx and POL6xx series controllers via the RJ45 local HMI port. For permanent panel installation, see the POL871.62/STD panel-mount variant.
