The Modicon M171 PLC controller in optimized version is designed for simple and compact applications in the field of HVAC machines and pump automation. Thanks to its small design, it can be used in a space-saving manner. With the integrated display and buttons, control parameters can be set directly on the device. The controller has a total of 14 integrated I/Os, including 5 configurable (U/I/T) analog inputs, 4 digital and 5 configurable (U/I/PWM/PPM) analog outputs. The power supply is via 100 VAC to 240 VAC. The digital outputs are designed as relays (2A / 230VAC). The connections are made using removable screw terminal blocks (not included in delivery). Mounted on 35mm top hat rail. Is programmed with free EcoStruxure Machine Expert - HVAC software. Certified according to CE, cURus (UL recognized), CSA, EAC, RCM, RoHS China.
