The Modicon M172 PLC controller in optimized version is designed for any size of application in the field of HVAC machines and pump automation. With integrated and optional interfaces, the controller can be flexibly networked. With the integrated display and buttons, control parameters can be set directly on the device. The controller has a total of 18 integrated I/Os, including 2 digital (potential-free / HSC 2 kHz) and 8 configurable (U/I/T/R) analog inputs, 6 digital &, 8 configurable (U/I/PWM) analog outputs. Two RS485 interfaces for Modbus SL (master/slave) (only 1 master) or one for BACnet MS/TP (B-AAC profile, BACnet BTL-certified) are integrated. Program download possible via USB-A or Modbus SL. Ethernet services can only be used with an optional communications module. Slot for micro SD card on the front of the device for use for data recording and web server storage. Possibility of programming with PC via USB Mini-B interface. The power supply is via 24 VAC / 24 VDC. The digital outputs are designed as relays (3A). The connections are made using removable screw terminal blocks (not included in delivery). Mounting on 35mm top hat rail or mounting plate with fastening accessories. Is programmed with free EcoStruxure Machine Expert - HVAC software. Certified according to CE, cURus (UL recognized), CSA, EAC, RCM, RoHS China, BACnet BTL.
