Product Data Sheet

This logic controller is part of the Modicon M171/M172/M173 range, a control offer for HVAC/Pumping applications. This controller figures 6 digital inputs, 5 configurable analog inputs, 6 digital outputs, 5 analog outputs, and a display. This programmable controller embeds 2 communication ports for RS485 and LAN expansion bus. It is a programmable logic controller for HVAC and Pumping applications, equiped with a LCD display. DIs are volt free in 1 group, AIs are NTC, 0-20mA, 4-20mA, 0-10V, 0-5V, 0-1V. DOs are SPST (2A, 230Vac) with the same common,SSR (3A, 230Vac), or open collector, AOs are open collector for 12V PWM/PPM, or 0-10V. It measures 70.2mm wide, 61.6mm deep, 87mm high, and weighs 0.190kg. This controller is designed for HVAC solutions. It is certified by CE, CURus, CSA and EAC. It is compatible with screw terminal blocks, and communication modules. It is sold in a 1-piece package. It is designed for 35mm rail mounting. Modicon M171/M172/M173 controllers are designed for complete automation solutions for HVAC and Pumping machines. Modicon M171/M172/M173 range is for OEMs and helps to maximize profitability or energy efficiency in HVAC applications.
