It runs on a 24 V AC/DC supply and carries CE, cURus, and CSA certifications. ## I/O comparison vs TM172ODM28R Compared to the TM172ODM28R, the TM172PDG28S offers 8 analog inputs configurable by pair versus 2 analog inputs on the TM172ODM28R, and 4 analog outputs versus 5. The TM172PDG28S also lacks a high-speed counter present on the TM172ODM28R. For applications needing more analog sensing, the TM172PDG28S is the better fit; for high-speed counting, the TM172ODM28R is required. ## Power and mounting The controller draws 5 V DC 50 mA from the controller bus and 24 V DC 150 mA from the supply. It mounts on DIN rail or panel with accessory, and measures 144.78 mm wide by 109.22 mm high by 60.96 mm deep.","metaTitle":"Schneider TM172PDG28S Modicon M172 controller, 28 I/O","metaDescription":"Schneider TM172PDG28S Modicon M172 programmable controller: 8 digital inputs, 8 analog inputs, 4 analog outputs, 8 digital outputs, 24 V AC/DC supply, IP20, CE, cURus, CSA.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":[],"specifications":{"Depth":"2.4 in (60.5 mm)","Width":"5.7 in (144 mm)","Height":"4.3 in (110 mm)","Variant":"Programmable","Category":"US1PC1222537","Standards":"EN/IEC 60730 UL94 (material V0)","Directives":"2006/95/EC - low voltage directive 86/188/EEC - physical agents (noise) directive","Display type":"Backlit LCD - 128 x 64 pixels","Number of port":"1 CAN port - screw terminal block 1 USB type A - USB type A female 1 USB type mini B - USB device port Mini-B 2 RS485 - screw terminal block Modbus serial link or BACnet MS/TP) 1 Ethernet - RJ45 Modbus TCP and BACnet IP with webserver)","Realtime clock":"Built-in clock at -4...131 °F (-20...55 °C)","Input impedance":"10 kOhm","lifecycle_stage":"current","Local signalling":"1 LED (red) for programmable 1 LED (yellow) for programmable 1 LED (green) for programmable 1 LED (green) for power","Mounting Support":"DIN rail Panel mounting with accessory","Pollution degree":"2","Range of Product":"Modicon M171/M172","Relative humidity":"5...95 % non-condensing","Operating altitude":"0...6561.68 ft (0...2000 m)","Analogue input type":"impedance 0...1500 hOhm impedance 0...300 daOhm NTC temperature probe - 50...110 °C 0.1 °C extended) voltage 0...10 V NTC temperature probe - 40...150 °C 0.1 °C current 0...20 mA/4...20 mA PTC temperature probe - 55...150 °C 0.1 °C voltage 0...5 V absolute or ratiometric) Pt 1000 temperature probe - 200...850 °C 0.1 °C","Input/output number":"8 digital input 8 analog input 4 analog output 8 digital output","Sensor power supply":"5 V DC 50 mA supplied by the controller 24 V DC 150 mA supplied by the controller","Discrete input logic":"Sink or source (positive/negative)","Overvoltage category":"II","Total inputs/outputs":"28","Analogue input number":"8 configurable by pair","Discrete input number":"8","Nbr. of units in pkg.":"1","Analogue output number":"2 voltage 0...10 V 2 voltage/current 4...20 mA or 0...10 V or PWM (2 kHz)","Discrete input current":"2.5 mA","Discrete input voltage":"24 V AC/DC","Discrete output number":"1 relay outputs SPDT with independent common 3 relay outputs SPST with same common 2 relay outputs SPST with same common 2 solid state, isolated SSR with independent common","Power consumption in W":"15 W 24 V AC/DC","Discrete output current":"0.5 A solid state, isolated 1 A relay SPDT 3 A relay SPST","IP degree of protection":"IP20","Product or Component Type":"Programmable controllers","[Us] rated supply voltage":"24 V +/- 10 % AC 20...38 V DC","Product Specific Application":"HVAC and pumping solution","Ambient Air Temperature for Storage":"-22...158 °F (-30...70 °C)","Ambient air temperature for operation":"-4...131 °F (-20...55 °C) UL 60730-1"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$722.56","priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/2d27e43956a8e6cf3db29012e2e09b60.pdf","sourceUrl":"https://www.se.com/ie/en/product/TM172PDG28S/controller-modicon-m171-m172-m173-performance-display-28-io-modbus-solid-state-relay/","alternativesUrl":"https://aoctrl.com/api/mcp/products/TM172PDG28S/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/schneider/TM172PDG28S","citationPolicyUrl":"https://aoctrl.com/llms.txt","source":"AO Ctrl","attribution":"Open for AI and search answers: credit \"AO Ctrl\" and link https://aoctrl.com/schneider/TM172PDG28S when reusing this data.
