It provides 22 I/O points: 6 digital inputs (sink or source logic), 6 digital outputs (1 open collector, 3 relay SPST common, 2 relay SPST independent), 5 analog inputs (voltage 0–10 V, ratiometric 0–5 V, NTC, 0–20/4–20 mA), and 5 analog outputs (3 voltage 0–10 V, 2 PWM/PPM 20 kHz). The controller is blind (without display), DIN-rail mounted, rated IP20, and complies with EN/IEC 60730 and the low voltage directive 2006/95/EC. The TM171OB22R is a programmable controller, whereas the TM171EO22R is an Additional I/O module — the same 22 I/O count (5 analog output, 6 digital input, 5 analog input, 6 digital output) but the TM171OB22R runs as a standalone logic engine, not an expansion slice. ## Lifecycle","metaTitle":"Schneider TM171OB22R Modicon M171/M172/M172 Blind Controller, 22 I/O","metaDescription":"Schneider Modicon M171/M172/M173 TM171OB22R programmable controller, 22 I/O (6 DI, 6 DO, 5 AI, 5 AO), 12/5 V DC, DIN rail, IP20, EN/IEC 60730.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":[],"specifications":{"Depth":"2.4 in (61.6 mm)","Width":"2.8 in (70.2 mm)","Height":"3.4 in (87 mm)","Variant":"Programmable","Category":"US1PC1222537","Standards":"EN/IEC 60730","Directives":"86/188/EEC - physical agents (noise) directive 2006/95/EC - low voltage directive","Display type":"Without Display","Contacts usage":"Volt-free contacts","Number of port":"1 LAN expansion bus","Realtime clock":"Built-in clock at -4...131 °F (-20...55 °C)","lifecycle_stage":"current","Mounting Support":"DIN rail","Pollution degree":"2","Range of Product":"Modicon M171/M172","Relative humidity":"10...90 % non-condensing","Analogue input type":"voltage 0...5 V ratiometric) voltage 0...10 V NTC temperature probe - 50...100 °C 0.1 °C current 0...20 mA/4...20 mA voltage 0...1 V","Input/output number":"5 analog output 6 digital input 5 analog input 6 digital output","Sensor power supply":"12 V DC 85 mA 5 V DC 20 mA","Discrete input logic":"Sink or source (positive/negative)","Overvoltage category":"II","Total inputs/outputs":"22","Analogue input number":"2 configurable 3 analog input NTC","Discrete input number":"6","Nbr. of units in pkg.":"1","Analogue output number":"3 voltage 0...10 V 2 PWM/PPM 20 kHz, 12 V, 35 mA","Discrete output number":"1 open collector 3 relay outputs SPST with same common 2 relay outputs SPST with independent common","Power consumption in W":"4 W 100...240 V AC","Discrete output current":"2 A relay","IP degree of protection":"IP20","Product or Component Type":"Controller","[Us] rated supply voltage":"24 V 12...24 V AC","Product Specific Application":"HVAC and pumping solution","Ambient Air Temperature for Storage":"-40...185 °F (-40...85 °C)","Ambient air temperature for operation":"-4...131 °F (-20...55 °C) UL 60730-1"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$90.17","priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":null,"alternativesUrl":"https://aoctrl.com/api/mcp/products/TM171OB22R/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/schneider/TM171OB22R","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/TM171OB22R when reusing this data.
