It provides two 32-bit (or ±31-bit) counter inputs with a maximum counting frequency of 200 kHz, making it suitable for high-speed position or pulse counting from incremental encoders. The module integrates 6 digital inputs and 4 digital outputs, plus a dedicated RS 422 encoder interface for differential signals. The encoder supply is 5.2 V ±2 % from the module's own 5 V rail, and the 24 V field supply is 1L+ (-3 V). ## Counter inputs and encoder interface Each counter input accepts differential RS 422 signals with a minimum differential voltage of 0.5 V. The module supports one pulse train with one direction level per channel, and the minimum pulse width is parameterizable: ≥2.5 µs at 200 kHz or ≥25 µs at 20 kHz. The 24 V digital inputs have a signal \"1\" threshold of +11 to +28.8 V, and the 24 V digital outputs are rated 0.5 A per channel with clocked electronic short-circuit protection. The module also provides a 220 Ω terminating resistor for the RS 422 line. Diagnostics include a parameterizable diagnostic alarm, a hardware interrupt, and status indicators: 14 green LEDs for CR, DIR, inputs, and outputs, plus red LEDs for external fault (EXTF) and internal fault (INTF).","metaTitle":"Siemens 6ES7450-1AP01-0AE0 FM 450-1 Counter Module, 200 kHz","metaDescription":"Siemens 6ES7450-1AP01-0AE0 FM 450-1 counter module for S7-400. 2 counter inputs at 200 kHz, 6 DI, 4 DO, RS 422 encoder interface.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"NRND","categoryPath":["Digital Output Modules"],"specifications":{"5 V":"Yes; 5.2 V ±2 %","24 V":"Yes; 1L+ (-3 V)","Type":"RS 422","Depth":"210 mm","Width":"25 mm","Height":"290 mm","Functions":"1 for gate start, 1 for gate stop, 1 for setting the counter","24 V initiator":"Yes","For Signal \"0\"":"-28.8 ... +5V","For Signal \"1\"":"+11 to +28.8V","Parameterizable":"Yes","Weight, approx.":"650 g","lifecycle_stage":"mature","\"0\" To \"1\", Max.":"300 µs","Diagnostic alarm":"Yes; Parameterizable","Power loss, typ.":"6 W","Rated value (DC)":"24 V","Status indicator":"Yes; 14 green LEDs for status of CR, DIR, inputs and outputs","Hardware interrupt":"Yes; Parameterizable","At \"0\" To \"1\", Max.":"2.5 µs; ≥ 2.5 µs (200 kHz); ≤ 25 µs (20 kHz)","Minimum pulse width":"≥ 2.5 µs (200 kHz); ≥ 25 µs (20 kHz) (parameterizable)","Diagnostics function":"Yes","For Signal \"0\", Max.":"3 V","For Signal \"1\", Min.":"2L+ (-1,5 V)","For Signal \"1\", Typ.":"9 mA","Output current, max.":"300 mA","Terminating resistor":"220 Ω","Isolation tested with":"500 V","24 V directional element":"Yes; 1 pulse train, 1 direction level","Counting frequency, max.":"200 kHz","Number of counter inputs":"2; 32 bit or ±31 bit","Number of digital inputs":"6","Required Front Connector":"1x 48-pin","Short-circuit protection":"Yes; Clocked electronically","Number of digital outputs":"4","external fault EXTF (red)":"Yes","internal fault INTF (red)":"Yes","Differential input voltage":"min. 0.5 V","For Signal \"1\" Rated Value":"0.5 A; Res. / P.D. 5 W tungsten 24 V DC","Input voltage for signal \"0\"":"-30 to +5 V","Input voltage for signal \"1\"":"+11 to +30V","Diagnostic information readable":"Yes","from backplane bus 5 V DC, max.":"300 mA","Incremental encoder (symmetrical)":"Yes; With 2 pulse trains offset by 90°","Incremental encoder (asymmetrical)":"Yes","Input current for signal \"1\", typ.":"9 mA","permissible range, lower limit (DC)":"20.4 V; Dynamic 18.5 V","permissible range, upper limit (DC)":"28.8 V; dynamic 30.2 V","Between The Channels And Backplane Bus":"Yes; Optocoupler","Status indicator digital input (green)":"Yes","Status indicator digital output (green)":"Yes","from load voltage 1L+ (without load), max.":"50 mA","from load voltage 2L+ (without load), max.":"60 µA","Limitation of inductive shutdown voltage to":"2L+ (-39 V)","Input frequency (with a time delay of 0.1 ms), max.":"200 kHz","for signal \"1\" permissible range for 0 to 60 °C, max.":"0.6 A","for signal \"1\" permissible range for 0 to 60 °C, min.":"5 mA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$783.59 – $1,129.00","priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":"https://support.industry.siemens.com/webbackend/api/ProductSupport/TechnicalData?language=en&region=cn&productId=404289&mlfb=6ES7450-1AP01-0AE0","alternativesUrl":"https://aoctrl.com/api/mcp/products/6ES7450-1AP01-0AE0/alternatives.json"},"ai":{"faq":[{"question":"How many counter inputs does the 6ES7450-1AP01-0AE0 have?","answer":"The module has 2 counter inputs, each 32-bit or ±31-bit, with a maximum counting frequency of 200 kHz.
