It integrates three 24 V digital inputs and two 0.5 A digital outputs, with a 220 Ω terminating resistor on the RS422 line. The module requires both a 5.2 V ±2% supply for internal logic and a 24 V supply at 1L+ (-3 V) for the I/O side. The 5.2 V supply tolerance (±2%) sets a tight window; the module will not start if the auxiliary 5 V rail drifts beyond that. The 24 V input for I/O is derived from an external source—a supply meeting EN 50155 is specified. The counter input thresholds (signal 1 from +11 V to 28.8 V) match standard 24 V incremental encoders, and the 220 Ω termination is built in, so no external resistor is needed on the RS422 line. The three digital inputs are 24 V sinks with a typical pull current of 9 mA. Both digital outputs are rated 0.5 A per channel with clocked electronic short-circuit protection.","metaTitle":"Siemens 6AG1350-1AH03-2AY0 Counter Module, 200 kHz RS422, EN","metaDescription":"Siemens counter module with RS422 encoder input at 200 kHz, 3 DI, 2 DO, 5.2 V ±2% supply, current production, UL E239877, EN 50155 T1.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":null,"categoryPath":["PLCs (Programmable Logic Controllers)"],"specifications":{"5 V":"Yes; 5.2 V ±2 %","24 V":"Yes; 1L+ (-3 V)","Max.":"60 °C; = Tmax; the rated temperature range of -25 ... +55 °C (T1) applies for the use on railway vehicles according to EN50155","Min.":"-25 °C; = Tmin","Type":"RS 422","Depth":"120 mm","Width":"40 mm","title":"6AG1350-1AH03-2AY0","Height":"125 mm","CE mark":"Yes","EN 50155":"Yes; Sections 4, 5 and 12; no further agreements apply; T1, Category 1, Class A/B, EN 50155:2007","Functions":"1 for gate start, 1 for gate stop, 1 for setting the counter","KC approval":"Yes","UL approval":"Yes; File E239877","description":"***spare part*** SIPLUS S7-300 FM350-1 based on 6ES7350-1AH03-0AE0 with conformal coating, -25…+60 °C, counter module FM 350-1 for S7-300, counter functions up to 500 kHz 1 channel for connection of 5 V and 24 V incremental encoders isochronous mode; measuring range types incl. configuration package on CD-ROM","24 V initiator":"Yes","For Signal \"0\"":"-28.8 ... +5V","For Signal \"1\"":"+11 to +28.8V","Weight, approx.":"250 g","lifecycle_stage":"current","\"0\" To \"1\", Max.":"300 µs","Power loss, typ.":"4.5 W","Rated value (DC)":"24 V; A power supply according to EN 50155 shall be used","Minimum pulse width":"2.5 µs","For Signal \"0\", Max.":"3 V","For Signal \"1\", Min.":"2L+ (-1,5 V)","For Signal \"1\", Typ.":"9 mA","Output current, max.":"400 mA","Terminating resistor":"220 Ω","EAC (formerly Gost-R)":"Yes","Isolation tested with":"500 V","RCM (formerly C-TICK)":"Yes","24 V directional element":"Yes; 1 pulse train, 1 direction level","Counting frequency, max.":"200 kHz","Number of counter inputs":"1; 32 bit or ±31 bit","Number of digital inputs":"3","Required Front Connector":"1x 20-pin","Short-circuit protection":"Yes; Clocked electronically","Number of digital outputs":"2","Differential input voltage":"1,3 V","For Signal \"1\" Rated Value":"0.5 A","Input voltage for signal \"0\"":"-28.8 ... +5V","Input voltage for signal \"1\"":"+11 to +28.8V","from backplane bus 5 V DC, max.":"160 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","from load voltage 1L+ (without load), max.":"40 mA","Installation altitude above sea level, max.":"5 000 m","Limitation of inductive shutdown voltage to":"2L+ (-39 V)","Ambient air temperature-barometric pressure-altitude":"Tmin ...
