Htl Encoder Input (X81 And X82); Ttl Encoder Emulation Output (X83); Digital Inputs For Position Latch (X84) - ABB FEN-31 User Manual

HTL encoder input (X81 and X82)

+15 V DC ± 20% 200mA (max.) - HTL encoders
Supply voltages +24 V DC ± 20% 200mA (max.) - HTL encoders
External power supply, if connected, has to be in the range of 10-24 V DC
Signal frequencies up to 300kHz can be detected by the HTL encoder input.
Channels A, B, and Z With long cables and/or single-ended encoders it may be difficult to convey high
supported signal frequencies reliably.
Signal levels: "0" < 3.5 V and "1" > 7.5 V
Differential Push-Pull HTL encoders, supply voltage 10 - 24 V
Single-ended Push-Pull HTL encoders, supply voltage 15 - 24 V
