I/O Systems - S800 I/ODP820

DP820 is an two-channel pulse counting module for incremental pulse transmitters up to 1.5 MHz. Each channel contains counters and registers for position/length and speed/frequency measurement. Each channel provides three balanced inputs for connection of a pulse transmitter, one digital input and one digital output. Pulse transmitters with RS422, +5 V, +12 V, +24 V and 13 mA interfaces can be connected to DP820.


Use DP820 with Module Termination Units TU810V1, TU812V1, TU814V1, TU830V1, TU833.
