The T1-55 is a module suited for DIN rail mounting that can be linked to a local operator panel (F1-10); it provides 2 encoder inputs for frequency up to 50 kHz and 8 digital inputs for frequency up to 0.5 kHz with 10 pulse counters and 10 frequency meters (one for each input); the counter associated with the first encoder input is up/down type with automatic reset on tag pulse; 8 preset alarm outputs are available and it is possible to programm measuring units, preset values, counters reset mode and operation logic; inputs and outputs are optically isolated and have a status led; 2 additionale analog outputs (0-10 V) can be provided as an option; an internal watch-dog circuit ensures a non-stop operation; a RS422/485 serial interface with Modbus (Ascii or Rtu) protocol is also available.
