T1-55
Multichannel preset counter and frequency meter with 2 encoder inputs
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 multichannel preset counter and frequency indicator T1-55 can manage 8 independent preset
digital outputs related to the totalizing counters or the frequency values of pulses read through 8 digital
inputs and 2 encoder inputs; one of these can be a bi-directional encoder with a marker pulse that can
automatically reset the related up/down totalizing counter; also 2 analog outputs are available as an
option. The T1-55 is made of a base module that can be mounted on a DIN rail and a front mounting
operator panel that offers an effective and easy to use programming and supervision interface; special menu driven procedures allow confi guration of measuring units, preset values, counters reset modes and
operation logic. The good operation of the device is controlled by a watch-dog and indicated through
a “status-ready” output. The link with a supervisory center is provided by a serial RS422/485 interface
with a Modbus protocol.
| Digital inputs: |
• 8 Digital inputs, common positive (24 V) and can be used for reading pulses with frequency less than 500 Hz and 50% duty cycle |
| Digital outputs: |
• 8 Digital outputs, PNP type (24 V) with maximum current 100 mA |
| Encoder inputs: |
• 2 Encoder inputs, optically isolated and have a status indicator led; they accept both balanced (line driver) and unbalanced (open collector) signals with frequency up to 30 kHz. One of the two inputs can be connected to a bi-directional encoder with marker puls |
| Totalizing counter and frequency: | • For each digital input and encoder input a frequency measurement and a totali-zing counter are provided |
| Preset outputs: |
• The eight digital outputs are freely configurable as preset outputs |
| Communication interface: | • optically isolated RS422/485 serial communication interface with Modbus protocol; up to 31 devices can be connected to the same master supervision unit. |
| Scada software: |
• WINLOG-A is the real time software package reccomanded when a PC supervision of T1- 55 devices is required. WINLOG-A software provides an operator interface in a Windows environment for process supervision, recipes programming, analysis of historical trends, alarms management, and printing of reports. |
