P20: Fast counters
multimodeproduct information
Your Content Goes Here- Use of a 10 Mhz DSP microprocessor.
- Possibility to generate an interrupt towards the CPU, selectable through jumpers among 3 different IRQs.
- Possibility to generate a periodic interrupt (with period from 20 ms ... 1.3 s) selectable through jumpers among 3 different IRQs.
- Simultaneous management of 8 fast counters:
- Freq.max reading Encoder Increm. = 60 KHz (15×4)
- Freq.max counts UP, UP/DOWN = 30 KHz
- Acquisition of incremental optical encoders (12...30 Vdc).
- Position range: ± 231 counts (32 bits).
- Management of 16 opto-isolated PNP digital inputs (12..30 Vdc).
- Management of 16 opto-isolated PNP digital outputs (12...30 Vdc); each output can supply up to 400 mA (current source).
- Coexistence of 8 P20 cards (addressable by jumpers), for a total of 64 simultaneous fast counters.
- EUROCARD format 100 x 160 mm.
- Front Panel: 4 TE.
- 1 DIN 96-pole male connector.
- 1 D-SUB 37-pole female connector.
(for connection to analogue inputs).
- Consumption:
- 650 mA on + 5 Vdc (from IPC Bus).
- 30 mA on +12 Vdc (from IPC Bus).
- 10 mA on -12 Vdc (from IPC Bus).
- xx A on +24 Vdc (field power supply).
- Input absorption: 12 mA at 24 Vdc.
- Field alim.range: 15..30 Vdc.
- Programming of the functioning mode of each single fast counting channel.
- Tsample programming (from 20 µs to 2 ms).
- Preset and/or read the values of each counter.
- Programming of the type of each input signal (Normal Open or Normal Closed).
- Internal board diagnostics (alarm detection).
- Programming and management of ACTIONS associated with EVENTS (reaction times: 50 µs...2 ms) (see tables below)
- Management of electric cams through the execution of actions on the front of programmable EVENTS.
- Coincidence of a counter with a programmed value.
- Positive or negative edge of an input signal.
- Set/Clear an output signal (electric cam).
- Sends an Interrupt to the supervisory CPU.
- Start/Stop of a counter.
