Digital inputs/outputs

24 V DC, dedicated inputs/outputs can be used for specific counting functions:

- Catch/touch operation, counter value stored in separate variable on external event (rising or falling edge)

- Set input to preset counter register with predefined value

- Set input to reset counter register

- End value output; the output is set when predefined value is reached

- Reference point initialization (RPI) input for incremental encoder initialization

All unused inputs/outputs can be used with the specification of standard input/output range.

Effect of incorrect input terminal connection: Wrong or no signal detected, no damage up to 35 V.

Fast counter/encoder

integrated, 2 counters (hardware interface with +24 V DC, +5 V DC, differential and 1 Vpp sinus input) with up to 12 configurable operation modes:

- 32 bits one counter mode

- 16 bits two counter mode

- Incremental position encoder

- Absolute SSI encoder

- Time frequency meter

- Frequency input up to 300 kHz

PWM/pulse outputs

2 pulse-width-modulators or pulse outputs

Output specification
