1. DESCRIPTION AND PARAMETERS
The IC-7702 module includes optionally 2 32bit counters with 5 inputs or 4 32bit counters
with 3 inputs for connection of pulse signals or signals from incremental position encoders.
Timers, conditionally switched counters or signal period measurement are other available
optional functions. Input signals can be bipolar, 24 V DC with the common plus or minus pole,
or 5 V DC with the common minus pole, the direct inputs with the fast response are designed for
24 V DC, 2 A with the common plus pole. The outputs are realized by semiconductor switches
equipped with overcurrent and thermal protection. These protection equipment is a part of
module diagnostics. The outputs can be used for the two-state drives control to set the position
of moving axes of machines, with the possibility of slow down points or with outputs in timer
functions. Values setting and observation is performed by user program.
The connector for input and output signal connecting with 20 terminals is delivered separately
(it is not included in the module delivery). The following variants can be use:
• screwless, with spring terminals TXN 102 30 (mounted in the axe of conductor)
• with screw terminals TXN 102 31 (the screw is in the axe of conductor)
• with screw terminals TXN 102 32 (the screw is at the right angle to the conductor)
The connectors are described in documentation TXV 102 30 or in the handbook for designing
TXV 001 08.01.
