3.1.6 OPTA7
Description:
Duplicate encoder board for VACON
®
NXP. Encoder input board with
programmable control voltage for the encoder.
The OPTA7 board is designed for HTL (High voltage Transistor Logic) type
encoders (voltage output type push-pull HTL, open collector output type HTL)
which provide input signal levels dependent on the supply voltage of the
encoder. The encoder inputs A, B and Z are galvanically isolated. The OPTA7
board includes, too, the qualifier inputs ENC1Q and ENC2Q meant to trace
positions in positioning applications.
The board can be used as both Master and Slave device. The encoder input
signal is repeated on the board and carried to the next device through the
digital output.
Allowed slots: C
Type ID: 16695
Terminals: Two terminal blocks; Screw terminals (M2.6); Coding in terminals #3 and
#14.
Jumpers: 4; X4, X5, X15 and X16 (see page 35)
Board parameters: Yes, see page 38.
