Description:
Encoder board for VACON
®
NXP. Encoder input board with programmable
control voltage for an encoder.
The encoder board OPTA4 is for TTL type encoders (TTL, TTL(R)) providing
input signal levels that meet the RS_422 interface standard. Encoder inputs
A, B and Z are not galvanically isolated. The OPTA4 board includes, too, the
qualifier input ENC1Q (meant to trace the Z-pulse in certain situations) and a
special/fast digital input DIC4 (used to trace very short pulses). These two
inputs are used in special applications.
The TTL type encoders do not have an internal regulator and use therefore a
supply voltage of +5V±5% whereas the TTL(R) type encoders have an internal
regulator and the supply voltage can be e.g. +15V±10% (depending on the
encoder manufacturer).
Allowed slots: C
Type ID: 16692
Terminals: One terminal block; Screw terminals (M2.6); Coding in terminal #3.
Jumpers: 2; X4 and X2 (see page 25)
Board parameters: Yes (see page 27)
