D300529 0115 - BL67 I/O modules
12-63
BL67-1CNT/ENC
12.5 BL67-1CNT/ENC
The BL67-1CNT/ENC allows the connection of encoders as well as signal- and direction inputs, whereas
the output of the direction is optional.
The module provides a 24 VDC power supply of connected encoders.
The counter can be used as input module for RS422-outputs as well as digital input with a parameter-
izable threshold for push-pull-outputs (single ended) (0 to 30 V) (see parameter Encoder signal).
RS422-input:
– signal evaluation between A, B, Z and /A, /B, /Z
– power supply of 5 V-encoders has to be realized externally
push-pull-input (single ended)
(digital input with parameterizable threshold):
– signal evaluation between A, B, Z and GND.
The inputs /A, /B and /Z are internally connected to GND.
– push-pull-inputs (0 to 30 V)
– threshold freely parameterization (1 to 18 VDC)
Additionally, the module provides 4 digital outputs and 4 digital inputs, whereas the channels DI0 and
DO0 and DI1 and DO1 respectively are connected to the same contact (DIO0 and DIO1).
The digital inputs can be used as counter release.
