Bachmann EII102 Counter / Time Measurement / Incremental Encoder Interface Module

Incremental encoder and counter evaluations at the

highest signal input frequencies are managed in automa

tion tasks by modules of the EII100 series. The digital

sensor signals to be acquired are configurable, thus ena

bling the connection of a wide range of sensors.

The module allows the counting of pulse edges as well

as the measurement of period and pulse duration. The

module offers the evaluation of incremental encoders up

to 32 MHz for demanding motion and handling applica

tions. Immediate reactions such as latch, reset or counter

enable are triggerable via digital inputs on the module. If

the actual position is reaching a configured comparison

value, module-to-module communication enables a digital

output to be switched at the adjacent module without any

time loss. Thus function initiate a machine response. Inte

grated sensor power supply units for 5 V and 24 V directly

in the terminal panel simplify wiring.

Features

● Up to 2 incremental encoder interfaces:– A, B, Z + inverted– 1-wire connection:

TTL, HTL– Differential transmission: RS-422. HTL– Calculation of the speed at the module

● Up to 6 channels as counters / for time measurement

● 6 DI for latch / homing / counter enable

● 2x 5 V DC / 24 V DC / GND encoder supply

● Oversampling

● Synchronous clocks

● Direct module-to-module communication:– Switching of DO at the adjacent module when the

target position / the comparison value is reached
