Digital combi modules
D300529 0115 - BL67 I/O modules9-2
9.1 Overview
The digital combi modules provide optically isolated in- and outputs according to IEC 6113, type 1.
The inputs detect electrical high- and low-level val
ues through the base module connections and trans-
mit the corresponding digital value to the gateway a
nd the outputs receive output values from the
gateway via the internal module bus. The modules convert these values and transmit the correspond-
ing high or low level signals for each channel to the field level via the base modules.
The sensor supply (V
sens
) and the output supply (V
O
) are tapped from the internal voltage supply bus.
They are short circuit proof (100 mA) and supplied be the module.
Short-circuit detection is realized in the module.
WARNING!
WARNING!
LED displays
Channel statuses are indicated by LEDs. Error signals fro
m the I/O level are indicated by each module
via the "D" LED. The corresponding diagnostic information is transmitted to the gateway via diagnostic
bits.
