D300529 0115 - BL67 I/O modules
7-3
Overview
7.1 Overview
Digital output modules (DO) receive output values from the gateway via the internal module bus. The
modules convert these values and transmit the corresponding high or low level signals for each chan-
nel to the field level via the base modules.
The outputs are rated accordin
g to EN 61131-2 type 2.
The sensor supply (V
O
) is tapped from the internal voltage supply bus.
The sensor voltage V
sens
is supplied by the gateway or a Power Feeding module.
The module bus electronics of the digital output module
s are galvanically isolated from the field level
via an opto-coupler.
WARNING!
WARNING!
LED displays
Channel statuses are indicated by LEDs. Error signals fr
om 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.
Automatic recovery of outputs
Active outputs
Deactivate the automatic recovery of outputs via the respective parameterization
Faulty safety-related switching-off
Active outputs
Switch-off digital outputs all-pole in galvanically isolated groups
ATTENTION!
High voltage when switching
-off inductive loads
Destruction of the electronic in the module
Provide an external suppressor.
