Device Description

The I/O module 750-677/040-000 (4PWM 24 VDC 0.2A XTR) outputs adjustable
PWM signals at four channels separately.
The channels can be configured individually in such a way that they work like
low-side switches or high-side switches, but are each designed as a half bridge
("push-pull").
If a channel pair is not enabled, the output is high-resistance (Tri-state).
The channels are enabled via bit 0 of the control byte ("Enable device drivers
DO1 & DO2" or "Enable device drivers DO3 & DO4").
The channels are designed to be short-circuit protected
The I/O module 750-677/040-000 supports five operating modes. The "PWM DC"
operating mode is set by default. In both "PWM DC" and "PWM Frq" operating
modes, all four channels may be used independently.
It is also possible to switch channels "DO1 & DO2" as well as "DO3 & DO4" in
parallel.
In the other complex operating modes ("PWM Frq-Cnt", "Pulse Frq-Cnt" and
"PWM Pulse-Dir"), two channels functionally correlate with each other.
The first channel outputs the PWM signal and the second channel a static signal
("0" or "1").
Please refer to the Section "Operating Modes" for setting options and the bit
signification in the process image.
The assignment of the connections is described in the "Connectors" section.
The meaning of the LEDs is described in the "Display Elements" section.
The I/O module 750-677/040-000 (4PWM 24 VDC 0.2A XTR) receives the 24 V
voltage supply for the field level from an upstream I/O module or from the
fieldbus coupler/controller via blade-formed power jumper contacts. It then
provides these potentials to subsequent I/O modules via spring-formed power
jumper contacts.
Do not exceed maximum values via power contacts!
The maximum current that can flow through the power jumper contacts is 10 A.
The power jumper contacts can be damaged and the permissible operating
temperature can be exceeded by higher current values.
When configuring the system, do not exceed the permissible maximum current
value. If there is a higher power requirement, you must use an additional supply
module to provide the field voltage.
With consideration of the power jumper contacts, the individual modules can be
arranged in any combination when configuring the fieldbus node.
An arrangement in groups within the group of potentials is not necessary.
