The analog output module is equipped with 4 independent analog
outputs. The output voltage range, resolved with 8 bits, is 0-10V,
but can be reprogrammed within 0-10V via software (e.g. 1-10V for
connecting standardised ECGs). The voltage outputs are galvani-
cally separated from the subnet and from the operating voltage of
the module. There is no potential separation between the 4 outputs.
Function displays
• 1 red LED indicates the operating voltage
• 1 yellow LED flashes to indicate communication with the master via the subnet
• 1 green LED indicates the regulation of the outputs (LED flashes until the desired final value is reached)
The following functions can be performed independently by the DA module:
• Calculation of rise times from 0.5 seconds to 12 hours
• Autonomous running from current analog ACTUAL values to preset analog SETPOINT values at a preset speed (optionally in a preset time)
• Feedback „Analog value reached“ after execution of time functions
• Stop function during the execution of time functions
• OVERSAMPLING error correction (With the so-called „OVERSAMPLING“, the DA module automatically corrects the jumps in the analog
values caused by the cycle times of the BUS system. For this purpose, the analog values between the BUS cycles are transformed back
into the resolution of 8 bits by linearisation. This prevents, for example, flickering when controlling dimmers. During programming the OVER-
SAMPLING is called SOFT function.)
• Execution of blinking functions
• Adaptation to different light sources and dimmers
• Calculation of defined and definable curves
• Calculate minimum and maximum settings per channel to use full 8 bit width
• Complex emergency operation function
Inputs / Outputs
• 4 analog outputs 0(1)-10V
• 1 emergency operating input „E”. The function can be parameterised per channel.
Connections
• 1 connection for the subnet (BUS A and B, RS-485)
• 1 connection for the operating voltage (Ub, 0V)
• 4 outputs 0-10V (1-10V)
• 4 GND connections for outputs (internally connected)
• 1 emergency operating connection
• 2 P-COM connections (subnet and operating voltage)
The outputs can be loaded as current source or current sink with
20mA per output. 0-10V and 1-10V control is easily possible with
this module. The module can also be set from speed calculation to
absolute time calculation by parameterisation per channel. With this,
all conceivable control tasks from individual light dimming to use for
complex lighting scenarios can be easily realised.
