The button pulses (buttons 1-3) cause an incremental change to analog output
AOUT.
A lit button provides visual feedback.
When a lit button is connected, optical feedback (flashing) is generated when it is activated.
AOUT: Starting voltage 4V control range 4 / 5 / 6 / 7 / 8 / 9 / 10V
Dout4: ON when AOUT is active / ON when AOUT 0V and non-active (enable)
Air valve control:
If AOUT is active, a pulse combination to S2 (2 pulses within 0.5sec) causes digital output
DOUT2 to be activated.
DOUT2 can be set to inactive again with
a)
S3 - System OFF
b)
Pulse combination to S2 (2 pulses within 0.5sec)
Switching output of Dout2: 24V DC Imax = 20mA DC
To be able to switch an air valve with a higher electrical output, a multi-function relay item
no. 55323 can be connected to DOUT2.
