Digital Signal
Inputs
The parasitic capacitance of the lead connected to the digital inputs may not exceed 2.2μF as
a result of the ETAMATIC self-tests. The lead length should be limited to 100 m. Since the dig-
ital inputs are for 24V DC, suitable contacts for that voltage should be used (hard silver or gold-
plated)
Regular Firing Rate
Input
• via internal burner-firing-rate controller actual value
• manual operating is possible via three-point.step signal
• external burner-firing-rate controller (0/4 ... 20 mV)
Feedback Inputs Potentiometer 5k or current signal 0/4 … 20 mA (ETAMATIC S channel 1)
Optional: Direct switching of NAMUR transmitter (ETAMATIC S)
Control Outputs 4
