Fitting and Installation
2.5.7. Analogue output 2
The analogue output is not electrically isolated. The minus is at ground
potential.
Terminal 15 + current output 2
Terminal 16 - current output 2
Umax = 24 V
I = 4 - 20 mA
2.5.8. Digital inputs
The CTR 210 has six digital inputs.
The digital inputs are active. Passive switches or optical couplers can be
connected.
Terminal 19 + digital input 1
Terminal 20 + digital input 2
Terminal 21 + digital input 3
Terminal 22 + digital input 4
Terminal 23 + digital input 5
Terminal 24 + digital input 6
Terminal 25 GND digital inputs
Umax = 5,3 V
Imax = 0,2 mA
The inputs can be connect with up to 30 VDC active. Please note that the off
state is registered only if the plus input is switched to 0V. To open the contact is
not enough.
