2.4.2 Connections
(2) 24-pin screw terminal for connecting the input signals
(3) 3-pin screw terminal for connecting the power supply
(4) 3-pin screw terminal for connecting the communication
2.4.3 Controls
(5) 2-pin plug connector to activate a terminating impedance for the RS-485 interface.
Normally, the communication on the RS-485 network should be trouble-free with-
out activation of the terminating impedance (jumper not plugged in), because the
data rate is comparatively low.
(6) 2-pin plug connector (one per input) to select the input signal (relay contact or volt-
age input).
For use as a relay contact, the jumper must be plugged in (factory setting).
For use as a voltage input, the jumper must not be plugged in.
(7) 4-way DIL switch, currently without function.
2.4.4 LEDs
(8) Transmit LED TxD (red)
(9) Receive LED RxD (red)
(10) Input LEDs (red) - one per input
(11) Status LED (yellow)
(12) 12 V LED (green) - power for external relay contacts
(13) Operating voltage LED (green)
2.5 Connection of the power supply
The power supply (230 VAC) has to be a permanent installation. The wires for the power
supply are to be connected to the screw terminals marked with PE, N and L.
