Pin Wire Color Signal Name Signal Level Remarks
3 Green Ground —
GND Ground Reference potential
4 Yellow Digital input —
Input Input (low active):
On: 0-0.4 V
Off: 2.2-5 V
Pull-up resistor: 47 kΩ to 5 V Digital input; reference potential is
ground. Note the following:
• The maximum input voltage at the
input must not 5 V with
reference to ground.
• The minimum input voltage must
not be lower than the ground
potential.
5 White Relay output
— Relay_COM Potential free Common contact for NO and NC
6 Brown Relay output
— Relay_NO Potential free
0-24 V, 0-100 mA Closing contact
Prerequisites
To use the digital I/O functionality, the following prerequisites must be
fulfilled:
• The digital I/O port must be connected to the external device with
the digital I/O signaling cable (part no. 6036.0006).
• The inputs and outputs that you want to use must be selected in the
Instrument Configuration Manager.
Connecting a Digital I/O Port
1. Plug the 6-pin connector of the cable into the digital I/O port that
you want to use.
2. For each relay output or digital input to be used, connect the
appropriate signal wire and ground wire to the corresponding
connectors on the external device. For details, refer to the
documentation provided with the external device.
Selecting the inputs and outputs in the Chromeleon software
1. In the dialog box for the pump, on the Inputs and Outputs pages,
select the inputs ( Pump_Input_X ) and outputs ( Pump_Relay_X ) that
you want to use. The numbering in the dialog box corresponds to
the port numbers on the pump.
2. To configure the bidirectional input/output ( Pump_IO_X ), select the
related check box on either the Inputs or Outputs page, depending
on the preferred usage.
