6.4 Terminal assignment for input/output signals
The following signals can be configured for external sampler control:
Input signals
• 2 analog signals 0/4 to 20 mA
• 2 binary signals > 100 ms pulse width or edge
• Signals of digital sensors with Memosens protocol (optional)
Output signals
• 2 Binary signals > 1 s pulse width or edge
The controller must be opened to allow the signal cable, sensor cable and optional relay to be
connected.
