PCD2.W600

The voltage input signals are connected directly to the 10-pole terminal block (E0 … E7 and COM). To minimize the amount of
interference coupled into the module via the transmission lines, connection should be made according to the principle explained below.

This module can interact with the watchdog, if it is used on base address 240. For details, please refer to the manual “27-600_I/O-modules for PCD1 / PCD2 series and for PCD3” in chapter “A4 Hardware Watchdog”, which describes the correct use of the watchdog together with PCD components.

I/O modules and I/O terminal blocks may only be plugged in and removed when the Saia PCD® and the external +24 V are disconnected from the power supply.
