Figure 5.22 198-OW2S-Q5 Series A DeviceNet Valve Module
The DeviceNet Valve module 198-OW2S-Q5 is designed to provide two output contacts to
operate up to two 24V DC pneumatic valves. The +24V DC supplied by the module is
sourced from the DeviceNet power supply. The +24V DC supply is isolated from the
DeviceNet power via a DC-to-DC converter. Since the DeviceNet power supply may vary
between 25…110V, only outputs that are rated for this range of operation should be attached
to the port. The 198-DN and 198-DNG modules support a voltage warning bit, which will
activate if the voltage on the DeviceNet bus falls below 18V. The output status of the valve is
not guaranteed below this point, and system designers should use this information
accordingly.
Assembly Instances 104 and 105 are default for 198-DNG. Assembly Instances 106 and 107
are default for 198-DN.
