Description:
16809-41/5 QLCDM024DCBAN is a Critical Discrete Module,manufactured by Siemens.
The Critical Discrete Module (CDM) interfaces discrete DC sensors and actuators with a control module’s IOBUS. It provides 32 channels. Each channel can be configured as any of the five discrete channel types: an input, an output, an event recording input, an event recording output, or a pulse output.
The CDM’s inputs are current sinking (i.e. the input device is wired between the power supply positive and the I/O terminal). Outputs are current sourced (i.e. the output device is wired between the output terminal and power supply common). In addition, a soft-fuse circuit protects each output channel from a short-circuit in the field wiring and prevents a short from affecting other CDM channels. Note that a soft-fuse can be reset locally or remotely.
All channel types, except pulse output, can be configured to run pulse test diagnostics to ensure the channel is in working order. The diagnostics require inputs to have an external device called a Safety-Related Switch Adapter (SRSA). The diagnostics detect shorts in the field, channel-to-channel shorts, and channel-to-power shorts.
