DC302- Operation and Maintenance Instruction Manual
5.2
DC302 Open Collector Outputs
Description
– Outputs
The outputs are designed with open collector NPN transistors that are able to drive relays,
solenoids and other DC loads with up to 0.5 A per output. All channels within a group share the
same ground whereas groups are isolated from each other and the Fieldbus network.
In case of failuring of output power supply there will be an indication in the BLOCK_ERR
parameter for output function blocks such as DO, MDO, FFB, STEP_PID (See Function Blocks
Manual).
NOTE
The discrete outputs can be used by several blocks, such as DO, MDO, STEP_PID, FFB.
However, an output or group that is being used with one block, can not be used by another block.
