Motion Coordinator MC224
24v Input Channels
The Motion Coordinator has 16 24v Input channels built into the master unit.
These may be expanded to 256 Inputs by the addition of CAN-16 I/O modules.
All of the 24v input channels have the same circuit although 8 on the master unit
have 24v Output channels connected to the same pin. These bi-directional chan-
nels may be used for Input or Output to suit the application. If the channel is to
be used as an Input the output should not be switched on in the program.
24v I/O Channels
Input/output channels 8..15 are bi-directional. The inputs have a protected 24v
sourcing output connected to the same pin. If the output is unused it may be
used as an input in the program. The input circuitry is the same as on the dedi-
cated inputs. The output circuit has electronic over-current protection and ther-
mal protection which shuts the output down when the current exceeds 250mA.
Care should be taken to ensure that the 250mA limit for the output circuit is not
exceeded, and that the total load for the group of 8 outputs does not exceed 1
amp.
