Delta RMC151 - Manual (Page 689)

7 Hardware
Analog Input Features
• Two 16-bit analog inputs, ±10 V or 4-20 mA
Discrete I/O Features
• 6 I/O, individually configurable as input or output
• Inputs: 12 to 24 VDC, sinking (require sourcing driver)
• Outputs: Solid state relay, 50 mA continuous
• Inputs 0 and 1 can be used as high-speed registration inputs in conjunction with the
quadrature inputs.
High-Speed Channels
Each of the two RS-422 channels are independently configurable as Quadrature or SSI.
Quadrature Channels
• A and B quadrature inputs
• Requires 5 V differential (RS-422) signals
• Discrete inputs 0 and 1 can be used as high-speed registration or homing inputs in
conjunction with quadrature inputs 0 and 1, respectively.
SSI Channels
The SSI channels can be configured to do the following tasks:
• Receive SSI Input from a Transducer
This is a standard SSI input for obtaining data from an SSI transducer or encoder.
• Monitor SSI Communication on Another Device
The SSI channel can monitor the data that another RMC is receiving from an SSI
device. This makes it possible to synchronize multiple RMCs to one SSI transducer.
• Send Data Out Via SSI (Slave)
The SSI channel behaves as a transducer or encoder and will return data to the
requesting master.
• Send Data between RMCs
The SSI channels can continuously send any RMC register to an SSI input on another
RMC. This provides communication between RMCs. Notice that only one register can
be transferred between RMCs.
Part Number
The UI/O Module can be placed in slot 0, 2, 3, 4, or 5 of the RMC150 backplane.
However, because the backplane connector of slot 0 (the leftmost slot) is different from
that of slots 2-5, the part number of a UI/O module for slot 0 differs from a UI/O module
for slots 2-5.
If placed in slot 0, the part number is UI/O. If placed in slots 2, 3, 4, or 5, the part
number is Un, where n is the number of U modules. Multiple Universal I/O modules can
be placed in the same rack.
Slot Part Number
0 UI/O
This must be added to the end of the part
number, for example RMC150E-M1-H2-UI/O.
2-5 Un
where n is the number of UI/O modules, for
example RMC150E-M1-U2.
Setting Up UI/O Analog Inputs
1. Wire the analog input as described in the Analog Wiring topic.
