Output Power-I/O Connections

The

Continuum

NetController module includes a connector on the upper right side of

the case for further distribution of the 24 VDC input power and special I/O

communications signals. Continuum I/O modules use these signals for power and

communications as well.

The power-I/O connector is a five-pin male assembly that is designed to easily insert

directly into the left side (input) connector of any I/O module. The signals within that

connector are as follows:

PIN Function

5 +24 VDC

4 24 VDC Return

3 Ground

2 Comm B

1 Comm A

The power supply generates a +24 VDC source for all modules in the system. This

power source is received through the input power connector on the left side of the

CPU module and sent through to pins 4 and 5 of this connector. Pin 3 (Ground) is

intended as a signal ground connection.

Communications between the CPU and I/O modules is through a two signal serial

interface that can be internally configured as either RS 485 or Echelon LON FTT-10.

Pins 1 and 2 (Comm B and Comm A) provide the electrical connection for this

interface.
