Installing the Linear Positioning Module

The two discrete outputs for each loop are powered by the discrete output power

supply. The characteristics of the discrete outputs are:

Low no voltage applied to the output

High output supply voltage applied to output

Maximum Current 100 mA

Voltage Drop 1.6 VDC maximum (at 100 mA) between the dis

crete output power supply (terminal 40) and the

discrete outputs

Power for the OUTOUT 1 and OUTPUT 2 discrete outputs comes from the

discrete output power supply through terminal 40 on the module wiring arm.

The return for the load driven by OUTOUT 1 or OUTPUT 2 connects to the

common of the discrete output power supply.

Figure 5.12 shows a typical discrete output connection.

*The discrete outputs can be connected to inputs of other

modules provided that the current does not exceed 100mA.
