Digital Output Interface

Chapter 7: Digital Output Interface

7.1 Overview

Sixteen general purpose digital output (DOUT) channels are

available on the 2426 module. DOUT channels are numbered 0

to 15.

Figure 10: DOUT Channel Block Diagram

As shown in Figure 10, every DOUT channel has a control

circuit that includes a state register, optical isolator, and

active-low, open-collector output transistor. The transistor

applies the common GND signal to -DOUT when the channel

is turned on.

Under software control, each DOUT channel may be

configured to operate in either Standard or PWM mode. In the

Standard mode (default upon module reset), a channel is

programmed to explicit, static states by the network client.

When operating in PWM mode, a channel will output pulses

having period and duty cycle specified by the network client.

Integral support is provided for system interlock circuits and

multiple DIO power supply voltages. Each DIO channel may

be powered from any power source available on the module’s

internal power bus (see “Internal Power Bus” on page 4).

DOUT 0-15 - Each of these will light when its affiliated

channel is programmed to the “on” state, independent of

the channel’s operating mode. Note that these reflect the

programmed states of DOUT channels; a channel’s

physical and programmed states may differ if:

• The channel is connected in a “wired-or” topology and

its programmed state is off, but an external driver on the

same channel is turned on.

• The channel’s programmed state is on, but it is powered

from an interlock contact that is open.

Upon module reset, all channels switch to the off state and

default to the Standard operating mode.

7.2 DOUT Connector

All DOUT loads are connected to the module through the

female DB-37 connector labeled DOUT in Figure 2.

7.2.1 Load Connections

A channel’s output is, in effect, a differential pair consisting of

+DOUT and -DOUT. Whenever possible, the load should be

connected across these two signals as shown in Figure 11.
