3.4 Isolated Digital Output (DO) Module
Isolated DO modules provide 16 DOs to control signaling functions.
DO modules consist of a DO PCB with either two 10-point terminal
block assemblies (for local termination) or two 14-pin mass termination
headers (for remote termination). DO modules also include two
configuration jumpers, an LED board with 16 status LEDs (one for each
point), and a cover assembly. The DO PCB connects with the backplane
using a 36-pin gold-plated card-edge connector.

Configurations
The isolated Digital Output (DO) module (general part number
396572-XX-X) comes in two possible configurations, see Table 3-5:

daughterboard.
396572-04-9 remote Includes LED
daughterboard.
Isolation
Surge suppressors and optocouplers electrically isolate the DO field
circuitry MOSFETs from the module’s bus interface circuitry.
DO modules provide a total of 16 DOs with surge protection. Each DO
uses an open source MOSFET that is capable of driving up to 31Vdc at
up to 500mA. A 500Vdc MOV to chassis and a 31Vdc MOV (across
output) are provided to protect each DO. The maximum operating
frequency is 20 Hz.
Outputs set OFF on
Power-up
An on-board DO load register stores output data. At power-up the load
register clears and sets all outputs to “off.”
Setting Jumpers
DO modules contain two configuration jumpers (W1 and W2), which
