3.12 Relay Isolated Vac/Vdc Digital Output Module
Caution
You cannot install a relay isolated Vac/Vdc DO module in slot #1 of any
expansion housing.
Relay isolated Vac/Vdc DO modules provide a total of eight isolated
DOs to control signaling functions. The DOs do not have surge
protection (this is a customer-provided feature, if necessary).

Digital Outputs
(DO)
8
Each DO supports/includes:
 A pair of Normally Open (NO) relay
contacts capable of handling a
maximum operating load of 6A at 240
Vac or 5A at 30Vdc.
 Output relay provides 500 Vdc
electrical isolation for the DO.
 Maximum operating frequency of 360
operations per hour (under rated load).
 LED that turns ON when DO is ON.
Isolated Vac/Vdc DO modules consist of a DO PCB with two 10-point
terminal block assemblies (for local termination), one configuration
jumper, an LED daughterboard with eight status LEDs (one for each
point), and a module cover. The DO PCB connects with the backplane
using a 36-pin gold-plated card-edge connector.

Isolation
Relays electrically isolate the Vac/Vdc DO field circuitry from the
module’s bus interface circuitry. An onboard DO load register stores
output data. At power up the DO load register clears and sets all
outputs to “off.”
Configuration
The relay isolated Vac/Vdc DO module is available in a single
configuration (part number 396687-01-6).
Setting Jumpers
The Vac/Vdc DO module has one jumper which enables the DI status
LEDs. See Table 3-27.
