3.13 Isolated Digital Input/Output (DI/O) Module
Isolated Digital I/O modules provide four isolated DOs that are
externally powered and twelve isolated DIs.

Characteristics
Isolated Digital
Outputs (DO)
4
Each isolated DO supports/includes:
 Externally powered. Supports 500mA
maximum load (nominally powered
from a 10Vdc supply [30Vdc max]_
 Surge protection.
 Open source MOSFET drives up to
31Vdc at up to 500mA.
 500Vdc MOV to chassis and 31Vdc
MOV (across output) protect each DO.
 Maximum operating frequency of 20
Hz.
Isolated Digital
Inputs (DI)
12
Each isolated DI supports/includes:
 Jumper allows externally powered
single end inputs or internally sourced
dry contact operation.
 Nominal input voltage of 24Vdc.
 Nominal input current of 5mA.
 30 ms filtering.
Isolated DI/O modules consist of a DI/O PCB with two 10-point
terminal block assemblies (for local termination), 14 configuration
jumpers, an LED daughterboard with 16 status LEDs (one for each
point), and a module cover. The isolated DI/O PCB connects with the
backplane using a 36-pin gold-plated card-edge connector.

Configuration
The isolated DI/O module is available in a single configuration (part
number 396804-01-2).
Isolation
Surge suppressors and optocouplers electrically isolate the DI field
circuitry from the module’s bus interface circuitry.
When configured for use in dry contact applications, all DIs use a built-
in +21Vdc field power supply. This is an isolated supply powered by
the output of the +VIN power source originating on the PSSM. Use
jumper W15 to enable or disable the +21Vdc field power supply.
