3.3 Isolated Digital Input (DI) Module
Isolated DI modules provide 16 isolated digital inputs. For 24V DI
modules you can individually configure inputs for either externally
sourced inputs or internally powered (dry contact) applications.

Characteristics
Digital Inputs (DI)
16
Each DI supports/ includes:
 Nominal input voltage of 12V or 24Vdc
 Nominal input current of 5 mA
 30 ms input filtering
 Dedicated LED on module turns ON
when DI is ON. (not available on all
module versions)
A DI module consists of an isolated digital input printed circuit board
(PCB) with either two 10-point terminal block assemblies (for local
termination) or two 14-pin mass termination headers (for remote
termination). Each DI module also includes 19 configuration jumpers
and a module cover. The DI PCB connects to the backplane using a 36-
pin gold-plated card-edge connector.

Configurations
Isolated Digital Input (DI) modules (general part number 396571-XX-
X) come in different configurations. See Table 3-2 to see the
variations.

Part Number Termination Connector Notes
396571-02-6 24V local Includes LED
daughterboard.
396571-04-2: 24V remote Includes LED
daughterboard.

Figure 3-3, Figure 3-4, and Figure 3-5 show wiring for the DI module.
Isolation
Surge suppressors and optocouplers electrically isolate the DI field
circuitry from the module’s bus interface circuitry. 24V input modules
configured for use in dry contact applications contain a +21 Vdc
isolated power supply powered by the output of the +VIN power
