Module Type Description Additional info
AI-100 Analogue input
Module
8 Analogue inputs, each can be set to one of the
following ranges: 30V, 15V, 5V, 1V, 0-30V, 0-15V,
0-5V, 0-1V, 20mA, 0-20mA, 4-20mA.
DI-300 Digital Input 8 discrete input channels. These inputs are sinking
inputs for 24VDC.
DI-301 Digital Input 16 discrete input channels. These inputs are sinking
inputs for 24VDC.
DI-330 Digital Input 8 discrete input channels. Universal inputs work
with any voltage from 5V TTL up to 250VDC/VAC.
Compatible with sourcing, sinking, or power
sensing applications.
DO-400 Digital output 8 discrete output channels. Max. 2A for each output,
max 8A for each module. Maximum voltage
30VDC.
DO-401 Digital output 16 discrete output channels. Max. 2A for each
output, max 8A for each module. Maximum voltage
30VDC.
For each I/O module, one Terminal Base is required - TB-1
Figure 36: National Instruments rail connected to DECT Messenger on page 112 shows how
one rail with National Instruments I/O modules is connected to DECT Messenger. On this rail
there can be various types of I/O Modules. The maximum number of modules for each rail is
eight. The modules shown in
Figure 36: National Instruments rail connected to DECT
Messenger on page 112 are examples only.

Note:
The maximum number of contacts for each eIO Module in DECT Messenger is 128.
Figure 37: National Instruments Modules connected to DECT Messenger on page 113 shows
a configuration of three rails with National Instruments modules connected to a DECT
Messenger. The three rails with modules are connected together through the RS-485 bus.
