Maxiflex 8AI Module Model M1434
GENERAL DESCRIPTION
The M1434 8AI ISO 8 channel
analogue input module provides 8
voltage inputs (1-5V).
Current inputs can be accomodated
using an external 250 ohm shunt
resistor switched in across the input.
The module may be inserted into any
I/O slot in a Maxiflex system.
Features

Inputs are terminated on plug-in screw
terminals. The module can be inserted or
removed while the system is powered.
Auto-detection capability allows
Maxiflex CPU to recognise the presence
of this module in the system.
Module configuration is retained in the
Maxiflex CPU. When a module
replaced, the CPU will download the
correct configuration to the new module
automatically.
