Dual 24Vdc Analogue Input
Module - 60 Channel
Introduction
The Trusted
TM
Dual 24V dc Analogue Input module interfaces to 60 field input devices. Comprehensive
diagnostic tests are performed on each input channel. Fault tolerance is achieved through the ‘One-
Out-Of-Two D’ (1-oo-2D) voting architecture within the module for each of the 60 input channels.
Using the built-in line-monitoring feature, the module can detect open and shorted field cables. Line
monitoring functions are independently configured for each input channel.
The module provides on-board Sequence of Events (SOE) reporting with a resolution of 1ms. A
change of state triggers an SOE entry. States are determined by voltage thresholds that can be
configured on a per channel basis. When the field voltage and field return are connected to the
auxiliary input channels of the module, thresholds can be specified as a ratio of the field supply voltage.
Features
• 60 dual input channels per module.
• Comprehensive, automatic diagnostics and self-test.
• Selectable line monitoring per channel to detect open circuit and short circuit field wiring
faults.
• 2500Vdc opto/galvanic isolation barrier.
• On-board Sequence of Events (SOE) reporting with 1ms resolution.
• Module can be hot-replaced on-line using dedicated Companion (adjacent) Slot or
SmartSlot (one spare slot for many modules) configurations.
• Front panel module status LEDs indicate module health and operational mode (Active,
Standby, Educated)
