Chapter 1
Product overview
The Trusted® TMR 24 Vdc Analog Input module interfaces to 40 sourcing field
input devices, acting as a current sink for all these devices. Comprehensive
diagnostic tests are performed on each input channel. Fault tolerance is
achieved through a Triple Modular Redundant (TMR) architecture within the
Module for each of the 40 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 onboard Sequence of Events (SOE) reporting with a
resolution of 1 ms. 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
•40 Triple Modular Redundant (TMR) 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.
•2500V impulse withstand opto/galvanic isolation barrier.
•Onboard Sequence of Events (SOE) reporting with 1 ms resolution.
•Module can be hot-replaced online using dedicated Companion
(adjacent) Slot or SmartSlot (one spare slot for many modules)
configurations.
•Front panel input status Light Emitting Diodes (LEDs) for each
channel indicate input status and field wiring faults.
•Front panel module status LEDs indicate module health and
operational mode (Active, Standby, Educated).
•TϋV Certified IEC 61508 SIL 3.
