40 Channel ICS T8448 Trusted TMR 24Vdc Zone Interface Module

ICS T8448 Trusted TMR 24Vdc Zone Interface Module 40 Channel

ICSTT-RM278P-EN-P (PD-T8448)

Product Overview:

The Trusted® TMR Zone Interface Module has been designed to provide a configurable interface specifically for use in Fire and Gas protection systems. The Module interfaces to up to 40 Fire and Gas field device inputs or actuators. Each of the 40 I/O Channels can be individually configured as Analogue Input, Digital Input or Digital Output to provide all of the interfaces needed to protect one or more Fire and Gas Zones. Interfacing to the field devices is through a Versatile Field Termination Assembly type 8842, which provides the field loop conditioning for each of the types of signal, and enables the connection of reset signals for latching type detectors without the need for external hardware. The Module is separated into 5 power groups each with 8 channels. Power groups can be combined together to provide a configurable number of channels for each Fire/Gas Zone. All of these functions provide data to the Trusted TMR System which acts as the logic solver. This Module is not approved for direct connection to hazardous areas and should be used in conjunction with Intrinsic Safety Barrier devices.

Triplicated diagnostic tests are performed throughout the Module, including measurements for current and voltage on each portion of voted input or output channels. Tests are also performed for stuck on and stuck off failures. All inputs are treated as analogue and are fully tested. Fault tolerance is achieved through a Triple Modular Redundant (TMR) architecture within the Module for each of the 40 channels

Features:

• 40 Triple Modular Redundant selectable input/output points per Module. • Inputs interface to 4-20 mA gas detectors, Fire and Heat detectors, Break Glass units etc.

• Programmable Field Device Reset signals (up to 5 individual resets).

• Two or Three Wire Field devices through 8842.

• Fuse Protection of Inputs and Outputs through 8842, external to the Module.

• High Power Digital Outputs to interface to Dampers, Extinguishant Release, Fire pumps etc.

• 5 Isolated Power Groups to allow flexible and efficient field configurations

• Comprehensive automatic diagnostics and self-test.

• Automatic line monitoring per point to detect faults in field wiring and loads.

• 2500 V impulse withstand opto/galvanic isolation barrier.

• Automatic over-current protection (per channel), no external fuses required.

• On-board Sequence of Events (SOE) reporting with 1 ms resolution.

• Module can be hot-replaced on-line using dedicated Companion (adjacent) Slot or SmartSlot (one spare slot for many Modules) configurations.

• Front Panel output status Light Emitting Diodes (LEDs) for each channel indicate 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.
