ICS Triplex |T8448|Trusted TMR 24Vdc Zone Interface Module
Description
The Trusted TMR 24Vdc Zone Interface Module (T8448) is designed for use in Fire and Gas protection systems. It interfaces with up to 40 field device inputs or actuators, providing all necessary connections to protect one or more zones. The module supports a variety of signal types and integrates reset signals for latching detectors without additional hardware. It's separated into 5 power groups of 8 channels each, allowing flexible configuration for different zones. Data from this module feeds into the Trusted TMR System for logic solving. Note that this module is not approved for direct connection to hazardous areas and should be used with Intrinsic Safety Barrier devices.
Features
- 40 TMR selectable I/O points.
- Interfaces with 4-20 mA gas detectors, fire, heat detectors, break glass units.
- Up to 5 programmable field device reset signals.
- Supports two or three-wire field devices.
- Fuse protection on inputs.
Technical Specifications
- Channels: 40 individual configurable as Analog Input, Digital Input, or Digital Output.
- Power Groups: 5 groups, each with 8 channels, combinable for zone-specific configurations.
-
Signal Types:
- Analog Inputs: 4-20 mA
- Digital Inputs/Outputs: Boolean
-
Thresholds:
- LOW falling/rising
- HIGH falling/rising
- HIGH-HIGH falling/rising
- Short Circuit Protection: Template required for detection while outputs are de-energized.
-
Accuracy:
- Voltage measurement: ±0.5% of reading + 1 count
- Current measurement: ±0.5% of reading + 1 count
- Operating Temperature: -40°C to +70°C
- Relative Humidity: 5% to 95%, non-condensing
-
Weight & Dimensions:
- Weight: 1.36 kg (3 lbs)
- Dimensions: 216 mm x 127 mm x 102 mm (8.5 in x 5 in x 4 in)
-
Fault Detection:
- Triplicated diagnostic tests for current and voltage.
- Stuck-on and stuck-off failure detection.
- All inputs treated as analog and fully tested.
-
Sequence of Events (SOE):
- Automatic logging of time-stamped state changes for input/output and line fault status variables.
- SOE data retrievable via SOE and Process Historian Package on the Engineering Workstation.
-
System.INI File Configuration:
- Customizable operating characteristics for the module and individual channels.
- Short circuit detection template for de-energized output states.
- Default settings available; customization only needed if defaults are unsuitable.
