The ICS TRIPLEX T8448 is a 24Vdc trusted zone interface module built with triple modular redundant (TMR) architecture, specifically designed for safety-critical industrial applications like fire and gas protection systems. Boasting 40 channels, it acts as a vital link between field devices and Triplex Trusted control systems, responsible for signal conditioning, data acquisition, and reliable data transmission. It supports a backplane supply of 20 – 32 Vdc and a field supply of 18 – 32 Vdc, with a maximum current of 2A per channel and 3A per power group. Operating within a temperature range of 0°C to 60°C and 10% – 95% non – condensing humidity, it features reinforced isolation between power groups and basic isolation between channels to resist interference. Compliant with safety standards suitable for critical industrial scenarios, this US – made module enables flexible system configuration and is widely applied in oil, gas, and chemical sectors to ensure fault – tolerant and stable operation of safety instrumented systems.
The characteristics of this module are mainly reflected in the following aspects:
Wide range of power supply voltage: This module can operate within the voltage range of 20 to 32V DC, and the on-site voltage range is also between 18 to 32V DC. In addition, it can withstand a maximum voltage of -1 to 40V DC, which allows it to operate stably in various industrial environments.
Strong fault tolerance in circuit design: This module adopts a fault-tolerant design with completely triple selectable circuits, that is, there are three identical circuits working simultaneously inside the module. This design can effectively ensure the correctness and reliability of the output, even if some circuits fail, other circuits can continue to work normally.
Multiple monitoring outputs: This module has 40 independent channels, each of which can be used for monitoring and output. This allows it to process multiple input and output signals simultaneously, improving work efficiency.
Flexible power pack allocation: The module is divided into 8 independent power packs, each with 5 working outputs. The design of this power pack makes the distribution of electricity more flexible, and the output of each power pack can be adjusted according to actual needs.
High rated output current: The rated output current of each channel of each power pack is 2A, and the total maximum output current is 8A. This makes the module perform well when driving high-power devices.
