1. Input Configuration 

Backplane Communication Interface: The module receives executive logic commands from the Tricon main processor via the TriBus triple-redundant backplane bus.

TMR Voting Logic Input: Three fully independent redundant circuit lanes separately receive identical control instructions, and valid output commands are confirmed through a standard 2-out-of-3 voting algorithm to eliminate single-point failures.

External Interface Description: No dedicated wiring terminals for field digital input (DI) or analog input (AI) signal acquisition; field sensor signals cannot be directly wired to this module.

2. Detailed Output Specifications

2.1 Channel Layout & Redundancy Architecture

Channel Quantity: 16 grouped common digital output channels

Output Form: Active 24 VDC transistor-type supervised digital output

Redundancy Scheme: Full triple modular redundancy covers all output drive circuits

2.2 Electrical Performance Parameters

Rated Field Operating Voltage: 24 VDC

Stable Operating Voltage Range: 16 VDC ~ 30 VDC

Maximum Transient Withstand Voltage: 36 VDC

Typical Channel Voltage Drop: Less than 1.5 VDC per individual channel

Continuous Rated Load Current: 0.7 A for each single channel

Peak Surge Current: 4.8 A with a maximum permissible duration of 10 ms

Minimum Load Detection Current (Diagnostic Threshold): 30 mA

Maximum Off-State Leakage Current: 4 mA

Inter-channel Dielectric Isolation: 1500 VDC isolation rating between separate channels

Overall Maximum Module Power Dissipation: Lower than 10 W

Built-in Hardware Protection: Integrated automatic overload and short-circuit protection; external fuses are not required for routine operation.

2.3 Loop Supervision & Diagnostic Functions

Per-channel continuous real-time circuit monitoring: Capable of identifying open-circuit load loss, short-circuit faults, field power supply failure and wiring disconnection.

Two centralized hardware alarm signals: POWER alarm for abnormal field power status, LOAD alarm for missing loads or circuit breakdowns.

Visual status indicators: PASS for normal self-test status, FAULT for internal hardware malfunction, ACTION for energized output state.

Fail-Safe Design: All output channels will automatically de-energize and switch to a safe off state once module faults are detected.

2.4 Environmental Features & Application Scope

Operating Ambient Temperature Range: -40℃ ~ +70℃

Hot-Swap Compatibility: Supports online hot swapping without system shutdown; outputs maintain predefined safe status during module replacement.

Typical Application Scenarios: Driving solenoid valves, safety trip relays, ESD emergency shutdown actuators and other critical safety field devices.

The module features triple modular redundancy (TMR) structure and is certified SIL3 under IEC 61508 and IEC 61511 SIS industrial safety standards.

It serves as a 16-channel supervised active 24VDC transistor digital output module with no external field input ports.

Exclusive 2-out-of-3 voting logic screens invalid control commands and prevents single-point hardware failures.

Individual channels are equipped with real-time circuit diagnostics to detect open loads, short circuits, power supply dropout and wire breakage.

Built-in overload and short-circuit protection removes the need for externally fitted fuses.

Visual indicators including PASS, FAULT and ACTION are configured, paired with POWER and LOAD fault alarm signals.

It adopts rigorous fail-safe design, whereby all outputs will be automatically disabled once hardware faults emerge.

It operates reliably between -40℃ and +70℃, featuring robust adaptability to harsh working environments.

Hot-swap function enables online module replacement without overall system shutdown.

1500VDC isolation is configured between channels to deliver outstanding anti-interference stability.

Each channel supports 0.7A continuous rated current, 4.8A peak surge current with a 10ms maximum duration, and 30mA minimum load current for diagnostic judgment.

It is engineered to drive core safety field devices, including solenoid valves, safety trip relays and ESD emergency shutdown actuators.
