II. Core Electrical Parameters

Channel: 4 independent relay outputs

Input voltage: 24VDC or 48VDC

Output voltage: 24VDC or 48VDC, compatible with on-site actuators

Output current: 4A (per channel)

Backplane power supply: 24VDC, typical power consumption ≤ 130mA

Operating temperature: -20℃ to +60℃

Protection / Size: IP20; standard 4TE (approximately 20mm wide), size approximately 40×185×128mm

Weight: approximately 0.32kg to 1kg (slightly different for different batches)

III. Functions and Safety Mechanisms

Safety architecture: Quadruple redundancy (QMR), multiple fault safety implemented within a single module, contacts safely open in case of power loss or failure

Drive capability: Directly drives 24V/48V solenoid valves, small contactors, alarm horns, fire door interlocks, etc.

Self-diagnosis: Full-channel coverage self-diagnosis, detects coil / contact faults, short circuits, open circuits, power abnormalities

Operating mode: Each channel can be configured as fail-safe or non-fail-safe mode

Indicator lights: LED for each state, power/fault indicator lights, facilitating on-site maintenance

Isolation: Electrical isolation between channels, system side and field side, strong anti-interference capability

IV. Typical Application Scenarios

ESD emergency stop system: Key valves, actuator drives

BMS boiler management: Fuel valves, igniters, purge valves control

F&G fire protection system: Alarm horns, sprinkler valves, fire door interlocks

High-reliability interlock: Third-party system dry contact interface, safety barrier post-stage amplification
