Technical Specifications： Output Channels: 16-channel isolated digital output; Output Type: Transistor source output; Rated Output Voltage: 24 V DC; Single Channel Maximum Current: 0.5 A; Total Module Maximum Current: 4 A; Isolation Voltage: 250 V AC channel-to-backplane; Operating Temperature: -20 ℃ to +70 ℃; Storage Temperature: -40 ℃ to +85 ℃; Mounting: Rack plug-in type.

Functional Features： 16-channel high-density output design to save equipment cabinet space; Per-channel optocoupler isolation to prevent field faults from spreading to the control system; Independent LED status indicator for each channel for on-site fault diagnosis; Built-in per-channel overcurrent and short-circuit protection; Supports online hot-swap without affecting the normal operation of other modules of the system.

Application Scenarios： Semiconductor wafer processing equipment discrete actuator drive; Cleanroom equipment solenoid valve control; Industrial automation production line logic output; Electronic manufacturing equipment status indication and interlock control; Process equipment peripheral actuator drive.

Performance Parameters： Output Switching Delay: ≤ 0.5 ms; Short-circuit protection response time ≤ 1 ms; Channel-to-channel isolation 500 V; MTBF > 500,000 hours; Output leakage current < 0.1 mA in off state.

Material Composition： Flame-retardant industrial plastic panel; FR-4 industrial grade printed circuit board; gold-plated backplane connector; optocoupler isolation components; high-power transistor output devices.

Structural Features： Standard 1381 series rack card structure; front panel channel status LED array; rear side high-density backplane bus connector; built-in mechanical anti-mis-insertion key slot; integrated heat dissipation structure for long-term stable operation.

Working Principle： Receives logic control commands from the host controller through the backplane bus, drives the internal optocoupler and output transistor to turn on or off after logic processing, so as to control the power on and off of field actuators. The built-in protection circuit detects the output current in real time, and automatically cuts off the output channel and uploads the fault signal when overcurrent or short circuit occurs.

Installation Requirements： Install into the dedicated TEL equipment rack slot; the control cabinet must be reliably grounded; field output wiring uses copper conductors with appropriate wire diameter; separate power wiring and signal wiring routing; reserve heat dissipation clearance around the module; operate with anti-static measures during installation.

Precautions： Do not exceed the single-channel current rating and total module current limit; inductive loads must be connected with freewheeling diodes in parallel; avoid direct short circuit of output terminals; do not apply reverse voltage to output terminals; perform regular functional testing according to equipment maintenance specifications.
