Technical Specifications 8 digital input channels, 8 digital output channels; 24V DC nominal signal voltage; input threshold: 15V DC minimum for logic high; output: solid-state, 0.5A per channel; 24V DC module power; operating temperature: -40°C to +70°C.
Functional Features Discrete signal acquisition; solid-state output switching; per-channel status indication; input filtering; output short-circuit protection.
Application Scenarios Status monitoring of auxiliary equipment, alarm indication output, control system discrete interface, machinery status annunciation.
Performance Parameters Fast input response; reliable output switching; stable operation over temperature range; high channel isolation.
Material Composition Industrial plastic housing, digital I/O circuit board, solid-state output devices, gold-plated backplane connector.
Structural Characteristics Rack plug-in module, front channel status LEDs, rear terminal block, system backplane interface.
Working Principle Monitors the on/off state of field discrete devices and transmits status to the system controller. Receives output commands from the controller and switches solid-state outputs to control external indicator and control circuits.
Installation Requirements Install in system I/O rack slot; connect field wiring to rear terminal block; verify signal voltage matches module rating.
Usage Notes Do not exceed output current rating; use surge suppression for inductive loads; inspect input wiring for ground faults.
