Description

The DAP112 is a high-density digital output interface module designed for the legacy Schneider Electric Modicon A120 programmable logic controller system. This module provides 16 independent discrete output channels configured for 24 V DC operation, facilitating reliable signal transmission, actuator control, and relay coil switching in demanding industrial environments such as power generation and petroleum processing. The module incorporates advanced solid-state switching and galvanic isolation to protect the control logic from field-side electrical disturbances.

Features

  • 16 independent discrete output channels.
  • Source-type (positive logic) output configuration.
  • Integrated electronic current limiting for short-circuit protection.
  • Built-in free-wheeling clamping diodes for inductive load suppression.
  • 1500 V AC galvanic isolation between field wiring and the logic bus.
  • Front-panel LED diagnostic matrix for module status, error detection, and individual channel state monitoring.
  • Removable front-accessible terminal block for efficient maintenance.

Applications

The DAP112 is engineered for use in industrial automation systems requiring high-density output control, including:

  • Petroleum and chemical processing installations.
  • Electrical power generation and distribution plants.
  • Mining and material extraction facilities.
  • General-purpose discrete control loops for actuators and solenoid valves.

Installation Guidelines

  • Ensure the PLC system power is disconnected before installing or removing the module from the backplane.
  • Mount the module in an environment compliant with the specified operating temperature (0 to 60 deg C) and humidity (5% to 95% non-condensing).
  • Use shielded cables for field-side wiring to minimize electromagnetic interference (EMI) in high-noise environments.
  • Verify that all field-side loads are within the 0.5 A per channel and 8.0 A total module current limits.
  • Ensure proper grounding of the Modicon A120 rack assembly to maintain the integrity of the galvanic isolation barrier.
  • Handle the module using ESD-safe practices to prevent damage to internal solid-state components.
