I/O modules

Product Overview

This input simulator module provides a convenient testing solution for Series 90-30 PLC systems. It allows engineers to verify input logic without connecting actual field devices. The IC693ACC300 generates simulated signals across eight discrete input channels simultaneously. Users can quickly test program responses during commissioning or troubleshooting procedures. This module significantly reduces setup time when validating control logic sequences.

Technical Specifications

The IC693ACC300 measures 12.5 cm in height and 11.4 cm in depth, matching standard Series 90-30 module dimensions. It weighs approximately 0.28 kg, making it highly portable for field testing purposes. This simulator draws 50 mA from the +5 VDC backplane supply. It provides eight toggle switches, each corresponding to an individual input channel. Each switch delivers a dry contact closure to simulate either a 24 VDC or 120 VAC input signal. The module connects directly to the I/O rack backplane through a standard 48-pin connector. A front-panel LED illuminates for each active channel, providing clear visual feedback. The unit includes a removable terminal block for easy wiring access.

Simulation Functions and Operation

This simulator enables users to force inputs on or off during program testing. It replicates real-world sensor conditions without requiring physical actuators or switches. The IC693ACC300 allows simultaneous switching of multiple inputs for complex scenario testing. You can simulate start-up sequences, emergency stops, and interlock conditions effectively. The module does not require external power sources beyond the backplane supply.

Physical and Electrical Parameters

Installation and Usage Guidelines

Install the IC693ACC300 into any available slot within the Series 90-30 I/O rack. Secure the module firmly using the retaining screws at top and bottom positions. Connect the terminal block to your test harness or directly to the PLC input module. Toggle each switch upward to simulate an ON condition for the corresponding channel. The front LEDs will illuminate immediately to confirm each active input state. Remove the module after testing to restore normal system operation.

Typical Applications

This simulator serves machine builders, system integrators, and maintenance technicians. It proves invaluable during factory acceptance testing and on-site commissioning activities. The IC693ACC300 also assists in operator training and troubleshooting exercises. Its simple design makes it an essential tool for any Series 90-30 maintenance toolkit.
