I/O modules

Product Overview

This relay output module provides eight isolated outputs for controlling external AC and DC loads. It interfaces directly with the Series 90-30 programmable controller for industrial automation applications. The IC693MDL930 switches field devices such as contactors, solenoids, and indicator lamps. Each output features a Form A (normally open) relay contact for reliable load control. This module offers robust isolation between the logic circuits and field wiring.

Technical Specifications

The IC693MDL930 measures 12.5 cm in height and 11.4 cm in depth, conforming to standard Series 90-30 dimensions. It weighs approximately 0.36 kg, including all internal relays and terminal hardware. This module draws 300 mA from the +5 VDC backplane supply during normal operation. It provides eight relay outputs with a contact rating of 2 A at 120 VAC or 24 VDC. Each relay supports a maximum inrush current of 5 A for motor and solenoid loads. The output response time measures 15 ms typical for both energizing and de-energizing actions. The module incorporates mechanical relay life of 100,000 operations at rated load. It also provides LED indicators for each output channel status.

Output Characteristics and Wiring

This module uses replaceable plug-in relays for simplified maintenance and repair. It features screw-type terminal blocks with clear labeling for each output and common connections. The IC693MDL930 supports both AC and DC load voltages up to 240 VAC or 30 VDC. Each channel includes a suppression diode for DC loads to reduce contact arcing. Users can wire outputs individually with shared commons for each group of four channels.

Physical and Electrical Parameters

Installation and Operational Guidelines

Install the IC693MDL930 into any available slot within the Series 90-30 I/O rack. Secure the module firmly using the retaining screws at the top and bottom positions. Connect the field wiring to the screw terminals with appropriate torque specifications. Ensure each load current does not exceed the contact rating for reliable operation. The CPU automatically maps outputs to the assigned address upon power-up. Monitor each channel status through the front-panel LED indicators during operation.

Typical Applications

This relay module controls motor starters, solenoid valves, and alarm annunciators. It serves packaging machines, conveyor systems, and material handling equipment. The IC693MDL930 also drives pilot lights, heaters, and small power contactors. Its eight-point density suits applications requiring moderate output capacity.
