IC694MDL660

What type of input signals is this module designed for?

It is a discrete input module designed for 24 V dc input signals, with a stated input range of 0 to 30 V dc. It is typically used to read on/off signals from devices such as sensors, limit switches, pushbuttons and auxiliary contacts.

How many input points does this module provide?

This is a high-density 32-point input module, allowing a large number of discrete field signals to be connected in a single RX3i rack slot.

What PLC platform is it used with?

The IC694MDL660 is part of the PACSystems RX3i I/O range and is intended for use in compatible RX3i rack-based PLC systems.

Is this an analogue or digital module?

It is a digital, or discrete, input module. It reads binary field states, such as ON/OFF or energised/de-energised conditions, rather than variable analogue signals.

What does high-density mean for this module?

High-density refers to the module’s ability to accommodate 32 input channels in a compact format. This helps reduce rack space where many 24 V dc input points are required.

What is the typical input current for this module?

The listed input current is 7 mA, which should be considered when assessing sensor loading, field power supply capacity and total panel current requirements.

Can it be used in machine automation applications?

Yes. It is commonly suited to machine control and general automation tasks where multiple 24 V dc discrete input signals need to be monitored by an RX3i PLC system.

Does it mount directly into an RX3i rack?

Yes. It is a rack-mounted I/O module for compatible PACSystems RX3i installations. It is designed to be installed with other RX3i power supply, CPU, communication and I/O modules as part of a complete PLC system.

What accessories may be relevant when installing this module?

Relevant RX3i accessories can include terminal blocks and door labels for IC694-series I/O modules. Selection depends on the rack configuration and the wiring method used in the control panel.

What are typical applications for this input module?

Typical applications include monitoring proximity sensors, photoelectric sensors, selector switches, pushbuttons, relay contacts, interposing relay outputs and other 24 V dc discrete field devices.

Is it suitable for compact panel designs?

Yes. Because it provides 32 input points in a high-density format, it can help reduce the number of separate input modules required in applications with many discrete signals.

What should be checked before installing this module?

Before installation, check the RX3i rack compatibility, input voltage level, wiring arrangement, terminal block requirements, field power supply capacity and the intended I/O addressing within the PLC configuration.
