Product Description

The compact 7AF104.7 I/O module provides a convenient interface for integrating on/off field devices into PLC systems. With 4 built-in NPN transistor outputs, it enables straightforward control of solenoids, lights, contactors, alarms, and more in automation applications. Despite its diminutive 3.3 x 4.5 x 2.3 inch footprint, the module leverages space-saving design to pack useful functionality. Screw terminal connectors allow rapid installation of external wiring. The adapter interface enables placement across up to 4 system slots for flexible system planning. Construction utilizes durable plastic housing that meets IP20 ingress rating standards for indoor use, shielding the electronics against dust and light splashing while maintaining a lightweight 7 ounce module that won't overburden rails. Screw clamps ensure solid, vibration-resistant wire connections.

The 7AF104.7 transistor output solution may date from an obsolete product phase, but it still provides handy interfacing for small-scale control tasks. The open-collector NPN outputs switch up to 30V DC loads with instant response times to PLC actuation signals. Just note that continuous current capacity varies by application, so consult our team to verify specifications. With field wiring simplicity, wide-ranging use cases, and ultra-compact sizing, this I/O module removes hurdles when integrating basic on/off field devices into new or existing automation systems. Deploy it as a space-saving remote chunk of output capacity perfect for distributing control nearer devices. Or utilize it in tight cabinet confines to expand output availability without consuming much real estate.

Either way, the adaptability, protected construction, and plug-and-play integration capabilities render this transistor output module a useful interface building block for machine builders and plant engineers alike. It durably and reliably handles basic on/off device actuation tasks while letting the main PLC focus resources on managing advanced automation system processes.
