Industrial Applications

1. Small machine sequencing with mixed relay loads

A compact machine controller needing 24 VDC field inputs and relay outputs for solenoids, lamps, and contactor coils can use the integrated 24/16 I/O and relay stage directly.

Problem Solved

Eliminates separate interposing relays for many low-power loads while keeping wiring simple in a small panel.

2. Distributed equipment with Ethernet supervision

A compact OEM system can be networked through the built-in Ethernet TCP/IP port for HMI, SCADA, or remote maintenance without adding a communication module.

Problem Solved

Provides native industrial Ethernet connectivity in a small PLC footprint.
