Description

Product Description

The IC693MDR390 is a combination discrete I/O module from GE Fanuc for the Series 90‑30 PLC platform, integrating 8 DC input channels and 8 relay output channels in a single compact unit. Designed for applications that require both sensing and switching, the module supports positive or negative logic for inputs and normally‑open relay outputs capable of switching AC or DC loads. Status LEDs provide real-time indication for all 16 points, while compatibility with 24 VDC field devices ensures versatile deployment across industrial automation systems.

Key Features

• 8 DC inputs (single common) with positive/negative logic support

• 8 normally‑open relay outputs grouped in two sets of four

• Input range: –30 to +32 VDC; supports sourcing and sinking devices

• Relay output range: 5–30 VDC or 5–250 VAC, 2 A per output, 4 A per common

• Fast response: 7 ms input, 15 ms output typical

• LED indicators for each input and output point

• Installs in any I/O slot of 5‑ or 10‑slot Series 90‑30 baseplates

• Compact and lightweight design (~0.31 kg / 0.69 lb)
