Short Description
Description:
The 1769-IG16 is a 16-point digital input module for Rockwell Automation's CompactLogix and MicroLogix 1500 series.
It is designed to work with 5V DC TTL-level signals, making it perfect for applications that require fast, low-voltage digital inputs.
Input type: 16 TTL-compatible digital inputs (current source).
Voltage range: 4.5–5.5 VDC.
Signal type is TTL (Transistor-Transistor Logic).
Backplane Current Draw: 250 mA at 5 V DC.
Isolation voltage: 30 volts (continuous), basic insulation.
Mounting options include DIN rail or panel mount with CompactLogix controller.
Status Indicators: LEDs for each input channel.
