Product Details Introduction

1771-IQC Digital Input Module Core Introduction

1771-IQC is an 8-channel 5-30V DC configurable digital input module of the Rockwell PLC-5 series, supporting source/drain switching, designed specifically for industrial field DC switch and sensor signal acquisition, compatible with 1771 standard I/O rack.

Model: 1771-IQC, PLC-5 series 8-point DC digital input module.

Input type: 8-channel 5-30V DC discrete input, can be switched between source/drain connections through dip switches (SW1/SW3).

Voltage specification: Rated 5-30V DC, compatible with industrial standard DC sensors and switch signals.

Input characteristics: turn-on voltage ≥ 40% of rated value, turn off voltage ≤ 20% of rated value; Input impedance of 1.2k Ω.

Response time: Standard mode typically 12ms (5-26ms); When SW1 is set to OFF, the maximum time for fast mode is 1ms.

Isolation protection: The channel and backplane are electrically isolated, with a withstand voltage of 1500V DC, meeting industrial safety standards.

Power consumption: The backplane is powered by 5V DC, with a maximum current of 150mA; the full load power consumption is about 6.8W.

Physical installation: occupying one 1771 rack slot, supporting rack installation, equipped with 1771-WC wiring arm.

Status indication: Each channel has independent LEDs that display real-time input on/off status.

Compatible platform: compatible with PLC-5/11, PLC-5/20, PLC-5/30, PLC-5/40, PLC-5/80 and other controllers.

Environmental parameters: working temperature 0-60 ° C, humidity 5% -95%, no condensation, industrial grade anti-interference design.

Certification compliance: Passed industrial safety and EMC certifications such as UL and CE.

Application scenarios: DC signal acquisition scenarios for machine tools, automated production lines, material conveying, packaging equipment, etc.

Product status: discontinued, mainly for refurbishment/spare parts in the market, used for maintenance of PLC-5 old systems.

1771-IQC is a classic module for DC digital signal access in PLC-5 systems, characterized by flexible configuration, fast response, and high isolation. It is suitable for upgrading and maintaining old industrial control systems that require compatibility with different wiring methods.
