1771-OAD AC output module  

Product Details Introduction

Introduction to the Core of 1771-OAD AC Output Module

1771-OAD is a 16-point 10-138V AC digital output module of the Rockwell PLC-5 series, which uses zero crossing triggering technology and is designed specifically for driving AC loads such as contactors, solenoid valves, indicator lights, etc. It is compatible with the 1771 standard I/O rack.

Model: 1771-OAD, PLC-5 series 16 channel AC digital output module.

Output type: 16 point discrete AC output, single channel independent fuse protection.

Voltage specifications: rated 10-138V AC, frequency 47-63Hz, compatible with industrial standard power frequency.

Output current: Single channel maximum 2A, module total continuous current ≤ 8A.

Trigger method: Zero crossing trigger, conduction delay of 10ms at 50Hz, 8.3ms at 60Hz, to reduce current surge.

Isolation protection: Channel and backplane are optically isolated, with a withstand voltage of 1500V DC and built-in MOV and RC surge suppression.

Power consumption: The backplane is powered by 5V DC, with a current of 295mA and a power consumption of approximately 1.475W.

Physical installation: occupying one 1771 rack slot, equipped with 1771-WH standard wiring arm.

Status indication: Each channel has an independent LED that displays the on/off and fuse status of the output.

Compatible platform: Suitable for 1771-A1B/A2B/A3B/A4B, AM1/AM2 chassis, PLC-5 full series controllers.

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

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

Application scenarios: AC load control scenarios such as machine tools, packaging, material conveying, HVAC, etc.

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

1771-OAD is a classic module driven by AC actuators in PLC-5 systems, characterized by high density, high power, zero crossing triggering, and strong anti-interference. It is suitable for stable operation and maintenance of old industrial control systems.
