1771-OZL processor module

1771-OZL processor module  

Product Details Introduction

1771-OZL is not a processor module, but an 8-point reed relay isolation output module from the Rockwell Allen Bradley PLC-5 series, designed specifically for low voltage, low power, and strong isolation industrial scenarios.

1771-OZL core parameters (plain text, no links)

Model: 1771-OZL, PLC-5 series 8-channel reed relay output module.

Output type: 8-way normally open (N.O.) reed relay contacts, 4 sets x 2 points, each set independent common terminal.

Voltage range: 0-24V AC/DC universal, suitable for low-voltage control circuits.

Current capability: Single channel maximum continuous 100mA; minimum load 10mA (24V) to avoid false triggering.

Isolation performance: 1000V AC isolation between contacts/contacts logic side; Coil contact 1500V AC isolation.

Power specification: Single channel rated 2.4W; surge impact is strictly prohibited, otherwise it may damage the reed switch.

Power supply and power consumption: The backplane is powered by 5V DC, with a current of 420mA and a power consumption of approximately 2.1W.

Status indication: 8 independent LEDs display the on/off status of the output.

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

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

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

Certification compliance: UL, CE industrial safety and EMC certification.

Application scenarios: Low voltage isolation control for instruments, sensors, small solenoid valves, indicator lights, safety circuits, etc.

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

1771-OZL has the core advantages of full isolation, reed tube sealing, low voltage and low power, and anti-interference, making it suitable for old PLC-5 systems with high requirements for isolation and reliability.
