PHOENIX CONTACT PLC-OPT-110DC/24DC/3RW 2900380 Product Description

Overview

PHOENIX CONTACT PLC-OPT-110DC/24DC/3RW 2900380 is a PLC-INTERFACE solid-state relay module for railway and industrial automation, DIN rail mounted slim interface unit with integrated optocoupler isolation. The PHOENIX CONTACT PLC-OPT-110DC/24DC/3RW accepts 110 V DC control input and provides 24 V DC electronic output up to 3 A, designed to transfer digital signals between high-voltage DC control circuits and low-voltage 24 V DC load sides. This PLC-OPT solid state relay module serves as a reliable Phoenix Contact opto-isolated SSR interface module, widely adopted for signal isolation and load switching in railway vehicle, trackside and industrial control cabinets of the Phoenix Contact opto-isolated SSR interface module.

Features

This PHOENIX CONTACT PLC-OPT-110DC/24DC/3RW adopts optoelectronic isolation structure to separate input and output circuits, eliminating potential ground loop interference for the Phoenix Contact opto-isolated SSR interface module. It features wear-free electronic switching, suitable for high-frequency switching cycles without contact bounce or arcing. The compact 6.2 mm narrow housing saves cabinet space, equipped with screw type terminals for stable wiring. Built-in overvoltage protection on the output side prevents transient voltage damage to downstream sensors and actuators. The PHOENIX CONTACT PLC-OPT-110DC/24DC/3RW supports wide operating temperature range from -25 °C to +70 °C, meeting railway environmental requirements. Front status indicator enables quick visual diagnosis of input signal status of the PLC-OPT solid state relay module.

Principle

PHOENIX CONTACT PLC-OPT-110DC/24DC/3RW 2900380 uses an internal optocoupler to transmit on/off signal without electrical connection between input and output sides. The PHOENIX CONTACT PLC-OPT-110DC/24DC/3RW input 110 V DC signal lights the internal LED of optocoupler, then the phototransistor triggers the output semiconductor switch to turn on the 24 V DC load circuit. When input signal disappears, the optocoupler cuts off and the output switch turns off. The opto-isolation barrier blocks common-mode noise and potential difference between the 110 V DC control loop and 24 V DC field loop. The semiconductor switching structure of the Phoenix Contact opto-isolated SSR interface module achieves silent, long-life switching action.

Applications

This PHOENIX CONTACT PLC-OPT-110DC/24DC/3RW is primarily used in railway rolling stock, trackside control systems, and industrial automation cabinets with 110 V DC control supply. It is applied for isolating and switching solenoid valves, indicator lamps and small DC actuators. It is used for new cabinet assembly and spare replacement for existing railway and industrial control systems. The PHOENIX CONTACT PLC-OPT-110DC/24DC/3RW 2900380 delivers stable galvanic isolation and wear-free DC switching for railway and industrial digital signal interfaces as a proven PLC-OPT solid state relay module.
