Phoenix Contact PLC-OSC-24DC/230ACACT Solid State Interface Relay, 24V DC Input, 24-253V AC Output, 0.75A

The Phoenix Contact PLC-OSC-24DC/230ACACT is a high-performance solid-state interface relay designed for reliable signal switching in industrial automation environments. This module integrates a 24V DC input with a 24-253V AC output, capable of handling a maximum switching current of 0.75A. Engineered for durability and efficiency, it provides essential electrical isolation between the control and load circuits, ensuring stable operation in demanding control systems and PLC applications that require frequent switching cycles.

Advantages

This solid-state relay module offers significant operational benefits, including the ability to connect actuators directly to the relay module, which simplifies wiring architecture. By eliminating the need for additional modular terminal blocks, users can achieve time savings of up to 60 percent during installation. The design supports efficient connection to system cabling via V8 adapters and utilizes functional plug-in bridges for streamlined configuration. Furthermore, the module provides safe electrical isolation between the coil and contact in accordance with DIN EN 50178 standards, while its compact footprint allows for space savings of up to 80 percent on the DIN rail.

Suitable for

• Industrial automation control systems
• PLC output interface applications
• Switching AC loads up to 0.75A
• Applications requiring high-frequency switching cycles
• Space-constrained electrical cabinets

When it may not be suitable

This relay is not intended for switching DC loads, as it is specifically designed for AC output applications. Additionally, it may not be suitable for high-power industrial loads exceeding the 0.75A current rating, as this could lead to component failure or overheating.

Key specifications

• Input voltage: 24V DC
• Output voltage range: 24V to 253V AC
• Maximum switching current: 0.75A
• Contact type: 1 N/O contact
• Mounting type: DIN rail NS 35/7.5
• Connection method: Screw connection

How to use

The module is designed for mounting on a standard NS 35/7.5 DIN rail. Begin by snapping the PLC-BSC basic terminal block onto the rail. Connect your 24V DC control signal to the input terminals and your AC load circuit to the output terminals using the integrated screw connections. Ensure that the solid-state relay is properly seated in the base terminal block. For larger systems, utilize the V8 adapter for efficient system cabling and employ plug-in bridges to distribute power or signals across multiple modules as needed.

What to consider before purchase

• Verify that your control signal is 24V DC.
• Ensure the load circuit operates within the 24-253V AC range.
• Confirm that the load current does not exceed 0.75A.
• Check available DIN rail space in your control cabinet.
• Ensure compatibility with your existing system cabling if using V8 adapters.

Usage recommendations

Always ensure that the power supply is disconnected before performing any wiring or maintenance on the relay module. Verify that the load current and voltage specifications are strictly adhered to, as exceeding these limits may cause permanent damage to the solid-state components.
