WEINZIERL Multi IO Extension Switch 590

Description

Introduction

The WEINZIERL Multi IO Extension Switch 590 is a 1-module (18 mm wide) DIN rail 230 V switching actuator designed as an energy-efficient alternative to standard commercial coupling relays. Operating with a 24 V DC signal input while driving a 230 V AC output, this compact switching module is engineered to integrate smoothly with building control equipment such as the KNX TP Multi IO 570 and KNX IP Multi IO 580. This device is part of our KNX Actuators range.

By utilizing an internal bi-stable relay while responding to mono-stable control signals, the device reduces holding current by up to 95% down to under 2 mA. Equipped with an integrated 10 A glass fuse and a green LED state indicator, it provides reliable output switching and protection. When procuring for project BOQs with limited specifications, verify exact technical documentation to prevent incorrect orders.

Key Features

• 1 module (18 mm) DIN rail mounted plastic enclosure.
• 24 V DC input signal via 2-pole screw terminal.
• 230 V AC / 16 A bi-stable relay output via 3-pole screw terminal.
• Holding current reduced to less than 2 mA.
• Integrated 10 A (5×20 mm) glass fuse.
• Green LED status indicator for relay state and fuse.
• Designed as an accessory for KNX TP Multi IO 570 (48I/O) and KNX IP Multi IO 580 (48I/O).

Benefits

• High Energy Efficiency: Uses an internal bi-stable relay to cut holding current by up to 95% (< 2 mA) compared to conventional coupling relays.
• Compact DIN Rail Design: Fits in a single module space (18 mm width) weighing approximately 50 g, optimizing cabinet space.
• Integrated Circuit Protection: Built-in 5×20 mm 10 A glass fuse protects connected load circuits and high-quality equipment.
• Visual Status Monitoring: Features a green LED indicator for clear operational state and fuse status verification.
• Flexible Relay Options: Supports alternative factory relay variants for specialized needs such as high inrush LED loads or manual override.

Applications

• Energy-saving switching extension for KNX TP Multi IO 570 and KNX IP Multi IO 580 systems.
• Sub-distribution panel switching where low coil power dissipation and minimal width are required.
• Inrush-tolerant load switching when used with dedicated tungsten relay variants for LED lighting.

Installation Notes

• Mount the 18 mm plastic housing on a standard 35 mm DIN rail inside the distribution cabinet.
• Connect the 24 V DC control signal to the 2-pole input screw terminal and the 230 V AC load circuit to the 3-pole output screw terminal.
• Ensure output loads do not exceed the 10 A integrated fuse capacity, taking into account capacitive or inductive switching power reductions.
