– KNX Multi IO: 48 configurable inputs and outputs
– Relay extensions for Multi IO
– New compact KNX IO devices for lighting control and security
Weinzierl Engineering GmbH expands its KNX IO range of products. The two KNX Multi IO devices 570 and 580 each offer 48 freely configurable inputs and outputs. The relay extensions KNX IO 590 and 592 form the logical complement to the new Multi IO devices – and the compact KNX IO range (18mm width) is extended by five new devices for lighting control and security.
KNX Multi IO: 48 universal channels for control
The KNX Multi IO 570 is a universal input and output module for building control. It offers 48 digital channels. Each channel can be used as a binary input or as a binary output. The periphery (e.g. relay) is powered by an external power supply (24V DC). Input channels may be used to control e.g. of lights or blinds via KNX. They can also be configured as pulse counters, for example for energy meters. Output channels can directly control signal LEDs, external coupling relays (e.g. KNX IO Extension 590) or blind relays (e.g. KNX IO Extension 592).
The integrated USB interface allows a connection between a PC and the KNX bus. The USB connection is galvanically isolated from the KNX bus. The configuration is done with the ETS (version 4.2 or higher), local programming via USB is also possible. An easy-to- read OLED display on the front allows manual operation and diagnostics.
The KNX Multi IO 580 IP corresponds in function to the KNX Multi IO 570 TP, but is connected to the installation via LAN / Ethernet. The device thus uses the medium KNX IP and can be integrated into a network parallel to KNX IP routers. It appears in the ETS (version 4.2 or higher) as usual with parameters and communication objects. The KNX addressing, based on physical address and group addresses, also remains unchanged.
Extensions for Multi IO: Relay extensions with system
KNX Multi IO 570 TP and KNX Multi IO 580 IP allow the connection of commercial standard coupling relays to the switching outputs. The KNX IO Extension 590 serves as a power-saving alternative. The coupling relay is controlled as a mono-stable relay, but uses a bi-stable relay internally, thus reducing the holding current by up to 95%.
The KNX IO Extension 592 has been specially developed for the control of blinds or shutters. The double relay is connected to only one output of a KNX Multi IO and integrates the relay outputs for both directions. The outputs are electro-mechanically locked against each other. Both KNX IO Extensions have an integrated fuse to protect high-quality equipment.
KNX IO 1TE: growth in lighting control and security
The compact KNX IO range with a width of 1TE is now receiving multiple additions in the area of lighting control and security. The KNX IO 530 is a dimmer for 230 Volt bulbs and also offers two integrated binary inputs. The KNX IO 532 is a compact combined dimming / switching actuator with a PWM output for dimming LEDs with (12-24 V) and a bi-stable relay output. The model KNX IO 534 offers a total of four PWM outputs for dimming RGB LEDs or for setting the color temperature (tunable white). The KNX IO 546 is a dimmer for 0-10 volt ballasts and additionally offers a bi- stable relay output. In addition to the control of the dimmers by switching, relative dimming and dimming value, several optional functions are integrated, including scenes, automatic, snooze function or staircase lighting. Two buttons and three LEDs allow local operation and visualization of the respective device status.
With the KNX IO 511 secure, Weinzierl is expanding its product range of the IO product family by a device with support for KNX Data Security. The compact switch actuator with one bi-stable output and two binary inputs provides functions for universal outputs including scene switching, on/off delay, staircase light switching and control of heating valves (PWM for thermal actuators).
The inputs can be controlled via conventional switches with an external voltage of 12 to 230 V. The actuator together with input B1 serves as an impulse switch. Input B2 is for zero crossing detection. The configuration is encrypted with the ETS5. All data points can communicate either securely or unencrypted. Due to the small footprint, the KNX IO series allows a high degree of flexibility in the planning and design of the electrical distribution.
The new devices and solutions will be shown at Light Building 2018 in Frankfurt (Hall 9.1 / Stand A90).
