Description
458/SW8 8-Channel Switching Module
The 458/SW8 8-channel switching module contains 8 relay channels (normally open), capable of switching 16A per channel.
It uses high inrush relays to withstand short-lived high peak current inrush when switching on loads.
It has both a DALI and an S-DIM/DMX interface, and therefore can be fully integrated into a Digidim or an Imagine router system.
The front of the module is equipped with an LCD display and keypad to set basic configuration parameters and provide basic
control of channel and output levels.
The module is easily fitted to a Digidim 458Mx mechanical chassis, in which each load channel is protected by an individual MCB.
Note: The 458/SW8 modules are supplied separately from the 458Mx mechanical chassis.
Key Features
- Easily attached to a 458Mx chassis and connected to the mains supply for quick installation.
- LCD display screen and a 5-button keypad for monitoring, configuration and manual control.
- Universal mains power supply (85-264 VAC, 45-65 Hz).
Options Module
There is an internal connection for an options module, which is sold separately.
The options module is used to convert 4 channels into either:
- 1 - 10 V → sink, 50 ballasts drive
- DSI (Digital Signal Interface) → 10 ballasts drive
- PWM (Pulse Width Modulation) → 10 ballasts drive
- DALI broadcas t → 10 ballasts drive
Installation Notes
This involves removing the cover from the chassis.
Do NOT connect DALI and S-DIM or DMX at the same time.
Refer to the 458/SW8 Installation Guide and 458Mx Chassis Installation Guide for details.
