Description
The SWS-457 is a simple digital panel indicator intended for displaying any numerical values and characters defined by user (in SLAVE mode only) sent from the master device over the RS 485 serial interface link. The displayed value may be collected from other device (in MASTER mode). User can change display colour in 9 steps range (through light green, yellow and through green) and display brightness in 8 steps range.
The device is equipped with 4 buttons for main presets programming. To get high protection level, the keyboard is mounted under transparent waterproof cover. This feature allows to use SWS-457 in hazardous environments.
To allow user to change presets without opening of cover, an IR sensor is mounted. Remote controller keyboard is equivalent to the device keyboard (Note, that remote controller is not a part of the SWS-457 set. It is an option.).
Modbus RTU protocol is used to communication with device. Baud rate is user defined in 1200 ÷ 115200 baud range. It is possible to order device with other communication protocol using RS-485 interface (special order required).
Two waterproof, high IP protection ratings, wall mounted types of housing are available (T-type and F-type), predispose the device to work in hard environment conditions.
