C-WS-0x00R-ABB

The C-WS-0400R-ABB and C-WS-0200R-ABB control unit are also interior push-button control units for ABB designs. A comprehensive family of control units can be fitted with a number of fingerboards designed by ABB, e.g. Time Tango, Neo, Levit ... (for more variants see the Teco catalogue). Each control unit is fitted with an internal temperature sensor, which is located under the fingerboard. It means that the interior temperature can be measured directly, without the need for a separate sensor. However, the measurement accuracy is affected by the fact that the module tends to warm up. Therefore, after switching on and stabilizing the temperature, its correction should be made (the correction parameter is a part of the module configuration in the Mosaic environment).

The CIB bus is connected to the terminal block on the rear side of the module, where also the AI/DI universal inputs are terminated. Each of the universal inputs can be used separately either in the function of binary dry input, or as a balanced input, or as an analogue input for connecting a resistive temperature sensor.

The module is mechanically adapted for mounting on a standard flush box with 60 mm spacing between the fixing screws.

Notes:

1. The temperature sensor can be the Pt1000, NI1000, NTC 12k or any other NTC with a resistance up to 100 kΩ; the feeder cable length can be up to dozens of meters - a typical use is a floor sensor, cable used e.g. SYKFY or similar, with at least 1x2 wires with 1.5 mm.

2. The module is designed as a standard installation element to be mounted on the flush box (KU68).

3. The terminal block is designed for conductors with a max. cross section 1.5 mm².
