The COOKIE-AD input interface is designed to measure the signal of an analogue sensor and simultaneously read the contact input on the same interface. The compact housing is specifically useful for installations where space is limited and AUTOBUS is available. It also avoids that the sensor signal needs to be transported over long wires to the electrical board. The 4-20mA input has the advantage that in case of a broken signal wire, the TDS system can detect this and takes action.

The TDS12301 is a compact input interface with one universal analogue and one digital input. The digital input can be used to connect Voltage free contacts like from a push button, door- or window contact, presence detector, etc. (any brand). The analogue sensor input can be connected to sensors like T° sensor from a sauna, water T° , Ph or Chlore sensor of a swimming pool, wind speed sensor, etc... The following analogue signal types are supported: 0 - 5V, 0 -10V, 0 - 20mA, 4 - 20mA (with cable break detection alarm), PT100 sensor (3-wire) and the TELETASK T°, Light and Humidity level sensors TDS12250, TDS12251, TDS12260 and TDS12270.
