TDA 08

ACQUISITION MODULES FOR RS485 NETWORKS

The TDA 04 acquisition module transmitt process measurements via RS485 serial links with MODBUS RTU (JBUS) protocol to either a computer based data acquisition system or to the Tecnologic TMS01 monitoring and recording device. The TDA 08 accepts up to 8 temperature inputs from either PTC or NTC thermistors or Pt1000 RTD’s. The TDA 08, further than transmitting the measure of every channel via RS485, it’s also able to manage directly the signals of high and low alarm for each channel. Each serial connection is capable of handling a maximum of 15 TDA modules for a total of 120 temperature measurements. Each module includes 4 digital inputs for free voltage contacts and one relay output. The digital inputs can be used to transmit, to the supervision system, information about local devices of the plant as for instance status of protection devices, open doors, lights, etc.. The relay output can be used for a local high or low alarm, via serial line or programmino the TDA itself, or can be controlled based on the status of a digital input.
