8-channel Programmable Indicator TC800♦ 8 inputs, 8 outputs, and 16 alarms♦ 2 displays ─ for measured value and for channel number♦ Programmable ranges and alarms ♦ Self-testing and system-failure alarm♦ RS485 serial interface available The TC800 indicator is designed for multi-point control of technological variables. With its compact design, 8 inputs and outputs, TC800 successfully performs all the tasks of indicating, monitoring, and signaling the level of several channels. With the proper programming, any of the channels may be turned into a 2-or 3-state ON/OFF controller and even into a multistage controller. Motorized actuators may be controlled by using 2 relay outputs. The device input accepts thermoresistances, thermocouples, or standard current and voltage signals. Additional discrete inputs are available for remote channel switching and tampering protection. TC800 performs digital compensation for RTD sensor line resistance as well as thermocouple cold-junction compensation, and constantly monitors sensor and sensor-lead state. A rich set of parameters allows programming every aspect of controller operation and an RS485 serial interface allows network operation or connection to operator station.
