Pantech Instruments manufactures Signal Isolators and Converters with Predefined Inputs, model 821. Pantech Instruments manufactures Process Control Instruments. These Signal Isolators and Converters with Predefined Inputs is an instrument for providing isolation between input, multiple outputs and power supply. The module is a choice when fanning out of process signal is required. Signal Isolators and Converters with Predefined Inputs provides up to four output signals, each capable of driving of 800 ohms. All these outputs are isolated from each other, input and power supply. This ensures isolation between various subsystems and protects the system from all grounding problems. Signal Isolators and Converters with Predefined Inputs accept any one out of variety of inputs. It accepts a current/voltage/temperature input or 4 - 20mA DC from two wire transmitters or sensor. Signal Isolators and Converters with Predefined Inputs is such designed as it requires only one single positive barrier at the input from a two-wire transmitter for intrinsic safety and isolates the control room. The module also accepts T/C and RTD signals.
The cold junction compensation is built in and up scale burn out is provided as standard features for thermocouple input ranges. Signal Isolators and Converters with Predefined Inputs can be equipped with an intrinsically safe current output. It is equipped with an optional 3- fraction 1/2 digit seven segments LED display for process indication in percentage or engineering units. Signal Isolators and Converters with Predefined Inputs is also facilitated with internal transmitter power supply of 24 V DC, to power up two-wire transmitters.
