Pantech's Signal Isolator, model 821 is an ideal instrument for providing isolation between input, multiple outputs and power supply. The module is an ideal choice when fanning out of process signal is required. It 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.
The module accepts any one out of variety of inputs. It accepts a currentvoltagetemperature input or 4 – 20mA DC from two wire transmitters “or” sensor. The unique design of the module 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 TC and RTD signals. The cold junction compensation is built in and up scale burn out is provided as standard features for thermocouple input ranges. As well as it can be equipped with an intrinsically safe current output.
