BARD-400A | YOKOGAWA Barrier Module

Tne BARD shun-type Intrinsic Sajety Barrier is used as an interjace between hazardous and non-hazardous areas. It maintains intrinsic safety by limiting the cur- rents and voltages which enter the hazardous area.
This safety barrier has a two-part.construction: the main body of the barrier plugs into a terminal block.
This facilitates installation and maintenance.
Three types of BARD Safety Barriers are available one for use with thermocouples, one for RTDs (Resistance Temperature Detectors) and one for 4 to 20mA current loops of 2-wire transmitters and controller outputs. Double element thermo- couples may also be used.
