MTL5582 Safety Barriers MTL5582 Resistance Isolator to Repeat RTD Signals
The MTL5582 connects to a 2-, 3-, or 4-wire resistance temperature device (RTD) or other resistance located in a hazardous area, isolates it and repeats the resistance to a monitoring system in the safe area. The module is intended typically (but not exclusively) for use with Pt100 3-wire RTDs. Switches enable selection of 2-, 3-, or 4-wire RTD connection. The MTL5582 should be considered as an alternative, nonconfigurable MTL5575, for use in RTD applications where a resistance input is preferred or needed instead of 4/20mA. The design is notable for its ease of use and repeatability. The number of wires which can be connected on the safe-area side of the unit is independent of the number of wires which can be connected on the hazardous-area side. The module drives upscale in the case of open circuit detection. Note that this module is not suitable for use with measurement systems where the resistance input channels are multiplexed.
Temperature Input module of MTL5582 Safety Barriers MTL5582 Resistance Isolator to Repeat RTD Signals
These modules accept inputs from low-level dc sources such as thermocouples or RTDs in hazardous
areas and converts them into 4/20mA signals to drive safe area loads.
Early burnout detection (EBD) of MTL5582 Safety Barriers MTL5582 Resistance Isolator to Repeat RTD Signals
When EBD is selected, the resistance of the thermocouple circuit is monitored and an alarm is
raised when there is an increase of more than 50m. This enables preventative maintenance to be
conducted on the field installation before the thermocouple actually breaks.
Configuration using PCS45/PCL45USB of MTL5582 Safety Barriers MTL5582 Resistance Isolator to Repeat RTD Signals
Use PCS45 software, in conjunction with the PCL45USB serial link, to configure these modules. Instructions
are contained within the software.
