PMA TB45 Tem­per­a­ture lim­iter for DIN rail mount­ing

The PMA TB45 is sup­plied as a stand-alone tem­per­a­ture limiter/monitor or limit value indi­ca­tor with optional Mod­bus inter­face or as a sys­tem com­po­nent with ver­sa­tile com­mu­ni­ca­tion con­nec­tions via the bus cou­plers of the Rail Line sys­tem. This means that the lim­iter can be eas­ily inte­grated into a cen­tral con­trol sys­tem. Its mea­sured val­ues can also be used by other func­tions. There is elec­tri­cal iso­la­tion between the inputs and out­puts as well as to the aux­il­iary power and the com­mu­ni­ca­tion inter­faces.

 

The PMA TB45 is used for both heat­ing and cool­ing processes and is suit­able for all ther­mo­cou­ples and resis­tance sen­sors.

 

Prop­er­ties

  • Con¬≠fig¬≠urable as a lim¬≠iter, mon¬≠i¬≠tor or limit value indi¬≠ca¬≠tor
  • Com¬≠pact design, only 22.5 mm wide
  • Can be snapped onto top-hat rail
  • Plug-in screw or spring-loaded ter¬≠mi¬≠nals
  • Two-line LCD dis¬≠play with addi¬≠tional dis¬≠play ele¬≠ments
  • Con¬≠ve¬≠nient 3-but¬≠ton oper¬≠a¬≠tion
  • Com¬≠mu¬≠ni¬≠ca¬≠tion capa¬≠bil¬≠ity with wire¬≠less cross-con¬≠nec¬≠tion in top-hat rail
  • Blue¬≠Port¬ģ front inter¬≠face
  • Two uni¬≠ver¬≠sal inputs (only for device ver¬≠sion TB45-1)
  • Two relay out¬≠puts
  • Two pre-alarms
  • Uni¬≠ver¬≠sal out¬≠put for dis¬≠play val¬≠ues

 

 

Typ­i­cal areas of appli­ca­tion for the PMA TB45:

  • Sys¬≠tems in which exceed¬≠ing or falling below a cer¬≠tain tem¬≠per¬≠a¬≠ture leads to dam¬≠age
  • Heat gen¬≠er¬≠a¬≠tion sys¬≠tems with flow tem¬≠per¬≠a¬≠tures up to 120 ¬įC in accor¬≠dance with DIN 4751
  • Hot water sys¬≠tems with flow tem¬≠per¬≠a¬≠tures of more than 110 ¬įC in accor¬≠dance with DIN 4752
  • Heat trans¬≠fer sys¬≠tems with organic heat trans¬≠fer media accord¬≠ing to DIN 4754
  • Oil fir¬≠ing sys¬≠tems accord¬≠ing to DIN 4755

 

 

Dis­play and oper­a­tion

The two-line LCD dis­play allows the limit value, the mea­sured value and the com­plete oper­a­tion of the PMA TB45 to be dis­played. An LED and four other dis­play ele­ments reli­ably indi­cate the oper­at­ing sta­tus, oper­at­ing mode and error mes­sages. The unit of the mea­sured vari­able can be shown in the dis­play and can also be defined on a cus­tomer-spe­cific basis. Via the extended oper­at­ing level
any sig­nals and para­me­ters can be dis­played in the 2nd dis­play line

 

 

Inter­face and engi­neer­ing tool

Set¬≠tings can be made via the front panel as well as via the Blue-Port¬ģ front inter¬≠face and the Blue¬≠Con¬≠trol¬ģ soft¬≠ware.

Blue¬≠Con¬≠trol¬ģ and Blue-Port¬ģ are reg¬≠is¬≠tered trade¬≠marks of PMA Proze√ü- und Maschi¬≠nen-Automa¬≠tion GmbH
