PMA TB45 TemÂperÂaÂture limÂiter for DIN rail mountÂing
The PMA TB45 is supÂplied as a stand-alone temÂperÂaÂture limiter/monitor or limit value indiÂcaÂtor with optional ModÂbus interÂface or as a sysÂtem comÂpoÂnent with verÂsaÂtile comÂmuÂniÂcaÂtion conÂnecÂtions via the bus couÂplers of the Rail Line sysÂtem. This means that the limÂiter can be easÂily inteÂgrated into a cenÂtral conÂtrol sysÂtem. Its meaÂsured valÂues can also be used by other funcÂtions. There is elecÂtriÂcal isoÂlaÂtion between the inputs and outÂputs as well as to the auxÂilÂiary power and the comÂmuÂniÂcaÂtion interÂfaces.
The PMA TB45 is used for both heatÂing and coolÂing processes and is suitÂable for all therÂmoÂcouÂples and resisÂtance senÂsors.
PropÂerÂties
- ConÂfigÂurable as a limÂiter, monÂiÂtor or limit value indiÂcaÂtor

- Can be snapped onto top-hat rail
- Plug-in screw or spring-loaded terÂmiÂnals
- Two-line LCD disÂplay with addiÂtional disÂplay eleÂments
- ConÂveÂnient 3-butÂton operÂaÂtion
- ComÂmuÂniÂcaÂtion capaÂbilÂity with wireÂless cross-conÂnecÂtion in top-hat rail
- BlueÂPort® front interÂface
- Two uniÂverÂsal inputs (only for device verÂsion TB45-1)
- Two relay outÂputs
- Two pre-alarms
- UniÂverÂsal outÂput for disÂplay valÂues
TypÂiÂcal areas of appliÂcaÂtion for the PMA TB45:
- SysÂtems in which exceedÂing or falling below a cerÂtain temÂperÂaÂture leads to damÂage
- Heat genÂerÂaÂtion sysÂtems with flow temÂperÂaÂtures up to 120 °C in accorÂdance with DIN 4751
- Hot water sysÂtems with flow temÂperÂaÂtures of more than 110 °C in accorÂdance with DIN 4752
- Heat transÂfer sysÂtems with organic heat transÂfer media accordÂing to DIN 4754
- Oil firÂing sysÂtems accordÂing to DIN 4755
DisÂplay and operÂaÂtion
The two-line LCD disÂplay allows the limit value, the meaÂsured value and the comÂplete operÂaÂtion of the PMA TB45 to be disÂplayed. An LED and four other disÂplay eleÂments reliÂably indiÂcate the operÂatÂing staÂtus, operÂatÂing mode and error mesÂsages. The unit of the meaÂsured variÂable can be shown in the disÂplay and can also be defined on a cusÂtomer-speÂcific basis. Via the extended operÂatÂing level
any sigÂnals and paraÂmeÂters can be disÂplayed in the 2nd disÂplay line
InterÂface and engiÂneerÂing tool
SetÂtings can be made via the front panel as well as via the Blue-Port® front interÂface and the BlueÂConÂtrol® softÂware.
