Art.Nr.: TB225Produktbeschreibung
in accordance with DIN EN 14597
general information:
- for use as a temperature limiter or monitor
- certified according to EN 14597, optional EN 61508 (SIL2)
- configurable operating / configuration lock
- universal signal input
- 2 relay changers + analog output
- intuitive operation: Illuminated graphic display
- display colour change in the event of an alarm "white / red"
- safe 3-way galvanic isolation
- wide range power supply 18...230 V AC/DC
brief information:
The connected temperature signal is evaluated and monitored. If the permissible threshold is reached or an error occurs within the permissible temperature range, the TB225 switches off immediately. The additional relay output of the TB225 enables the
function of a preliminary alarm with an independent threshold. The following operating modes are possible through configuration:
function of a preliminary alarm with an independent threshold. The following operating modes are possible through configuration:
temperature limiter:
Maximum or minimum monitoring with catch, manual resetting after fault elimination via the front keys or an external switch / voltage signal. Operating methods in accordance with EN14597: 2012: type 2B, 2H, 2V
temperature monitor:
Maximum or minimum monitoring without catch, automatic resetting
on return to the permissible range. Operating methods in accordance with EN14597: 2012: type 2B
Maximum or minimum monitoring without catch, automatic resetting
on return to the permissible range. Operating methods in accordance with EN14597: 2012: type 2B
