The P.M.A STB55 series temperature controller has a supply voltage rating of 230VAC. This high precision controller has a width of 50mm and a height of 100mm. If the permissible temperature limit is reached or if a fault occurs in the monitoring equipment within the permissible temperature range (sensor break or short circuit, failure of a component within the device, fault in the software, failure or impermissible value of the supply voltage, etc.) the STB 55 switches off immediately. When the alarm contact is activated, the ALARM LED flashes in the front panel and the background lighting of the display lights up and the cause of the alarm appears in the display in a plain text. In addition, a 24VDC signal for external alarm signalling is available.
