P.M.A Temperature Controller


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.

Features and Benefits


1 SPDT relay for alarm output

Convenient 4-key operation
Input from Pt 100 in 3-wire connection, or dual thermocouples type J, K, N and S
Memory function for error signalling
Operator lock (password protection)
Programmable temperature limit and switching hysteresis
Response time 0,5 second

Applications


Thermal processes need to be monitored and the plant switched into a safe condition in case of a fault
