STB55-5000-000 P.M.A STB 55 Temperature Limiter, 100 x 50mm Relay, 230 V ac Supply Voltage ON/OFF

P.M.A Temperature Controller_x000D_ 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._x000D_ Features and Benefits_x000D_ 1 SPDT relay for alarm output_x000D_ Basic error greater than 0,5%, ±2digits_x000D_ Clips onto top-hat DIN rail_x000D_ Convenient 4-key operation_x000D_ Input from Pt 100 in 3-wire connection, or dual thermocouples type J, K, N and S_x000D_ Memory function for error signalling_x000D_ Operator lock (password protection)_x000D_ Programmable temperature limit and switching hysteresis_x000D_ Response time 0,5 second_x000D_ Applications_x000D_ Thermal processes need to be monitored and the plant switched into a safe condition in case of a fault_x000D_ Certifications_x000D_ EN 14597_x000D_ EN 61508 SIL2_x000D_ IP20 rated
