Features

• PMA TB 45 Temperature Limiter. The TB 45 temperature limiter is int***ed for precise, cost-effective signal monitoring ; limiting tasks. The TB 45 can be ***d for heating and refrigeration processes. It is suitable for all thermocouple types and resistance type sensors. It is particularly designed for *** in: all applications where an over or under temperature fault condition could present fire hazard or other hazard, heating system in buildings to DIN EN 12828, large hot-water boilers to DIN EN 12953-6, thermal transfer plants with organic heat transfer media to DIN 4754, oil-fired installations to DIN 4755 and limit signalling function for any type of input signal. Compact solution for distributed automation Display and operating functions 2 universal inputs for TC, RTD, R, U, I, O2 Universal output, relays / optocoupler outputs Front interface and BlueControl®-software RS 485 interface Compact design, only 22.5 mm (0.87 ) wide - saves space in the control cabinet Clips onto top-hat DIN rail Plug-in screw terminals or spring-clamp connectors - simple connection Dual-line LC display with additional display elements - process values always in view Convenient 3-key operation Direct communication between mounted controllers, fieldbus connections via bus coupler - simple integration into PLC/PC Universal input- also reduces stock keeping Second analogue input as universal input (optional) Universal high-resolution output as combined voltage/current output Two output relays or optocoupler outputs Fast 100 ms response - also suitable for fast signals
