Application
The micro-processed PSG Controller ST 49 serves for temperature control of the gas sampling probes PSG Basic Probe and PSG Plus Probe as well as for the PSG Basic Heated Sampling Tube and the heated sample lines PSG Extruded, PSG Plus Extruded, PSG Basic Flex and PSG Plus Extruded Hybrid. Also, for heating sleeves and heated wall ducts the controller is applicable.
Technology
The PSG Controller ST 49 is a PID-controller that will be parameterized in different levels for the individual needs of the respective devices. The controller is available for 115VAC, 230VAC and 400V 3ph. The solid-state relay is mounted on a heat sink and has 25A switching capacity for 115/230VAC and 50A for 400V 3ph. Controller and relay are suitable for DIN rail or wall mounting.
Functions
Beside resistance sensors and semiconductor thermocouples the multi-sensor input of the PSG Controller ST 49 can equally process 0…10V and/or 4…20mA. The PID and/or thermostat control can be activated by parameter setting. Different outputs are available, such as two relay contacts, a voltage output for the solid-state relay and an analogue output. A temperature limiter function with alarm message is also available. Red LEDs indicate the status of the output relays. The set-points and parameters determining the process are adjusted by a 4-field foil keyboard.
