SP/T6 - 6-channel temperature protection and diagnostics module
Temperature control module SP/T6 is a 6-channel module which supports inputs for connection of thermocouples and resistant thermometers as well as 6 current outputs of slowly varying 4-20mA signal value DA-converter.
Four relay (RELAY) SP/T6 modules are programmed for special alarm set points for one or several channels.
