The YTA110 supports either BRAIN or HART communication YTA110 in it standard configuration is certified by T V as complying with SIL2 for safety requirement. FEATURESHigh performanceMicroprocesser-based sensing technology ensures long-term accuracy and high reliabilityDual-compartment housing realizes high resistance capability to harsh environments, and YTA110 has SIL2 capability for safety of sensor inputsThe type of sensor input is user-selectable from thermocouples (T/C), RTDs, ohms, or DC communicationBRAIN or HART communication protocol is available.
