AST121N - RTD Input Temperature Signal Trip Amplifier

The AST121N is our Thermocouple Temperature Signal Trip Amplifier with two trip output set points suitable for SIL 1, 2 & 3 applications Input is our 2, 3 or 4 wire resistance temperature sensor. Third wire compensation is standard to overcome lead resistance variation. Trip output is a double pole changeover contacts, rated at 250VAC, 2A, 100VA resistive Environmental Condition Performance Mounting/Dimensions Environmental Condition Storage Temperature: -40?C to +70?COperating Ambient: -15?C to +55?CRelative Humidity: 5% to 95% RH Performance Trip settability: ?1% Trip repeatability: ?0.1%Response time: <400mS Mounting/Dimensions Enclosure: 22.5w x 95h x 110d mmMounting: Din Rail (TS35)
