Universal Input (6 T/C, RTD, mV, V, mA)| The Compact Model 7SF is a dual display general purpose 1/16 DIN PID controller with autotuning and 3 configurable outputs. OP1 (logic or relay) and OP2 (relay) are for heating + alarm or heating + cooling (air, oil or water) control and OP3 (relay) is an optional second alarm. Alarms can be process, band or deviation type, direct or reverse, with masking and automatic or manual reset. A logic input is fitted as standard, allowing remote selection of an auxiliary setpoint. The externally selected transfer between SP1 and SP2 can be a step or a ramp with two configurable rates of change (ramp | up/ramp down). Bumpless Auto/Manual control can be selected from the front panel. Detection of an out of range or sensor break forces the output to a safe value (Auto Compª sensor break). The 7SF is available with optically isolated RS-485 communications in three protocols for use with supervisory systems. This easy to use instrument comes from the factory with its inputs already calibrated and it can be configured either from the front panel or via the communications port. NEMA 4X sealing allows it to be used in washdown or dust conditions. | ||
