The Series 4B 1/4 DIN Temperature/Process Controller
is designed to accept thermocouple, RTD, current or voltage input and
provide dual outputs for control. Available outputs include relay/relay,
voltage pulse/relay, current/relay, or linear voltage/relay.
The units can be programmed for ON/OFF, PID, auto-tuning, or manual
tuning control methods. The PID control is supported by 64 ramp/soak
actions. The Series 4B also includes two additional alarm outputs. The
second relay output can be reconfigured as a third alarm output. The
alarm type can be selected from 13 different preprogrammed alarm
functions. The controller features dual LED displays for local
indication of process and setpoint values.
