Series 4B 1/4 DIN Temperature/Process Controller

Dual Control Output, RS-485 Communication, Auto-Tuning

Be the first to review this product

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.

Product Applications

Control temperature for boilers, damper control based on temperature or pressure.
Hot plates / melt pots
Packaging equipment
Environmental chambers
Medical equipment
Food service equipment
