The RE12S from Sifam Tinsley is a universal PID controller in a compact 52×52 mm panel-mount form factor. It supports adaptive, auto, and self-tune PID as well as simple ON-OFF control, with a dual 4-digit LED display (white process value, green setpoint) and a capacitive touch keypad.

What input types does the universal input accept?

Thermocouples (J, K, T, R, S, C, E, B, N, L, U, W, Platinel II), RTD (PT100), and linear DC signals for voltage/current-based transmitters.

What can the Modbus RS-485 interface do?

Remote setpoint adjustment, reading process value (PV), reading and writing PID parameters, alarm status monitoring, and profile control — all accessible from a PLC, HMI, or SCADA system via Modbus RTU protocol.

What is the profile controller capable of?

Up to 128 ramp/soak steps, allowing the RE12S to execute complex temperature profiles for heat treatment, drying, and curing processes without an external PLC or setpoint programmer.

What output configurations are available?

Three configurable outputs — typically allocated as a control output (relay or SSR drive), an alarm output, and an analog retransmission output (0/4–20 mA) for recording or cascading to another controller. Alarm types include deviation high/low, absolute high/low, band, and sensor break.
