Series SI Smart Indicator is fully programmable and accepts all commonly used temperature or process inputs. Programming is via the front panel keys following a logical menu structure which can be set to "short" (default) for common usage features or "full" where the full range of programmable features are available. The indicator can also be programmed via a PC using the RS485 Modbus® communication module. Password protection can be enabled to prevent any unauthorized setting changes.

The Series SI features a 4-digit red LED with selectable resolution. The display can be set to indicate a fixed number of decimal places or auto scale for maximum resolution. Optional interchangeable modules for relay, 4 to 20 mA retransmission, or Modbus® RS485 serial communication output are easily installed without the need for dismantling or recalibration.

Model SI-13 Smart Indicator is designed to accept 2 or 3-wire Pt100Ω RTD or Types J, K, T, R, S, E, F, N, or custom thermocouple inputs. Temperature measurements can be displayed in selectable °F or °C. High/low scale burnout, input filtering or smoothing, and offset can be defined by the user. Select Model SI-23 Smart Indicator for process signal input. The indicator has an internal power supply to provide excitation to field transmitters. Parameters such as input type, range, engineering units, resolution, burnout condition, and filter time constant can be easily programmed.
