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.

Interchangeable Output Modules can quickly be connected to the Smart Indicator and are automatically recognized. Dual relay output module has two changeover relays with a common wiper. Each relay can be set as high or low alarm independently. An isolated retransmission module provides 0 to 10 mA, 0 to 20 mA, or 4 to 20 mA output in active (source) or passive (sink) modes. The output can be any portion of the display. The Modbus® serial communication module allows communication with a PC for configuring or monitoring.
