The 2132i/2116i are compact high performance four digit units with large, bright green LEDs for measurement and display of temperature and other process variables in standard 1/32 and 1/16 DIN panel sizes. Both models include an optional alarm relay output and logic connection for either a second external alarm relay or alarm acknowledge input. Accurate stable measurement of temperature, pressure, level, flow and other process variables are provided by the 2408i, 1/4 DIN universal indicator. An optional second process value input allows the average, difference, minimum or maximum of two values to be displayed. The universal input employing patented Instant Accuracy&#153 technology accepts a wide range of two wire temperature sensors and process inputs. An optional external output module can be ordered to convert the logic output to a relay. An external precision resistor input adapter can accept 4-20mA process inputs.
