The V408 is an 1/8 DIN, universal, 5 digit indicator with four alarms, two digital inputs and one SPDT relay output. Available with a green or red display, it accepts temperature inputs from J, K, T, L, N, R, S, B, C and Platinel II type thermocouples and three-wire Platinum 100 Ohm (Pt100) RTDs. Process variables such as 4-20mA, 1-5V and 0-10V as well as strain gauge bridge inputs can also be measured. Other thermocouple types or high accuracy 20 to 80 point custom linearization curves can be configured at the factory. Square root extraction or eight-point curve linearization can be user defined in the field. A second process input is available to accept remote setpoints and compare signals such as the average or difference, or selecting minimum or maximum readings.

Four programmable setpoint alarms can be field configured as rate of change, deviation high or low, non-latching and high or low or new, latching. The new alarm indicates the situation when a latched alarm has not been acknowledged and the measured value crosses the setpoint trip level a second time. The deviation alarm enables the user to reference alarm setpoints relative to a remote (main) setpoint from a controller. This remote setpoint would be a DC signal input to the optional 2nd process input module. Alarm hysterisis (deadband) can be configured from 1 to 9999 process variable units. Each alarm has a programmable delay up to 999.9 seconds.

The alarms can be linked to either the one standard relay output or up to three optional relay or digital output modules. These alarms can be configured in combination (e.g., one or all four alarms linked to one or all relays) and they will operate in fail-safe (i.e., normally energized) or non-fail-safe modes. Additionally, the display can be configured for password protection, limiting access to any or all functions. An alarm blocking function is also configurable to prevent alarm tripping during process start-up. Two digital input channels are provided to accept alarm acknowl- edgment (e.g., remote pushbutton). These two digital inputs or the optional triple-digital input modules can also be used for remote setpoint select, alarm acknowledge, process input select, bridge zero and span calibration and tare. Other functions include indicator control such as selecting full menu access, disabling the keypad lockout or simulating keypad functions.

The V408 indicator housing maintains a NEMA 4 (IP54) front panel seal and can be removed or unplugged from the front, without disconnecting any wiring. By disengaging the front panel clips the entire indicator and electronics can be quickly pulled from the panel.

Thermocouples, three-wire RTDs, bridge, voltage and mV signals can be accepted directly into the indicator. Current signals such as 4-20mA are input using the 2.49 Ohm shunt resistor included with the indicator and mounting hardware. The five-digit display (99999) is available in green or red and can be field configured to match the input signal range to the preferred engineering units. Offsets and two point slope adjustments are fully programmable to compensate for sensor variances.

The V408 is an excellent solution for temperature, pressure, level, flow and other process variable measurements. The modular design was developed to allow it to be optimally configured for most indication, alarm and data acquisition applications.

The wide variety of option modules and programming functions make the V408 a valuable plant-wide indication solution. For example, the secondary input enables functions such as differen- tial measurement and summing with the use of K values for signal scaling. This function is useful in monitoring the mixing of products or raw materials. The deviation alarm can be used to ensure that a product is not diluted or spoiled by significant process excursions beyond the setpoint.

The field configurable V408 is an ideal standardized solution for a variety of temperature measurement and on-off control appli- cations. For example, it can be used to control the heating and cooling elements in an oven or environmental control system using two setpoints for the high and low temperature limits. Similarly, a 4-20mA or bridge pressure signal can be monitored and the setpoints can be used to control or alarm the gas pressure or liquid levels in a tank. Weight, flow, pressure, temperature, speed, position and rate are just some of the process variables that can be accurately displayed and monitored with this flexible and effective indicator.
