Process Indicators

Model 405 is a micro-controller based alarm indicator, designed to accept multiple input types and two programmable set points with individual relays. Model 405 accepts 18 different types of inputs (all industry standard input types) which are field configurable. Variety of field inputs facilitates plant operator to use this model in any application. The unit is easy to operate and editing is user friendly. It has mainly three operating modes viz. configuration mode, program mode and calibration mode. CJC compensation for thermocouple input is done through software for higher accuracy. Provision for range setting is provided to restrict usage band for process safety. Model 405 is equipped with transmitter power supply, two relays, field selectable retransmission output and serial communication RS485 as standard, making this model a benchmark product in the international market. Retransmission output is field configurable which means output signal can be changed as desired from various options available. Importantly this retransmission output is isolated from other input/ output and internal circuit. Model 405 uses SMPS power supply to cover wide range of power supply from 90 to 270 VAC at 50 Hz. This model can also be used as single point RTU, using its serial communication data transfer capability through RS485 on MODBUS protocol. Model 405 is packaged in 96x48x248 mm metal enclosure (panel mounted) with front facial and enclosure rated for general purpose. Model 405 has a powerful watchdog circuit with close monitoring of software loop that ensures the proper instrument operation in case of power spikes that are very common in industrial environment.
