DM3410 - RTD / Thermocouple Input Panel Meter Data Sheet

INTELLIGENT DIGITAL INDICATORS DM3400 SERIES DM3410 (Pt100, T/C) DM3420 (CURRENT, VOLTAGE) BUILT IN 24V PSU FOR TRANSMITTER EXCITATION (DM3420) IP65 FRONT PANEL SEALING PLUG & PLAY POD OPTIONS FOR RELAY / CURRENT OUTPUT INTRODUCTION The DM3400 series uses proven technology to accept all commonly used temperature or process inputs. Engineering units are displayed on a high efficiency Red LED display that provides excellent readability. The DM3410 takes inputs directly from Pt100 or Thermocouple sensors for Temperature indication. The DM3420 current and voltage for Process indication. The DM3420 also has a transmitter power supply built in for excitation of 2 wire (4 to 20) mA process transmitters. The highly innovative case design enables output option ‘Pods’ to be easily installed without the need for dismantling or re-calibration. ‘Plug and Play’ Pods are available covering: • POD-02 2 x Relay outputs • POD-03 Active or Passive Isolated re-transmission ((0 to 10) mA, (0 to 20) mA, (4 to 20) mA) A maximum of 2 POD outputs can be fitted to each indicator. The indicator provides a transmitter power supply on the output to excite the POD-03 current retransmission. Output combinations are • Dual Relay Pod and Retransmission Pod • Dual Relay Pod and Dual Relay Pod • Dual Relay Pod • Retransmission Pod The front panel is sealed to IP65 and the case has a moulded in rubber gasket enabling it to seal to the panel maintaining the IP65 rating, ideal for installing it in ‘dusty’ areas or where low pressure jets of water are used to clean down equipment. The unit is programmed using the three push buttons on the front panel where the user is guided through the configuration process.
