LT20DCV1 DIN Rail 4-20 mA and RS485 Transmitter by Laurel Electronics

-200.00 to +200.00 mV DC input, 4-20 mA or 0-10V analog output plus RS232 or RS485 I/O and dual relays

Model LT20DCV1 includes:

  • -200.00 to +200.00 mV DC input
  • 4-20 mA or 0-10V isolated analog output
  • Modbus or ASCII serial data output
  • Universal AC power, 85-264 Vac
  • Two 120 mA solid state relays

  • 35 mm DIN rail mounting

Model LT20DCV1 by Laurel Electronics is a -200.00 to +200.00 mV DC input, 4-20 mA or 0-10V analog output plus RS232 or RS485 I/O and dual relays DIN rail transmitter. Model is configured for Standard main board, Universal AC power, 85-264 Vac, and dual relays.

The Laureate Modbus or serial output, DC input transmitter provides six voltage input ranges and four current input ranges, all factory calibrated and jumper selectable. The 200.00 mV and 2.0000 V ranges provide a high input impedance of 1 Gohm to minimize the load on the voltage signal. A 5.000A range measures the IR drop across a built-in 10 mW current shunt. The transmitters can also easily be scaled in software for use with external shunts.

Three analog transmitter output settings are jumper selectable: 4-20 mA, 0-20 mA or 0-10V. All selections provide 16-bit (0.0015%) resolution of output span and 0.02% output accuracy. The output tracks the reading from -99,999 to +99,999 counts that would be transmitted digitally. For DC signals, this reading has a rated accuracy of ±0.01% of full scale input and can be scaled in software. Output isolation from signal and power grounds eliminates potential ground loop problems. The supply can drive 20 mA into a 500 ohm (or lower) load for 10V compliance, or 10V into a 5K ohm (or higher) load for 2 mA compliance.

Fast read rate at up to 50 or 60 conversions per second while integrating the signal over a full power line cycle is ideal for peak or valley capture and for real-time computer interface and control.

Standard features of Laureate transmitters include:

  • Analog transmitter output, 16-bit, user scalable and isolated. User selectable 4-20 mA, 0-20 mA or 0-10V levels.
  • Serial communications, isolated. User selectable RS232 or RS485, half or full duplex, Modbus or Laurel ASCII protocol.
  • Dual solid state relays for control or alarm, isolated. Rated 120 mA at 130 Vac or 170 Vdc.
  • Transducer excitation output, isolated. User selectable 5V@100 mA, 10V@120 mA or 24V@50 mA.
  • Universal AC power supply for 85-264 Vac.
