1.3.2 ELCOR plus , DATCOM plus
ELCORplus, DATCOMplus can be supplied in a single channel or dual channel design. Its
features can be largely customized by additional modules. The device can be operated either as
battery-powered or with external power supply. In devices equipped with an internal modem, the
modem is powered by a separate battery; alternately, it can be powered from an independent
external power supply. Extension modules are inserted into slots (SLOT 0 to SLOT 5) on the input
board.
a) Basic (minimum) configuration of the device:
- Single channel (dual channel) battery corrector
- Six-key keypad
- Graphic or multisegment display
- 1 x (2 pcs) digital pressure transducer EDT 96
- 1 x (2 pcs) digital temperature transducer EDT 101
- 1 x (2 x) pulse input for connecting the gas meter with the LF pulse output
- 3 x (2 x) digital input
- 4 x digital output (binary, or pulse, or analogue)
- Optical head communication
- 1 x corrector battery
b) The basic version can be extended by one of the following modules:
- 1 x interface module for gas meter with encoder (SLOT 0 position):
- NAMUR interface module for NAMUR encoder; or
- SCR interface module for SCR encoder; or
- Module for connection of HF pulse output of gas meter (module EXT1, EXT1/HF)
- module for connection of HF pulse output of gas meter and extension of digital
and analogue inputs (EXT1 module with auxiliary terminal board EXT1-T)
- 1 x communication interface or analogue input/output module (SLOT 1 position):
- Communication module RS232/RS485 for communication with the master system; or
- Analogue input module 4 - 20 mA (2 inputs); or
- Analogue output module 4 - 20 mA (2 outputs)
- 1 x communication interface or analogue input/output module (SLOT 2 position):
- Communication module RS232/RS485 for communication with the master system; or
- Analogue input module 4 - 20 mA (2 inputs); or
- Analogue output module 4 - 20 mA (2 outputs)
- 1 x PWR1 module for connecting an external IS power supply for the device (SLOT 3)
