1.5 Device and principle of operation
1.5.1 EMI-SSD-1M is able to connect 8 gas detectors simultaneously via «current loop» ana-
logue interface and «Bell 202» («HART» protocol) digital interface or 32 gas detectors via the RS-485
interface («Modbus RTU» protocol). In total up to 40 gas detectors can be connected to the device.
1.5.2 Data may be transferred to a higher level system via «RS-485» interface («Modbus
RTU» protocol), via wireless communication standards «LoRa» и «Bluetooth».
1.5.3 Data and events are archived on external SD card..
1.5.4 External circuits switching is carried out by 3 relays, shifting can be tuned.
1.5.5 EMI-SSD-1M channels tuning and configuration is carried out in control unit menu by
built-in key-pad and OLED-display, as well as by «Bluetooth».
1.5.6 Battery CR2032 for internal clock continuous operation is installed in EMI-SSD-1M.
1.5.7 Latches for fixing the device on a DIN rail are on the rear cover.
1.5.8 Indication alarm and control elements are on the upper front surface:
- OLED-display allows visually track changes in the values of variables from connected sen-
sors, and display a custom menu.
- two LED indicators:
a) «Operation»(green) –indicates that device is turned on;
b) «Failure»(red) –lights up in case of set threshold exceeding or connected detectors fail-
ure.
- piezoelectric radiator makes sound in case of set threshold exceeding or connect-
ed detectors failure.

- 8 control and menu navigation buttons:
- turn on/turn off/reload;
- up;
- down;
- left;
- right;
- confirmation (main mode –cannel information request);
- cancel/back (main mode –menu request);
- emergency mute (handshaking).
On the lower front surface there are EMI-SSD-1M detachable joints (terminal blocks), the
purpose of which is described in Table A1 of Appendix A. Actuators, sensors, communication lines
and power supply are connected to these joints. Split design of the terminal blocks allows to perform
hot-swapping.
SD-card slot and antenna LоRa connector are located on the upper side surface of EMI-SSD-
1M in accordance with Figure A1 of Appendix A.
1.6 Marking and sealing
1.6.1 EMI-SSD-1M marking must contain:
- name EMI-SSD-1M;
- manufacturer trademark;
- electrical terminals and external connections identification;
- light indication;
- supply voltage and power consumption value;
- IP degree of protection;
- factory serial number;
- manufacture year.
