SP/DTSS Surface measuring station

Description

SP/DTSS surface station for transmitting seismic data in the ARAMIS M/E system.

The device works with NSGA transmitters or SN/DTSS stations. The rack consists of: OCGA receiver modules, a ST/DTSS transmission control module, and a power supply module. One rack allows connection of up to 16 subordinate devices.

Functions:

collecting and forwarding data from subordinate devices to the ARAMIS M/E system,
providing digital data transmission and transmission error signaling,
providing intrinsically safe power supply.

The SP/DTSS station is an associated apparatus of Group I, Category M1. It operates in a non-hazardous (non-explosive) area and has intrinsically safe output circuits.
