Subsea Converter Unit

Description

The Subsea Converter Unit (part number 105879) is a standalone subsea unit for converting analog and/or digital signals to a communication link. The Subsea Converter Unit communicates over RS232 and RS485 and is depth rated to 3000 m.

The digital input counter frequency is 0–200 kHz and the analog input resolution is 16 bit (65535). The Subsea Converter Unit runs on a supply voltage of 21.6–26.4 VDC with a power consumption of ~1 W. Operating temperature (ambient) is −20 to +50 °C and storage temperature is −40 to +70 °C.

The Subsea Converter Unit measures 132 × Ø60 mm and weighs ~1 kg. It has two connectors: J1 communication interface (0 V, 24 VDC, RS485+, RS485−, RS232 TX, RS232 RX, RS232 GND) and J2 sensor interface (0 V, 24 VDC, two 4–20 mA inputs and two digital inputs).
