Digital Input Surge Protection

Digital Input Lighting Protection

surge protection

Overview

This module is used mainly for Digital Input Lightning protection. No isolation is available on this module but the SSE MAESTRO M2000 or RTU12 and other DIN module have optical isolation.

The module is supplied by 12V that is supplied as common to 8 switching points on the plant. The module is ribbon connected to the SSE MAESTRO M2000 or RTU12.

Galvanic Isolation with Surge Protection

Additional protection of the Analogue inputs

surge protection

Overview

This unit is for additional protection of the Analogue inputs to the SSE MAESTRO M2000 or RTU12 and other I/O modules. This gives comprehensive Galvanic Isolation as well as lightning protection for harsh environments.

The Isolation is very handy in cases where self powered instrumentation is used or in typically sub-stations where earth differences and huge currents are flowing.

FEATURES

Voltage & mA

  • Maximum I/O Voltage: 30VDC.
  • Typically used for isolation of 4 – 20mA signals. Can not handle signals smaller than 4mA.
Physical Dimension
  • Length           : 135mm (for 8 channel)
  • Width             : 42mm
  • Height            : 80mm
Connection Sockets
  • 14-Way Ribbon to the Meastro CPU or I/O Modules.
  • 2 x 8 way screw pluggable termination connectors to field.
  • 2-Way Power supply 12V+, Ground
Channel (IO) Options available
  • Three Channels. (SSE-BBSI3C)
  • Four Channels. (SSE-BBSI4C)
  • Eight Channels. (SSE-BBSI8C)

Protection

  • 2.5kV Galvanic Isolation
  • 10kA Surge protection.

Ordering Information

  • Three Channels: SSE-BBSI3C
  • Four Channels: SSE-BBSI4C
  • Eight Channels: SSE-BBSI8C
