Binary input/output module (IOM)

Introduction
The binary input/output module is used when only a few input and output channels are
needed. The ten standard output channels are used for trip output or any signaling
purpose. The two high speed signal output channels are used for applications where
short operating time is essential. Eight optically isolated binary inputs cater for
required binary input information.
Design
The binary input/output module is available in two basic versions, one with
unprotected contacts and one with MOV (Metal Oxide Varistor) protected contacts.
Inputs are designed to allow oxide burn-off from connected contacts, and increase the
disturbance immunity during normal protection trip times. This is achieved with a high
peak inrush current while having a low steady-state current, see figure 312. Inputs are
debounced by software.
Well defined input high and input low voltages ensures normal operation at battery
supply ground faults, see figure 311.
The voltage level of the inputs is selected when ordering. Alternative connectors of
Ring lug or Compression type can be ordered.
I/O events are time stamped locally on each module for minimum time deviance and
stored by the event recorder if present.
The binary input/output module version with MOV protected contacts can for example
be used in applications where breaking high inductive load would cause excessive wear
of the contacts.
The test voltage across open contact is lower for this version of the
binary input/output module.
