SECTION 6.0, ENHANCED REMOTE PANEL W/MULTI I/O MODULE
6.3.2.9 Multi I/O Board (Hardware)
The Multi I/O Board is a peripheral hardware interface. It communicates with the
other devices in the system via a network interface. It gathers information from
the TIE(s) and the Enhanced Remote Display via the network. It processes this
information together with its digital inputs and site specific configuration to
control its outputs.
The Multi I/O is capable of driving eight digital outputs (dry relay contacts) and
four analog outputs. It can read up to eight digital inputs. The digital inputs are
jumper configurable to be either dry contacts or 0 – 5 VDC signals. Dry contacts
are standard.
The analog outputs are jumper configurable to be 4 – 20 mA, 0 – 20 mA, or 0 –
24 mA current loop signals. (0 – 20 mA) is the standard jumper setting, though
the standard current output range is 4mA to 20mA. The standard jumper setting
allows values less than 4mA to be transferred to a data collection device. This
allows the 4mA level to function as a “live zero”. Test points are provided for
measuring output current. See Jumper and Test Point Tables 6-4A and 6-4B.
