to CHASSIS
32 V Transient suppressor across
VIN + to PSGND Meets ANSI/IEEE C37.90-
1978
Low Power Mode
ControlWave LP power consumption is highly
dependent on the actual application program and
whether or not you are using internal loop power to
field devices.
Typical power consumption range: 150 to 200 mA
@ 24 Vdc
Fixed Multifunction Input/Output Board
The Fixed Multifunction Input/Output Board (FMI/
OB) contains four I/O modules with pluggable termi-
nations and a PC-104 Interface for interconnection
of fixed and expansion I/O subsystems. The board
also provides for electrical isolation to field devices,
surge suppression, and LED indicators for Discrete
I/O, CPU, and communications functions. The four
I/O modules are fixed as follows:
16 Discrete Inputs
8 Discrete Outputs
4 High Speed Counters
8 Analog Inputs
Two on-board Field Power Supplies are provided:
one for DI and HSC operation and one for AI opera-
tion. The output voltages are electrically isolated
(500 VDC) and are regulated at 24V.
