Overview
OV3. Commonly Used Peripherals
DEPICTION DEVICE DESCRIPTION FUNCTION
SDM-AO4
Four Channel
Analog Out Independent CAOs updated by the logger.
Max current that can be sourced is 1 mA
SDM-CAN CANBus interface
CANBus data can be stored and synchronized
with measurements made by the logger.
SDM-CD16AC
16 Channel
AC/DC Controller
16 relays to control power to up to 16 external
devices. Max. 5 A @ 30 Vdc, 0.3 A @ 110 Vdc,
5 A @ 125 Vac, or 5A @ 277 Vac.
16 Channel Digital
16 Digital Outputs that can be set to 0 or 5 Volts
SDM-SIO4
4 Channel Serial
Input/Output
Four configurable serial RS232 ports that
communicate with intelligent sensors, display
boards, printers, satellite links, etc.
SDM-SW8A
8 Channel
Switch Closure
8 Channel pulse count module that can calculate
state, duty cycle, or counts.
Maximum input frequency: 100 Hz
AM25T
25 Channel
Multiplexer for
Thermocouples Solid state multiplexer, with a PRT, for measuring
thermocouple outputs. Can also be used to
multiplex voltages (cannot be used for currents).
AM16/32
16 Bank (4 Wires) or
32 Bank (2 wires)
Multiplexer Mechanical relay multiplexer that can be configured
as 16 banks of 4 lines or as 32 banks of 2 lines.
Commonly used for bridge measurements.
GPS16-HVS
Geographical
Position
Reciever Consists of a receiver and an integrated antenna.
Receives signals from GPS satellites for calculating
positionand velocity.
TIMS
Terminal
Input
Modules Molded components that supply completion
resistors for resistive bridge measurements, or, act
as voltage dividers or current shunts.
SDM-CD16D
Control Port Module
Can source up to 100mA, allowing direct control
of low voltage valves, relays, etc.
SDM-CVO4
4 Channel Current
or Voltage Output
Module Independently program each channel to output:
0 to 10 Vdc (2.5 mV resolution) or
0 to 20 mA (5 micro-Amp resolution).
SDM-INT8
8 Channel Timer
Pulse Counter
The INT8 calculates period, pulse width, frequency,
counts, or time interval with a 1 microsec
resolution.
Maximum time interval of 16.7 seconds.
