1. Function
NOTE
The SDM-CD16AC has 16 AC/DC relay control ports (see Figure 1). Each relay
port can be controlled by a datalogger or controlled manually with a manual
override toggle switch.
The toggle switch has three positions; "ON" and "OFF" for manual override,
and "AUTO" for datalogger control. In the "ON" position, the common
(COM) and normally open (NO) contacts are closed (see Figure 2). In the
"AUTO" position, the state of the relays are controlled by the datalogger
control ports.
The SDM-CD16AC is a synchronously addressed datalogger peripheral.
Three ports on the datalogger are used to address the SDM-CD16AC, then
clock out the desired state of each of the 16 control ports. Up to 16 SDMCD16ACs may be addressed, making it possible to control a maximum of 256
ports from the three datalogger ports.
In CRBasic, the SDMCD16AC instruction is used to control the SDMCD16AC. In Edlog, either I/O Instruction 104 (CR10(X), CR23X, 21X) or
Instruction 29 (CR7) is used.
Ensure that the datalogger contains the appropriate instruction
prior to system deployment. The SDM-CD16AC is not
compatible with our CR200-series, CR500, or CR510
dataloggers.

3. Power Considerations
The SDM-CD16AC power requirements are large compared to most CSI
products. For most applications an external power supply (see Figure 3) is
recommended to power the SDM-CD16AC.
For some applications it may be convenient to use the datalogger supply to
power the SDM-CD16AC (see Figure 3). For long-term applications, the lead
acid power supply available with CSI dataloggers should be used, allowing the
batteries to be float charged. It is not recommended that the datalogger
alkaline supply be used to power the SDM-CD16AC for long term
applications.
If the datalogger lead acid supply is used, the number of SDM-CD16AC's that
can be powered is limited by the 300 mA current sourcing capability of the
wall charger. With a continuous 6 mA current drain per SDM-CD16AC and
45 mA per active LED, a maximum of 6 LEDs may be powered by the
datalogger, after which, more current is drawn than can be sourced by the wall
charger. If this condition is maintained, it will ultimately lead to battery deep
discharge, requiring new batteries.
