 e SDM-CD16D increases the number of digital

outputs that can be controlled (i.e., set to 0 or 5 Vdc)

by a Campbell datalogger.  e SDM-CD16D is com-

monly used to drive normal logic level inputs. It can

also source some current; when an output is set HI,

a ‘boost’ circuit allows the SDM-CD16D to source a

current of up to 100 mA, which allows it to directly

control low voltage valves, relays, etc.

SDM-CD16D 16-Channel Digital Control Port Expansion Module

SDM-CD16S 16-Channel Solid State DC Relay Controller Module

 e SDM-CD16S is a 16-channel, solid-state relay

driver that can control devices that have a relatively

high-powered load such as solenoids, solenoid valves,

dc motors, stepper motors, lights, horns, heaters,

and fans. With a voltage range of up to 48 Vdc and

a maximum current output per channel of 2 A, the

SDM-CD16S can drive up to 100 W of power on each

channel. Separate inputs for power-to-outputs (48 Vdc

maximum) and power-to-SDM-CD16S logic (7 to

48 Vdc) allow the option of powering the logic from

the datalogger’s 12 V while switching a higher voltage.

SDM-CD16AC 16-Channel AC/DC Relay Controller

 e SDM-CD16AC has 16 switchable ac/dc relays

for control of ac or dc devices. Each port is logically

controlled by the datalogger; toggle switches provide

manual override capability. An LED indicates when

each port is active. Ports can be controlled individu-

ally or in groups. A 12 Vdc external power supply is

recommended.  e SDM-CD16AC is UL approved.

UL/CUL contact ratings:

DC devices: 5 A @ 30 Vdc, 0.3 A @ 110 Vdc•

AC devices: 5 A @ 125 Vac (1/10 hp), •

5 A @ 277 Vac (1/6 hp).
