 e SDM-CVO4 outputs either a voltage signal

(0 to 10 V) or a current signal (0 to 20 mA). Typical

applications include driving remote current loop dis-

play units, retransmitting measured values to systems

that have current or voltage inputs, sending control

signals to valve controllers, and providing excitation

voltages or currents to sensors that cannot be excited

directly by a datalogger.

 e SDM-CD8S controls DC devices that have a mod-

erate current load, such as solenoids, solenoid valves,

DC motors, stepper motors, lights, horns, heaters,

and fans.  e SDM-CD8S is targeted for applications

requiring only a few control ports, where a larger,

high-powered relay module such as the SDM-CD16S

is not necessary.  e voltage range for this device is 8

to 26 Vdc. It can deliver up to 1 A per channel with a

maximum of 6 A total for all channels.

SDM-CD8S 8-Channel Solid-State DC Controller

SDM-CVO4 Four-Channel Current and Voltage Output Module

SDM-INT8 Eight-Channel Interval Timer

Each SDM-INT8 input channel is programmed to

detect voltage transitions, then output any combina-

tion of period, pulse width, frequency, counts, and

time intervals. Additional output options include

average over the scan interval, average over a speci-

 ed interval, or output all events. Events are measured

with 1 µs resolution, making comparison of inter

channel events accurate to ±1 µs.
