The SDM-CD16S is a 16-channel, solid-state relay driver that was
originally developed for our trace-gas analysis (TGA) systems. It 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 26 Vdc and a maximum current output per channel
of 2 A, this module can drive up to 50 W of power on each
channel.
Features
The SDM-CD16S has 16 dc voltage outputs that can be switched on and off manually or under datalogger control. Separate inputs for the power to the outputs (48 Vdc max) and the power to SDM-CD16 logic (7 – 48 Vdc) allow the option of powering the logic from the datalogger 12 V while switching a higher voltage. LEDs allow a visual indicator of active outputs.
The outputs can be controlled by a datalogger or controlled manually with a manual override toggle switch and individual rocker switches for each of the outputs.
