Introducing The Usb-Ssr08; Compatible Ssr Modules - Measurement Computing USB-SSR08 User Manual

Introducing the USB-SSR08

The USB-SSR08 is a USB 2.0 full-speed device that provides the following features:
Mounting rack for eight solid state relay (SSR) modules (backplane is divided into two groups of four

modules each).
Onboard switch to configure the module type (input or output) for each module group.

The following configurations are supported (you cannot mix input and output modules within a group):
o Four input and four output modules
o
Eight input modules
o Eight output modules
Onboard switch to configure the control logic polarity (active high or low) for each module group.

Onboard switch to configure the power-up state for output modules.

Switch settings can be read back with software.

Independent LEDs at each module position to indicate the on/off status of each module.

Eight pairs of screw terminal banks for field wiring connections, with positive (+) and negative (-) relay

contacts brought out to the terminals.
USB out and power out connections support powering and controlling multiple MCC USB devices from

one external power source and one USB port in a daisy-chain configuration.
Rugged enclosure that can mount on a DIN rail or on a bench

The USB-SSR08 is powered by an external 9 V, 1 A regulated power supply that is shipped with the device.
The USB-SSR08 is fully compatible with both USB 1.1 and USB 2.0 ports. Revision F and later devices are
also compatible with USB 3.0 ports.

Compatible SSR modules

The USB-SSR08 has locations for eight solid state relay modules. The SSR modules use a standard color
scheme so you can quickly identify what module type is installed. Mounting screw threads are provided for you
to easily install the SSR modules.
MCC offers the following SSR modules that are compatible with the USB-SSR08:
SSR-IAC-05

SSR-IAC-05A

Details on these SSR modules are available at www.mccdaq.com/products/signal_conditioning.aspx.
Remove the USB-SSR08 from the enclosure to install SSR modules
Remove the USB-SSR08 from the enclosure to access the solid-state relay module mounting positions.
* Depending on your load requirements, daisy chained devices may require a separate power supply.
