WRC-4 Relay Modules
|
|
|
|
|
The
WRC-4 series relay modules are isolated solid-state relay modules that
interface "ON/OFF" electrical signals to a computer. The modules
provide a 4kV isolation barrier between the field device and the computer.
The input modules convert ac or dc voltages to +5Vdc logic. The output
modules provide ac or dc switching levels in response to +5Vdc logic-level
commands.
The
WRC-4 package contains a status LED and replaceable fuse. All modules are
interchangeable with other industry standard I/O modules. |
