- Converts AC and DC to TTL logic signals using negative logic
- Features optical isolation and voltage turn-off load
- Fully encapsulated input and output modules for use with the SSR Series backplane
- Data Sheet
With the SSR Series, a modular approach to digital signal conditioning, you can mix and match signal types in one system. These SSR modules in conjunction with National Instruments DAQ boards can (1) sense AC and DC voltages from field devices and convert them to digital TTL signals, or (2) use TTL digital signals to control field devices and switch signals. Each SSR module is fully encapsulated and plugs into an 8, 16, 24, or 32-slot backplane, or a shielded carrier. Field signals connect to screw terminals on the backplane, making it easy to swap or replace modules. The SSR backplane even has status LEDs for each module, allowing you to visually verify digital signal levels. You can use input modules to monitor the state of a load or a sensor, such as a temperature switch or limit switch. You can use output modules to switch AC and DC loads, such as solenoids, motors, and lamps.
