The FBM238 24DI/8DO Module provides twenty-four digital inputs with eight digital output channels. Associated Termination Assemblies (TAs) and Termination Assembly Adapters (TAAs) provide for discrete nominal inputs of 30 V DC, 60 V DC, 120 V AC/125 V DC or 240 V AC and nominal outputs of 60 V DC, 120 V AC/125 V DC or 240 V AC. The module performs signal conversion required to interface the electrical input signals from the field sensors to the Module Fieldbus.
Depending on the type of I/O signal required, the Tas or TAAs support current limiting devices, high voltage attenuation circuits, optical isolation and external power source connections.
FEATURES
- Twenty-four digital input channels, used for either contact sensing, or DC voltage monitoring
- Eight digital output channels, used for either DC output switching with an external source (e.g. to PSS 31H-2S238 control powering of various external loads), or DC output switching with an internal source only (e.g. to power external solid state relays or other similar devices)
- Rugged design suitable for enclosure in Class G3 (harsh) environments
- Supports discrete input signals at voltages of:
• 30 V DC/60 V DC
• 120 V AC/125 V DC
• 240 V AC
- Supports output switching at voltages of:
• 60 V DC
• 120 V AC/125 V DC
• 240 V AC
