New high-density discrete I/O for the Series 90-70 are half-width modules that can be used in either a standard Series 90-70 rack or an integrator rack. When the modules are placed in the integrator rack, the I/O capacity is doubled. 

GE Fanuc now offers high-density discrete I/O VME modules that can be easily integrated into Series 90-70 controllers. With up to 64 discrete I/O on a module, cost can be reduced by as much as 50%.

The discrete modules provide high-speed data to the controller over the VME backplane. The 4VDC input module can also be configured to support Sequence-of-Events (SOE) and can store up to 3,000 events. There are two relay output modules and a 24VDC output module to chose from to satisfy a wide range of applications.

Application Benefits

• The high-density analog modules enable panel space to be cut 50% to 75% or more. Traditional discrete modules for the Series 90-70 had a maximum of 32 points per module versus 64 points now available.

• The built-in test feature on many of the modules provides quick diagnostics and reduces downtime. The built-in test checks the circuitry of the module and narrows down the point of failure.

• High-density modules with cable connections can be terminated easily using the DIN Rail Transition Module, which provides a high-density screw terminal block with easy universal mounting.

Product Features

• 24VDC Input Module

• 64 optically isolated inputs.

• Sequence-of-Event (SOE) option allows each change-of-state to be time-tagged in SOE buffer. The SOE buffer collects the channel ID and the time (time tag register) in which the state changed. This buffer can contain 3,000 events.

•  24VDC Output Module

• 64 outputs at 500 mAmp continuous

• Output transient protected

• Wired for Sink or Source outputs

• Relay O utput Module

• 64 or 32 points @ 2.0 amps current rating per point

• Protection from relays changing during power up/down

• Form C Single-Pole-Double-Through contacts

• Compatibility

• The high-density modules are compatible with all Series 90-70 CPUs and racks. Due to increased power consumption on the 5VDC supply, a high-capacity power supply may be required.
