ABET 2G Starter Interface - Latched

This base unit may be used to support two test stations with 8 Inputs and 15 Output each or a single test station with 16 Inputs and 30 Outputs. Each half is independently fused, with software controlled safety relays to shut off the 28 V DC when not actively controlled.

Output drivers are more robust with higher current limits than previous units. This unit features latched inputs to filter and de-bounce animal responses. An Input response is only recognized when the transition from not activated to activated is made. 

For a second response to be recognized the the input must transition from activated to not activated and back to activated.  This type of input will not measure the duration of a single input.  Dwell or hold times can only be measured with two inputs typically defined as Normally Open (NO) and Normally Closed (NC).  Add Model 81502 Expansion Interface to support additional modules.  Order Model 81501-NL with non-latched inputs if required.
