The 16DI module provides 16 dry-contact (sensor not connected to any voltage including ground) inputs plus two high-speed counter inputs (range 0-32,767). Any of the 16 dry-contact inputs may be used as low-speed counters under application control. The module provides an isolated current so the open/closed state of the sensor may be determined. Each of the inputs are opto-isolated from the remaining circuitry on the module to provide maximum input surge immunity. All connections to the module are via plug-in screw terminals. Availability: Usually ships in 6-8 weeks.
