10 bit A/D
3 digital outputs, relay contact rated at 1 A max. @ 24 Vac/Vdc. Configured
normally open.
1 analog output, 0–10 Vdc (5 mA max). The controlled device must have a
minimum of 2000 Ohms resistance measured from its input to ground and
must share the same ground as the controller.
8 bit D/A
Brushless DC motor, torque 35 inch-pounds (4 Nm), runtime 205 seconds for
90 degree travel during control, or 25 seconds in high-speed test and balance
mode
10-year Lithium CR2032 battery provides a minimum of 10,000 hours of data
retention during power outages
Incoming power and network connections are protected by non-replaceable
internal solid-state polyswitches that reset themselves when the condition that
causes a fault returns to normal. The power, network, input, and output
connections are also protected against voltage transient and surge events.
You attach a BT485 (not included) to a controller at the beginning and end of
a network segment to add bias and to terminate a network segment.
