below)
Speed (Hz) 10 200 2000 20000
Min. on/off (msec) 47.5 2.0 0.2 0.013
Analog output:
(Not available with 4-20 mA, Square Law
input type)
4-20 mA (or 0-20 mA)
Sinking, (NPN transistor), Open Collector
Compliance voltage: 3-24 VDC, non-inductive
Accuracy:
±
100 uA worst case
Update Rate: Follows ratemeter
Control Outputs:
SPDT Relays
Contact rating: 10 A 120/240 VAC or 28
VDC.
NPN Transistor Output
Open Collector sinks maximum of 100 mA from
10 VDC when active
Note: 10 VDC is provided at transistor outputs
through the relay coils. If current greater than
2 mA is drawn, the relay will remain energized.
Applying greater than 10 VDC may destroy the
unit. The transistor will sink 100 mA in the "ON"
state with relays installed.
