Yokogawa 202 Field Mounting Rate Totalizer - Manual (Page 27)

Versions 23
Specification for Alarm Outputs
Maximum Current (sink): 200mA.
Maximum Voltage: 30Vdc.
Saturation Voltage: 0.8Vdc across outputs when in the "on" state.
Isolation: Both outputs are separately isolated.
Pulse Frequency: 500Hz maximum.
Pulse Duration: 1ms if CAL0 = 2 (unscaled pulse output).
If CAL0 = 1 (scaled pulse output) the duration of
the pulse automatically adjusts to the output
frequency:
a.
1ms if output > 50Hz.
b. 10ms if output = 5...50Hz.
c.
100ms if output < 5Hz.
