2.Specification
44 PROSEC T2N
Item
PI21
(EX10*MP121)
Input Voltage A, B, M 12V ± 10% / -5% (12V setting), 5V +10% / -5% (5V setting)
Range EXT 12~24Vdc +10% -15%
Minimum ON A, B, M 9V (12V setting), 3.5V (5V setting)
Voltage EXT 9.6V
Maximum OFF A, B, M 2V (12V setting), 1V (5V setting)
Voltage EXT 3.6V
A, B, M 12V-7.5mA (12V setting), 5V-10mA (5V setting)
Input Current
EXT 24V-10mA, 12V-5mA
Number of Input Points 1 point phase A, B, M and ETX
Pulse Counting Speed 100Kpps (max) (pulse-width 4 µ sec or more)
Counter Configuration 24-bit binary
Quadrature Phase A, B (90 degree phase shift), up/down
Pulse Input Mode
Up/Down Phase A: count up / phase B: count down
Normal Counter clears at simultaneous ON timing of phase M and
EXT input (edge), always executes count apart from this.
Counter Operation
Mode
Hold Executes count only when both phase M and EXT input are ON,
count stops when either is OFF (Count value maintained).
(Counter clear is at the same timing as the Normal Mode).
External (EXT) Input Operation Counter clears at simultaneous ON timing of phase M and
EXT input (edge)
External (EXT) Input Delay ON-OFF, OFF-ON each 5mS or less
Withstand Voltage 1500Vac / 1 minute (but except between each of the A, B, M
phases)
Current Consumption 80mA (5Vdc) or less
Weight Approx. 200g
