Specifications

Applicable PLC	FX5U, FX5UC, FX3U (V2.20 and later), FX3UC (V2.20 or later) [Connecting to the FX5U, FX5UC CPU module] FX5-CNV-BUS or FX5-CNV-BUSC is required to connect to the FX5U/FX5UC CPU module. Select one of the modules according to the system configuration. [Connecting to the connector-type PLC] The FX2NC-CNV-IF or FX3UC-1PS-5V is required to connect the FX3UC.
Number of occupied I/O points	8 point (Count either the input or output points of the PLC.)
Mass (weight)	0.2 kg
Range	When 32-bit is specified: -2,147,483,648 to +2,147,483,647 When 16-bit is specified: 0 to 65,535 (upper limit is set up by BFM #3, #2, #43, #42.)
Counter mode	Automatic UP/DOWN (However, when on 1-phase 1-input mode, UP/DOWN is determined by the following.) [Hardware UP/DOWN] Up/down count is decided by OFF/ON of the A-phase input terminal. [Software UP/DOWN] Up/down count is decided by the current value (K0/K1) of BFM #1, #41.
LED	φA, φB, DIS, PRE, YH1, YH2, POWER, UP, DOWN
No. of input channels	2 ch
Input type	Open collector, differential line driver (The differential line driver output type encoder is connected to 5 V terminal.)
Input voltage	5 V DC, 12 V DC, or 24 V DC can be selected with the connection terminal.
Max. response frequency: 1-phase 1-input	200 kHz or less
Max. response frequency: 1-phase 2-input	200 kHz or less
Max. response frequency: 2-phase input	200 kHz or less (1 edge count), 100 kHz or less (2 edge count), 50 kHz or less (4 edge count)
Match output (comparison)	When the present value and the comparison set value of the counter are equal, the comparison output is set (ON) within 30 ms and is cleared (OFF) within 100 ms by the reset command.
Output type	Open collector output 2 points 5 V to 24 V DC, 0.5 A
