INPUT SPECIFICATIONS

■ Totalized Counter Input (high speed): Dry contact, 4

points

Commons: All negatives

Max. input frequency: 10 kHz

Minimum pulse width: 50 μsec.

Max. counter value: 999 999 999 (reset to zero at overflow)

Sensing: Approx. 5 V DC (pull-up resistance 22 kΩ); ≤ 0.8 V

at Lo; ≥ 4 V at Hi

Caution: The totalized counter itself can accept frequencies

as high as 10 kHz. In order to eliminate unwanted input by

chattering, be careful to choose an input device to be free

of the problem (e.g. mercury relay).

■ Contact Input: Dry contact, 8 points

Commons: All negatives

Sensing: Approx. 5 V DC (pull-up resistance 22 kΩ); ≤ 0.8 V

at Lo; ≥ 4 V at Hi

Sampling rate: 50 msec.

Totalizing counter function

Number of input channels: 8

Max. input frequency: 100 Hz

Minimum pulse width: 5 msec.

Max. counter value: 999 999 999 (reset to zero at

overflow)

■ Counter Reset Input: Dry contact, 1 point

Commons: All negatives

Sensing: Approx. 5 V DC (pull-up resistance 22 kΩ); ≤ 0.8 V

at Lo; ≥ 4 V at Hi

Sampling rate: 50 msec.

Logic: Enable at pulse edge sinking
