Contact Inputs
For contact inputs, the contact must have a switching capacity of
2.5 mA min. at 12 V. If a 680-W resistor (1/2 W) is used for R4,
reliability will be improved.
Connections of Single Solid-state Inputs
The following illustrations show how to connect a single solid-state input to digital counters connected in parallel. The H7AN has an input resistance
of 4.7 kW. If the number of counters is N, the total input resistance will be 4.7/N kW. In this case, the high level input signal voltage can be calculated
as follows:
(4.7/N) x E/(4.7/N + R)
Determine the value of E (V) and R (kW) so that the high level input signal voltage will be 5 to 30 VDC.
Connections of Single Contact Inputs
The following illustrations show how to connect a single contact input to digital counters connected in parallel. If the number of digital counters is
N, the total contact input current will be 2.5 x N (mA) at 12 VDC.
Solid-state Contact Input Signal Levels
1. High level: 4.5 V min.
2. Low level: 2 V max.
4.7 kΩ × E/(4.7 kΩ + R1 or R2) must satisfy the above level.E: 30 VDC max.
(12 VDC if power is supplied from the external power supply.)
