| Common
Specifications |
|
| Input signal | Input 1: Non-voltage
contact or NPN open collector Input 2: Voltage pulse, “H”=4.5～30V “L”=0～2.0V Selectable Input 1 or 2 from the front key Note for wrong count by chattering when using relay contact. |
| Input frequency | Selectable from the front key, HF range (5Hz to 1kHz) or LF range (0.0166Hz to 100Hz) |
| Cut off | 0 to 10%: Programmable from the front key. |
| Latch / Pose input | Latch: hold display of
instantaneous and integrating flow rate,
and data output. Accumulated integrated
count and P.O. output will be insulated. Pose: hold display of instantaneous and integrating flow rate, and data output. Accumulated integrated count will be stopped. Integrating synchronizing pulse output (P.O.): Input and isolation output. Output signal is NPN open collector output. |
| Reset | reset totalized value and primary setting value |
| Blackout | All programmed settings are stored in EEPROM for a minimum of ten years if power is lost. It does not count when shutting or losing the power. |
| Noise rejection | 1000V against the power line noises |
| Withstanding Voltage | Input terminals - Case :
AC2100V each for 1 min. Power supply terminals - Case : AC1500V each for 1 min. Power supply terminals - Input and Output terminals : AC1500V each for 1min. Input terminals - Output terminals : AC500V each for 1 min. |
